Yes.

No. It is waterproof 50 meters depth.

@@ShenzhenXTAR water can go inside to the battery if you don't pay attention

Their switches are different.

Sorry, the T1 is not waterproof.

Sorry, we have no power strip converter. Maybe you can search it on Amazon.

Sorry for the inconvenience. The usb output of vp4 plus supports max 5v 2.4A. What power does your cell phone require? Please contact us by email (info@xtar.cc) to have more details.

No, the AA and AAA lithium batteries can not be charged by regular chargers. We recommend you use our new all-in-one charger MX4. www.xtar.cc/product/xtar-minimixer-mx4-charger.html

Sorry, we only made Enlish version.

无法充电可能跟很多因素有关，建议联系官方客服处理。

Yes. Most of the XTAR chargers have this function.

They can be compatibe with new BC4 charger.

@@ShenzhenXTAR I bought a BC4 a year ago. Is it still the NEW one? or Do you have a different model number?

You mean turn off the USB-mode?

It is coming now.

We appreciate your support for XTAR. Hope we can talk more about night diving and spearfishing.

The grading mode is to test the battery actual capacity via charging-discharging process.

We recommend the adapter with power >36W. XTAR has PD45W adapter. www.xtar.cc/product/45W-USB-C-Wall-Adapter-191.html

We have a new charger - MX4. It can charge 4 types of batteries: 3.6/3.7V Li-ion, 1.5V Li-ion, 1.2V Ni-MH, LifePO4. www.xtar.cc/product/XTAR-MX4-Charger-216.html

Use a plastic piece to block it so that the switch cannot be pushed forward.

Some seriously over-discharged batteries can not be revived successfully.

The PB2SL can charge your 18650 and 21700 batteries, no matter it has protection or not.

Thank you for your advice. We will update the video later.

It’s mwh, equal to around 2600mah.

Yeah, they were doing the clickbait thing.

The capacity is 2500mAh, energy is 4150mWh. We have more details on our official website: www.xtar.cc/product/XTAR-1.5V-AA-4150mWh-Battery-210.html

4150 is mwh (working hour), equal to around 2500mah.

In the field of rechargeable 1.5V lithium ion batteries, almost all brands rate the capacity with mWh, so we followed this way. But in order to explain clearly, we added on our official website page with "capacity 2500mAh, energy 4150mWh". Also, we wrote a blog post to explain the difference of mAh and mWh. Here is the link: www.xtar.cc/news/Demystifying-Battery-Ratings%3A-mAh-vs.-mWh-252.html

@@ShenzhenXTAR Again, weasel words and excuses. Litium ion rechargeable batteries in this size are a minuscule part of the market. The rest of the market uses mAh. It is CLEARLY designed to be deceptive. It is CLEARLY a marketing strategy that NO-ONE else in the industry uses. Just admit you are trying to scam people and move on. Your excuses are making it more and more obvious this is your goal. All those 18650 batteries are in mAh. Sure they are not 1.5v, but the point stands that it is only this tiny, scammy, segment that doesn't.

@@GTrainRx7 actually, I wish that everybody would use WH instead of AH because AH says nothing about the energy stored in a battery. AH is the unit used to fake, WH is the true energy capacity.

@@GTrainRx7mWh is the much more better unit to have a comparable capacity for this kind of batterys. The reason is simple: for compare batterys with mAh unit you allways need to compare the voltages curves. The output is not 1,5 volt for the hole discharge, it drops to 1,1 volt for the last 20 % of its capacity, normal 18650 batteries have a voltage curve and not a stable voltages. mWh includes the voltage so it is the overall energy stored in the battery. BUT XTAR use the capacity of the internal battery for the "4150mWh" value. The mAh rating is for the energy available after the voltage drop from internal 3,6 volt to 1,5 volt (or 1,1 Volt). This is in case confusing and some kind of marketing. But for example allmost all powerbank manufacturer do the same and put the capacity of the internal batterys to there specs. We have tested the batterys and you can find real testing results on our website: www.akkuvergleichstest.de/ at the moment the XTAR 4150mWh batterys is the battery with the highest capacity. Yes it is maketing but the capacity is really good. It would be the best for this kind of batterys if the manufacturer would label the batterys with the capacity in mWh that are available at the outputs.

We have AAA li-ion batteries, here is the link: www.xtar.cc/product/XTAR-1.5V-AAA-Battery-With-Indicator-200.html www.xtar.cc/product/XTAR-1.5V-AAA-1200mWh-Battery-173.html

Sorry for the bad experience. Please contact us via email info@xtar.cc for the after-sale service.

Thank you for your advice. Then the charger needs to be programmable in voltage. This could potentially be added to our next flagship charger.

Thank you for your advice. We have always put charging safety in the first place, and achieve efficient charging on the basis of maximizing battery life. Also, we will forward your needs to our engineering team.

the L supports larger batteries like 21700 cells with the cover on. the normal PB2S also supports 21700 cells but with the cover off.

@@terminator8220 not true I have the pb2s and it supports 21700 with the cover on

Sorry the VC4L can't charge the new 4150mWh AA battery.

Yes, it is not waterproof.

If you need aftersale service, please don't hesitate to contact info@xtar.cc to provide more details.

Our VC2SL, the 2-slot charger also has the power bank function, and this charger supports small batteries like 14500. www.xtar.cc/product/XTAR-VC2SL-Charger-189.html

The runtime of D26 1600S is 2 hours, with turbo mode.

Thank you for your feedback. Our engineering team will consider the possibility of a new charger.
