Charge a jackery 500 with a gas generator and show us how much they can charge a jackery with 1 gallon
You know what you're talking about. I figured my 36 volt charger needs a 200 watt supply. Can I afford the losses? The easiest & safest way is to use the charger it came with. A 42 volt 2 amp charger. Most of my riding is done with a peddle assist at 60 to 150 Watts or so. My 350 Watt motor is set for a 7 amp limit on a 15 amp controller. I'm good with the speed I get with a 30T chainring. When you say a 30 percent increase in range, that is pretty darn good.
Thanks for the guide & introducing the Jackery.
How many watts of solar panels do I need to charge a e-bike that's 500w and the battery is 48v and the other e-bike is 1,000w and the battery is 48v.What will be the fastest way to charge e-bikes using solar panels ?
Hey Hobo, please do a video charging your bike with a solar panel and charge controller only.
Never knew i could charge my 48v 15ah E bike with my Jackery 300 😁 Thanks HoboTech!
thinking about buying a jackery 300 to charge my 48 volt 20 amp ebike hope it works 🤷
I have been charging my ebike with only solar power for over 2 years. A bit more then 10,000 miles….
The power comes from my bike trailer that has two 100watt flex solar cells with a battery box that inputs up to 130 watts from solar , holds 400wh and outputs up to 300watts 110v AC….
It will propel me up to 50 miles a day from the sun carting over 150lbs of camping stuff….
It’s all extremely reliable…
I needed this video a year ago! Glad I found it. THANK YOU!
I charge my Sur Ron in the desert using a Montek 1000 and a Bluetti PV200. No I'm not trying to carry this stuff on my bike. I simply plug it in when I return to my campsite. Since the Montek has pass through charging it works well. And I bought both thanks to you Tom. Early adopter for the Montek and I also bought the solar ACOPower fridge/freezer due to you. So I run out of water or food while camping, but not power. Thank you.
Totally educated and amused now on charging the ebikes. Thanks.
Excellent Class ! Thanks Professor.
massive help thanks for the info
Thanks for the great advice!
Thank you for the video.
Great Job professor -you are still taking me to school. Perhaps you should have a chart for the newbies on watts amps and volts and hang it in the background....
Thanks Iasked a question on another video yesterday. This video answers it... Thanks
I splurged for the 1000 with two 100 watt panels. Been wanting to get Jackery system for some time. The discount and your great as usual video forced me over the edge. I did avoid the Yacht Fund. Some folks just have way too much money compared to their value.
"On the cheap." My favorite words. I'm looking for a sub-thousand dollar e-bike as strong as possible and a solar + wind generator that will run a couple of fridges and a freezer as cheaply as possible.
Nice video, thank you😊
I bought one of the 1500's and the 4 solar pannels. It may not be enough for what I need but I can feel comfortable enough to have ice in my Rum and diet for the next few years when the power goes down.
thx, really helps
very cool vid i might have to try this out
Having a solar system to charge a battery, which is then later used to run a 120V inverter to power a charger for your e-bike battery will lose some efficiency in the extra conversions-- but it is a practical solution, since your solar system can harvest energy all day and you can charge the bike battery whenever convenient. Buying a special charger that takes direct solar panel or battery voltages (say 12 or 24V) then converts it to the voltage to charge the bike would be more efficient, but most bikes already come with a 120V charger that you'll want to have to charge from grid power anyways. plus you'd probably want an extra bike battery to leave on the charger while you're out riding during the sunny parts of the day.
yes its the charging during the day whilst on the move aspect that is inconvenient. I think it would work better to fast charge top up while getting a meal at some stop than rely on the sun, the angle of the panels etc.
While camping I was hoping to get a small wind turbine to run overnight and charge, but they are a bit heavy, although pack down small. 400w
Great value, and comfortable to ride
My e-mtb E-CELLS brand bike has TWO batteries but the bike designer, here in Pahrump, Nevada, made patented frame plug for charging BOTH 52 V batteries simultaneously, greatly simplifying charging.
