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.

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.

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

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.

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.

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.

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!

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.
