Does one really need to buy the NOCO Quick Charger, to fast charge a depleted pack? Answer: NO! Any USB C charger 65 watts or greater will do. Follow RollingTardis on Rumble rumble.com/user/RollingTardis - Jak na to + styl
Thanks again for all your assistance on my NOCO Boost X GBX45...
Happy to help!
Thanks for the video. I just ordered that same jump pack. I'm wondering if I should have got a better model.
Excellent video. Just purchased this unit and obviously didn't read the manual and would have tried to charge this with a 30 watt PD brick. Getting a 65 watt PD brick right now. Thanks. Keep up the good work, turtle and mock neck!
Thanks. You would be disappointed with a charger less than 65 watts.
Thank you
You revealed the truth and illuminated the way for travelers👌👍
Your Welcome!
Good video! Here are few things that I've learned from measuring dozens of booster packs. These may be useful to viewers about the discrepancy between advertised and measured capacity:
1) Watt-hours (Wh) is what matters. That's total energy. Amp-hours (Ah) depends on the battery voltage, so it doesn't tell the whole story. I'm glad this video included that information!
2) Advertised specs are for the battery cells themselves, without any circuitry. It's fine to measure the capacity via USB-C output, but keep in mind that's going through a buck/boost converter which consumes some energy.
3) Capacity depends on the discharge rate. Fast discharge (higher current) is less efficient, and will result in lower measured capacity. This is less of an issue with Lithium chemistries than Lead Acid, but still an important factor.
4) Many battery packs and power banks do not charge the battery up to maximum capacity, since that decreases their lifespan. I was just inside a Ryobi 40V pack, with 4.2V max cells, but the charger stops at 4.1V per cell. On the flip side, they will often cut off the discharge early for the same reason.
5) To truly measure capacity, like the manufactures do, you would need to manually charge each cell to full capacity, then immediately discharge directly from the battery at an extremely slow rate to avoid any heat losses, all the way down the maximum discharge voltage. Doing this repeatedly will limit cycles, but that's how you get the maximum capacity numbers they want to advertise!
So 23Wh measured via USB-C output at 1 amp for a 31Wh advertised pack is pretty reasonable.
I used to have a math formula to consider the loss of circuitry, lost it in the mess I have. I like to provide real consumer numbers, instead of drilling controlled lab numbers. Some viewers like it that way.
@@RollingTardis Oh I agree, the real world numbers are totally useful. I just thought some of your viewers might be interested to learn the details behind why advertised battery capacity doesn't match measured numbers 👍
@@colindgrant Always good to have the added info.
Great Video Thank You
You’re welcome
Thank you, I tried to charge the same NOCO GBX45 unit (new) with the ANKER Series 737 120W charger (new) but it didn’t fast charge the unit and the light didn’t glow… should the unit be fully dead before charging it!!
Should not matter on state of charge. Have you tried a different cable? I find that in certain cases, cables do matter. One time, I did notice if fiddling around too much, trying to get the light to glow, the fast charge would not work at all.
The charger I am using is the Anker Nano 2 45 W and it does indeed illuminate the fast charge light and the charging time was just over 1 hour.
My 65 watt charges in less than 25 minutes.
I just bought the GBX45 and I get the fast charge indicator using an Anker 45w charger and it is about an hour to charge.
It should not work with 45 watts. You may have gotten lucky. Interesting.
I agree but tried it with Anker Nano 2 45W and it lights up the fast charge icon. See if your boost pack does the same.
I do not have a 45 watt charger. It may be Noco changed the charge circuitry, to accept lower wattage chargers.
Is their an equivalent cigarette lighter that can charge this with PD in the car?
A simple search for PD Car Charger 65 watts, will result in many choices on Amazon, of course one can use eBay and Google Shopping.
All the power on the internet and ONLY on this video at 5:48 does anyone tell me how long the battery is supposed to last. THANK YOU!!!
Just noticed you turned it over... can't believe they put that information only on the product and in the tiniest sized font possible 🤦♂️😩
@@Samualninja I am one of the rare people, that is not trying to sell you a product. Because I used my own money. 99% of reviewers have their hands tied and can only tell the consumer, what a product has and what it should do. If they went outside of that boundary, they would not get reimbursed. 99% of reviewers get their product for free. I do not. So, I can give real facts to the best of my ability.
Where the heck did you get that shirt?
It is a Ragmans Pull Over Sweaters From AliExpress. Amazingly there will be a video on it, last week of September 2022 28th day.
Hi there , good video bro 😎, can U make another video using this GBX45 noco to see if u can really start a 6.5 gas liter engine or a 5.0 liter diesel truck, that would b a very interesting 🤨 video , if u can find a friend or family member that can help you to gather some cars 🚘 or trucks 🛻 to find out , just saying , keep up the good 👍 work
Got nothing on the platter of that type of tests.
@@RollingTardis
Oh me. Come on 😎 bro
I started 7 liter with this model...I'm talking dead as can be... I'm surprised it did. As these need at least 2-3 volts from the battery to work.
@@WizzRacing Excellent News on the performance.
There is testimony on Amazon of this unit starting a tractor trailer.
Just buy the Apple 70 watt Type C charger...Yeah it's $60.00 US but it does charge these super fast....
Why would I spend 60 bucks for Apple. When I spent 28.89 for the Anker. The difference of 5 watts means nothing to me.
@@RollingTardis I didn't buy mine. It come with my Apple Mac Book...Not to mention my PC has 90 Watt USB Type C ports...
But I don't trust cheap knock offs. I seen them toast devices that cost $$$ to replace. When they fail. Most of them are phones.
@@WizzRacing I trust Anker for Apple Charging. That tip come from Jessa Jones, who runs iPad Rehab. Fully aware of knockoff chargers.
Mine came without the bag
Monday or Friday, Packaged at the Factory.
@@RollingTardis sorry what does it mean?
Monday, is workers hung over from drinking all weekend. Friday, is F. it, can't wait to go home and get drunk.
@@RollingTardis jaja 😅