I've been charging my e-bike battery (along with my other power tool batteries) with my sogens since I got the bike 1.5 years ago. The price of a kW on our grid is $.05 winter and $.08 summer. So it costs me $.03 - $.05 to charge the larger 556Wh battery. The ROI of purchasing an expensive sogen to only charge your batteries is...forever However, if you already had the sogens, why not take advantage of them. What really would be great is if the bike batteries had pass through charging, i.e., you can use the bike while the sogen on the bike rack is also charging the battery. Could almost double my riding distance on a looong ride.
grid power is so cheap, it's really hard to compete with unless you are talking about a remote cabin that would cost millions to connect. but when the grid goes toes up they are sweeeeet. (Texas this winter, cough cough 🥶) I like the fact I can run my ebike as much as I want with no energy bill. I'm sure I'll spend more in tubes, tires, and chains over the long haul than energy though.
Incorrect, once the kw come to your home it all depends on how many ohms your homes grid has, over time it increases, after that it depends how efficient is the inverter and or chager you are using, furthermore heat disipation is a real thing. Energy is lost after your meter.
In conclusion, you may pay for 1kw but your ebike battery will never be able to obtain that amount.
Just checked out your online store, very cool.
Here I am in the middle of the night laughing my ass off!!!👍👍🇺🇸👍👍❤️❤️🇺🇸❤️❤️👏👏🇺🇸👏👏!
Hey Hobotech. Great video! Around the 5:30 mark you were talking about the advanced charger and were saying the adjustability is in the amps (how fast you charge the battery) and the percentage of charge. As far as the physical output of the charger what is the adjustability that does that % of charge function? Is it the voltage output? If so, what voltage would you charge you battery at to get it to just 80 or 90% ?
Thank you.
@HOBOTECH Thanks for all of your very helpful vids! Do you have any experience with using, or seeing someone use, the “tarp-like” Solar Panels? Such as those offered by P3 Solar, PowerFilm, or the Off Grid Trek Solar Blanket?? Yep, I know, they are VERY expensive, relatively speaking. But on the plus side, they do offer light weight and a small size footprint when folded/stored, which is beneficial to backpackers or HAM radio operators in the field.
Any suggestions on high wattage AC charging of portable power stations? For nomads it would be great to charge with free AC during a library visit. And if remote decreasing generator run time when the skies are cloudy could save a lot of gas.
Thanks
Genasun makes high quality boost MPPT solar charge controller.
They are used in solar bike competition and in professional sailboat competition, so they are high quality. But with quality comes price.
The controllers are not configurable, so you order the one that fits you battery.
On bikes they are normally used with PVs mounted on the bike on on a trailer.
For a $200 Genasun just buy a Jackery and have it for many other uses ... including charging different bikes.
@@HOBOTECH yes, as I wrote, they are expensive, but a "solar generator" is larger and is not waterproof.
But for stationary system, a solar generator is probably a better option, while a boost MPPT is better for bringing solar on a long multi day bike trip.
Thanks for the info. i have an E-CELLS 2 motor, 2 battery dual suspension mountain bike for hunting in Nevada and for general recreation. MY OFF GRID CHARGING SYSTEM: 1.)Off Grid TREK 220 watt solar blanket charging a 2.) BLUETTI AC200 MAX battery. My factory AC charger plugs into the AC outlet on the BLUETTI and VOILE'! my batteries get charged thru a single port on the frame
For security and his wind tie-down I cable lock the solar blanket to my MAZDA CX-5 roof racks and connect it to the BLUETTI.
You learn me today!
Newb question, could you connect the eBike battery directly to a Solar Generator that supports various DC outputs? You do lose some efficiency when converting DC to AC then back again to DC.
Pick up an MPT-7210A, make a cable, and charge directly with a panel. Much less loss with just the one DC-DC boost converter.
Exactly, and I have 30+ years of small solar experience, before I got into ebikes. This is a bogus "solution".
Thanks I've been looking for a straight answer like this.
Thanks I bought my jackery 240 with your advice and I’m happy with the results but wondering if a 10 amp solar controller works with my 100 watt panel with the jackery or should I change anything
Did you find out if that works? I am looking at our first one, and thinking of a 240.
Think i can trust the BMS on ebike 48v batteries? Okay to charge at 60v5amp using solar directly? Also wonder how cool it would be to power the bike directly from a solar generator, some have a good space for it. I find it a lost opportunity that these bikes don't come with solar in, USB and low watt 110 inverter out.
I don't use a silly jackery to charge my ebike
All I have on my camping trips to charge ebike is 2 solar blankets 200w and a 80w, a ctkev300 mppt solar charge controller cheap from aliexpress and connections I made to connect battery and solar blankets to charger.
