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 product but has failed two out of three times
September 5, 2022
This is exactly what I want and need but I've had 2 out of the 3 I've ordered fail within a couple uses. BatteryJunction has taken care of me each time but I'm not sure if I've been very unlucky or if this thing has a problem with the USB wall charger I use.

With this third one I'm trying a new Anker charger instead of the old Samsung one.

Good Power Bank

Finally can use my extra rechargeable batteries to this Xtar Portable Charger and Powerbank.
Very useful because you can use it as a charger as well. And it is not bulky to carry.
I am very satisfied with the charger.

Great battery pack

This is a nice little battery pack. I like that I could use my own 18650s. It is small and compact. It also has a nice display giving lots of information. 5 stars

Great Power Solution

I really like the fact that this can be used to charge my batteries and and use as a power bank if needed. Nice to be able to pack a combo charger/power bank when going on a trip. Great product idea by Xtar.
