Xtar PB2S

Portable Li-ion Charger and Powerbank

The Xtar PB2S will quickly become your favorite dual-channel charger for lithium-ion batteries. Complete with a powerbank function, this charger not only keeps your batteries in proper working condition but your favorite USB electronics too. The PB2S supports both QC3.0 and PD3.0 fast charging methods for the quick revitalization of batteries, smartphones, tablets, and more. Additionally, the USB-C and USB-A ports work in conjunction with one another to charge two external devices at the same time. The Xtar PB2S has an easy-to-read screen that provides real-time information such as charging/discharging current, voltage, battery capacity percentage, and this information toggles between the two batteries by single-handedly pressing a button on the side. Another perk to the PB2S is patented Xtar features: 0V Activation Function which instantly revives over-discharged batteries and returns them to their original functioning state, and their three-stage charging system which starts with a trickle current, bumps up to a constant current and then moves to constant voltage once the battery is fully charged.

XTAR Hits One Out Of The Park
July 28, 2020
Ok. So I have this primal urge to have power, lots and lots of power. And when the local grid goes down here in south Florida I want to still power and charge all my "stuff". I have more powerbanks than you could imagine. Even bought the kits from overseas to build some 8 cell 18650 models. That being said, this little gem is my favorite of all. Top notch. Just the feel of this in your hand shows the quality in the design. Ergonomic, with that rubberized casing makes it a joy to hold. Power? It can take the big boys no problem.How 'bout them 21700's? 5000mAh each! (not included) USB C in and out with a clear and easy to understand display. Also supports QC & PD 3.0 in/out. Just a really refined work of art. Buy at least two, maybe a red and a blue, otherwise you'll find yourself placing a second order. Enjoy!

Nice and useful

I like this a lot, It recharges My battery and once it's charged I can use it to charge something else like a phone or other USB stuff. Cool right. Battery Junction only charges like 20 bucks for it and that's not bad.

Great power bank as well as 18650 charger at home or on the go.

Xtar PB2S is a perfect mobile power solution!
November 29, 2020
When I'm out for long periods of time, I have a few things that I need to charge. My cell phone is obvious, but I also have a flashlight powered by 18650 batteries. For powering my phone on the go charging my flashlight's batteries, this Xtar charger is a beauty. The display is easy to read and intuitive, the PD power output really helps get my phone fully charged quick, and it stays as compact as you can reasonably expect while powering two 18650 batteries. Truly a great and affordable choice for mobile power.

Top Tier Power Bank !!
December 25, 2019
This is a high quality power bank when used with either Samsung 50E Li-Ion cells or LG M50 cells. The addition of both PD and QC 3.0 make this Power Bank and PD an immediate hit. Very versatile I must also add to mention. Xtar has hit another homerun with this product. I highly recommend it.