Takes around 4 1/2hrs to charge my 52v 20ah battery from 43v to 58v .
I have a Rad Power bike. Can I charge my battery AND ride it at the same time. Or must the Rad battery be switched off to charge?
Thanks for this vid! Now can you charge a PHEV like a Toyota RAV4 prime with a solar generator and which one? Might be a good future video! Thx
If my bike battery has to be switched on to charge, can I charge it while I use it, with solar, or some spare batteries I have fixed to the pannier?
Goodmorning Professor Hobo
Thank you! And very funny. I enjoyed your jokes immensely.
Thanks for your great info, I would like to get that blue adjustable battery charge , could please tell me where to get it and the model number,I have a 48volt battery on my ebike as well. Thanks again.
So for jackery 500 too charge 48v 5a do I need 600w panels.What panels are best for jackery
I have the Aventon Level e-bike, I just got the Jackery 300 (solar panel on the way) from what I understand here I should be able to charge or at least replenish my E-Bike battery. Just wondering if it's safe or if anyone else has tried this combo?
Thanks for the overview. They say use the charger for the specific battery
Thank you for doing this video I learn something. Also went back to check out how you built your e-bike I didn’t know you did that I would have learn a lot before purchasing my firs ebike. May be you can start getting sponsored by this many electric bikes and review them 😃
I've had about a dozen brands offer to review their bikes. All fell through either because they didn't follow up or they wanted me to review trash. I finally did get one to commit but they screwed me over in the end. I basically gave up on bike reviews.
I goto Bolton ebikes on utube. He's out of Grass Valley Ca, but his ebike reviews are candid, also tips and products. Hohotech is the best for solar all round ideas, tests and reviews plus he's a wit.(funny with dry sense of humour)
Love his sense of humor 🤣 exactly what I’m thinking he says it next lol.
Best guy for solar for sure you help me pick my first Jackery. I recommend your videos to anyone trying to learn about this subject. Thank you
I was searching for the adjustable 1-5 amp charger for my EBike on your website. I could not find it. Have the link for it? I found a domestic supplier that was out of stock and Alibaba also lists the item from China.
@4:17 so can you charge the bike battery while riding and bike is powered on?
I use my diy solar power station to power my 60 volt scooter with 2100 watt hour battery. Takes 2 or 3 days to make enough energy to fully charge the scooter, but I don't ride the scooter every day anyway. I ride the kaabo wolf warrior electric scooter.
Should you drop ankor and charge your lithium batteries or get solar sails
My brother… the inverter is not the energy waster.. it’s the rectifier taking it to DC power. Touch the power brick you can feel it HOT my man. Great video.
So the sinch? Adventon will it charge a well sinch is 750 but it's lime that model 750w 48v 12.8 a it will harge that?
I had to look up what a ‘instant pot’ is.
Never heard of them.
I like food more than bikes.
@The Tired Horizon I love my Insta pot too. Cooks meat stews, dried beans, lentils etc. super fast and delicious. It doesn't do good however with starchy potatoes or pasta as it creates a steamy bubbly mess. Any tips?
instant pots are neat. they do however have a large peak power, so you'll need a pretty big inverter/battery combo to run them. crock pots have a really low & constant power (75w low, 150w high is typical). they can be run from a very modest inverter. Once the instant pot heats up the duty cycle is low. Their total power consumption can actually be less than the crock pot, since the instant pot will cook in 30 minutes what takes the crock pot 6 hours.
@@cavemancamping Thank you. I'll try that.
I was looking to buy a boost charger to charge my ebike battery from solar directly. After seeing your video and the risks with that I will just use one of the portable power stations I have and use the charger that came with the bike to be safe. Thanks for another informative video.
I've been using a mppt boost controller and solar for years and you don't have all the weight.
I use a cargo cart instead of a rack, love the idea of getting across a state on solar and use of an ebike.
Hello, Thanks for the video.
Do you know if it's possible to charge a recent bosch battery charger (4A) with the 240w jackery ?
It would be pushing it to the max as shown in the video.
I have a bosch battery and charger 36V x 4A + 15% loss = 166W
Safer to go for the Jackery 500. You would get approximately 2.5 charges from the 500 if my math is correct 🙃
Would you be able to charge two Jackerys at the same time off the same solar array? And if you could, would it be possible to add more panels (due to non-sunny days) than the recommended wattage and it not damage the jackerys? Ex: I have 2-100w renogy solar panels on my van roof- winter days I only get about 35-70watts. Could I add a third panel to boost the watts. If this is all possible I would totally just buy another Jackery and kind of hook the systems together.
You can't share a solar array. You need separate panels. You can over panel but you can't over volt. Stay within the Jackery voltage limit you can use as many panels as you want.
Question - I know enough about electricity to be dangerous, so:
If my bike charger has a 42Vdc ---4A output that should mean ~168W draw from the Jackery/ other power station?
The motor is a Shimano so 36V which is why I guess it can have a higher amperage with the 42Vdc draw?
I have a Jackery 1000 and recently while using it when it hit 20% it started rapidly going down to zero like 1% per second before it hit zero and shut off. Any ideas what might be going on? The drain k was using was about 200 watts.
You need to reset it. Charge it fully then hold the display button until the screen flashes. Now it should be calibrated.
@@HOBOTECH Thanks. I'll give that a shot.
Mr. Hobo, do you think I could use something like this to charge the SLA battery on my Ezip TrailZ to extend its range too? Or would any battery backup at all do that? I haven't bought a battery yet but was thinking of getting something more like a 500w battery. So hopefully a little better than the Jackery you're showing here but that's about the best I could do, I'm poor if my E-Zip bike didn't give that away lol
If your SLA battery has a charger, yes.
@@HOBOTECH It has the included charger, would you think that could be charged while the bike is operating or would extended range mean that I'd need to stop and let the battery backup charge the bike batter while it's idol? I can tell you that the charge port on the battery for this model is different than the port that outputs power to the bike. That would seam like it would make it possible at least to have power coming in to the battery and out at the same time, but I'm not positive. Technology is great but can be frustrating!
Thanks Tom! I'm hoping for blue skies too!
Genasun Boost controllers. They offer various voltage and chemistry models, and have the highest efficiency, conformal coating, and successful applications from the Antarctic, marine, and mountains.
Good video except no love for the jackerys 300,that's cold man.
Also when I built my e-bike conversion I used 2 18volt power tool battery's to power and with how fat I'am I got 2 9.0amp batter's that take me anywhere but the makita quick charger is a bear running up my jackery up to 200 watts witch can only recharge one pack then pretty much dead jackery. Yet the theory is sound.
In your research what make smart charger did you choose ?
Could you possibly add in a smaller battery as a capacitor to even the charge to account for clouds.
My Himiway is 48v 17.5Ah. 2amp charger. Fat tire mountain bike 750w, 30+ miles, pretty happy with it. $1500 Thanks for the video, I've been trying to work out what I need, at minimum, to charge it from solar for emergency use. Looks like a little Jackery 240 will work, and the 500 would be better for frequent use. Thanks.
I don't need the information in this video. I just watched to support the channel. Thanks, Tom.
I might have considered this if I could get the jackery for $100, but spending $200 will buy a bunch of battery cycles plugged into my home outlets. Not to mention the time spent hooking it up, changing solar panel angles and everything. I am not sure I could ever recoup that $200 before the jackery and ebike battery run out of cycles.
thinking of buying a jackery 300 to charge my 48 volt 20 ah e-bike I hope it works 🤷 thank you
This is the video we needed! Do u think I could use a 4a ebike quick charger with the golabs 300w inverter
Probably.
Please do a review on the new generator WATTFUN 300. I hear they are giving the Jackery a run for its money!
Nice
This video is almost perfect for me, I have a problem I hope you can help:
I have a 48v 15A ebike battery with same as yours 54v 2A charger, I bought an Allpowers 300W Generator to top up battery while on long rides out camping thinking it would be fine. However it cuts off after a couple of seconds when trying to charge, no matter how charged my bike battery is.
the manufacturers help says it is drawing too much initial peak power (though the Allpowers unit claims to handle 500w peak)
The unit will power a 120w nut grinder on AC, so I don't know why it can't cope with the ebike chargers 108w ish.
Any advice would be appreciated before I try to get a refund. Shame because the unit charges my 18v Dewalt batteries fine. I am in the UK (240v AC) , though my bike charger is Chinese.
@@RealJohnnyDingo thanks for your input. I have just bought this Hobo a 'cup of coffee' so hopefully he will respond
Can I charge it while riding the bike?
Hey professor, a question off topic.
What is the best solar power station solar panel package for sale today. Best bang for the buck so to speak.. thank you
I get asked this dozens of times a day so I guess I need to make a video. The best one for sale is a tie between the Bluetti AC300 or the Ecoflow Delta Pro. See my reviews.
How about a cool efficient direct method. Charge two at once with a simple balancing resistor and an alternating tidal current from the smallest of solar panels?
What if you have a usb c pd port on you panel and on your battery pack. Is it any safer to charge directly from solar with that type of setup?🤷
PD can only do 20v and won't work for batteries.
@@HOBOTECH Ok, thanks!🙂
@@HOBOTECH I saw an ebike battery pack that had a solar charge controller built into the bms. Is that type of setup ready to take power directly from a solar panel. I don’t recall where I saw it otherwise I would look for myself. This was not using usb c BTW. Thanks. 🙂
Amazing concept. Can you do it on the motorcycle ?
I do this with my e board Lacroix ss 2582 wh 72v.....my euc 100.8v 3200 wh and my bike onyx rcr with custom battery 72v 54ah and i charge all off my eb500
They do make MPPT Boost charging units specifically for solar e-bike touring. Boosting the voltage is a much safer and more efficient way of charging.
The racers' annual Sun Trip from France to China use such units and using your wall charger disqualifies you from the race! There are some knockoffs
out there that work but are not trustworthy. You get what you pay for!
Yes 👍 ⚡🔋
Will you review the new EB120. Pleeeeease
I am new. To eBay king and have a lot to learn. I want to bite camp and maybe eventually do coast to coast on an ebay can it be done is it possible
I have a 240 to charge my ebike…the 240 fits in my pannier perfect…now all I need is a 65w solar panel that also fits in my pannier…better make it 100…I live in Canada
Jackery is da bomb!
Bluetti is the bomb.
Ecoflow is the best if you ask me. Can charge from 0% to 80% in an hour...or to 100% in an hour and a half.
I thought you said 50% off sale and almost had a heart attack that I missed it…LOL.
If electric bike batteries are generally standardized at specific voltages / amperages, why aren't there solar generators that specifically output charges that match those standards? It seems like a huge amount of energy is being wasted converting the DC output of the generator to AC so that chargers can immediately convert it back to DC. Personally, I think the solar generator industry needs to step up their game and build units with additional DC out options. This is one of the largest sources of energy inefficiency left. Anyone who's ever needed to charge their laptop from an external battery knows how silly this situation is.
I might be a little simple minded but when the title specifically says…how to charge an ebike with solar, that’s exactly what I expect to learn. I don’t need an entire dissertation on the sizes of generators. I need to know which specific size to use, which solar panels to use and best charging practices. How to plug everything together would be helpful too. It must be a guy thing.
with the price of gas, I might need to get an ebike one of these days. I have a friend that rides an ebike 9 miles each way to work. He says he can ride up to 20 miles an hour. I just don't know about when it snows or rains.
I do this myself. My tip would be invest in good rain gear. A good gortex type outer shell to keep you dry that is big enough to layer warm clothes under it. Also some sort of shoe covers to keep water off them and your socks. That gap between the cuffs of the rain pants and the top of your shoe is right in the splash zone of your wheels.
You can get a cheep jacket and pants off Amazon for 50 bucks or so but they don't breath well. Good stuff is going to run a couple hundred for the set. I started cheep then upgraded. Now the cheep set is stored at work as an emergency backup should the weather turn unexpectedly mid day.
Invest in fenders too to keep the mud and water splatter off of your backside.
I can use an ebike almost every day. I'm not as hardcore as I used to be so I drive on wet or icy days. i coast and let the bike do the work when I don't want to get sweaty. I pedal in cold weather to stay warm! on the way home I let it rip and get some exercise. the bike was $999 so even at $3/gal gas it will take a while to break even, but I'm having a good time which counts for something 😁
@@RealJohnnyDingo I definitely don't use my bike as my main transportation as I love my Kia Optima hybrid car. But I do have a Diamondback Lux women's mountain bike that my husband installed a 750 Watt Bafang mid-drive cycle kit from Luna cycle. I've had it for 4 years and I have over 1,200 miles on it so far. I love my ebike. It only cost us $1,350 total because I got my bike brand new at 50% off.
@The Tired Horizon Yes and I've had my electric bike for four years now and still haven't gotten any :(
I was hoping to see you charge with PowerBens. ;-)
