Review: Absolutely genius, A very useful and impressive device! - I ran into this XTAR one day looking for something completely unrelated. Decided to give it a shot, and fell in love immediately. For a few reasons, but mostly because after using it just for a day or two, it was obvious that the designers of this, took a lot of care, and did the research in order to make it remarkable, and it really is. So, full disclosure, I am a vaper. My daily device does use replaceable 18650 Lithium batteries. It can be annoying to try to make sure you have a fully charged one before I set off for the day in the morning. Hence why I had been looking for a device to solve that for me. This is fantastic battery charger, and if you use it just as that, you will be satisfied, it does everything that a standard charger will do. with all the latest safety features so it knocks the battery charger side of things out of the park in my opinion. When it is charging batteries, the info display stays on, not for 30 seconds, or 60, but until its unplugged. It supports fast charging (9v &12v QC) and lets you know when that fast charging is active with the voltage read out. It supports pretty much all sizes of lithium cells I know of other than maybe the extremely short side of the spectrum. It even protects the circuitry from reverse polarity. If you are like me and have the need to charge all kinds of stuff on the go, this is highly recommended.
Review: Flexibilty - I really like this battery bank. I like that the batteries are removable / replaceable with the standard 18650 batteries that fit in other items I have like flashlights. I can carry more capacity by just having more batteries to insert. I can use this to charge an 18650 for the flashlight by swapping them around. I can charge this with a portable USB-C solar panel, or in the car or an AC cube. What I wish they would improve is the durability, especially the lid. I drop it and the magnet attached battery compartment lid pops off. I like the magnet. Its slick and simple, but this is something I carry in a pack or pocket and I just drop it once in a while. The magnet ALSO pops out and I have glued it back in several times with epoxy or cyanoacrylate, and it just doesn't stay. A hit still pops the lid and the magnet goes too. Thankfully I haven't lost that tiny magnet yet. I don't hate it, but hopping they read this and maybe make a slightly better lid or a whole new rugged tested version. I think they could make something like this that uses their XTAR Lithium AA/ AAA 1.5 batteries, as a charger AND as a portable bank for charging other electronics. I would sure buy one. I think this an unknown gem for people who like to be prepared.

## Questions & Answers

**Q: Can i "fast charge" my phone with this using it with 18650 (5000mah) batteries?**
A: To get "10,000mAh" (1S2P, 2x5,000mAh type 21700 cells) you can also use:
SAMSUNG 50E 21700 5000MAH 9.8A BATTERY
I've seen these offered varying from about US$8 - $12 per cell.
9.8A continuous amps at BATTERY internal temp of 25C
Each cell is rated at 5000mAh, but the spec says the GUARANTEED minimum capacity is 4900mAh...which is pretty much normal for Li-Ion cells when capacities reach maximum levels possible with the technology. At a 1A current drain, the Samsung 21700 50E cells I've tested reliably provided individually about 4600-4700mAh to Vt=3.0V. 
(note: the Ah capacity of a battery or cell generally and normally decreases with increasing current drain. Example; a cell that tests to 4900mAh at I=100mA may test to 4600mAh at 1000mA current drain)
Warning: counterfeit batteries and cells are a problem in online commerce. Find trusted sellers that stand behind their sales and merchandise.

**Q: Can you recommend the type of battery to buy for this please?**
A: The higher the milliampere rating is, the longer it will last. Get a battery that is above 2500mHA

**Q: Does it have pass through charging?**
A: When I plug in the charger to a phone to charge the phone, or when I plug it into a power supply to charge the batteries inside the device the display lights up. When I plug in both USB cables at the same time, the display turns off, but the phone still shows that it is charging. That implies the device just passes through the power when both cables are plugged int.

**Q: Does it come with USB transformer?**
A: No transformer. Just the charger and a pretty decent USB C cable. Works great us it to charge my flashlight and ecig batteries when I am camping with a small solar panel. Well worth the loot.

### ⭐⭐⭐⭐ Love the idea, but the voltage measurement is wrongi
*by J***S on August 11, 2022*

I've got a bunch of 18650 batteries now that I've learned how to safely tear them out of various devices (ie., a laptop that doesn't work anymore with a removable battery? Free batteries!!). This makes this device perfect for utilizing those batteries! Now, my gripes: I have a Zanflare charger that gives me the right voltages of the batteries, and this charger will not show the correct voltage of the battery. It does seem to measure it correctly because it does display the correct %. For example, plugging this cell into my Zanflare tells me that the voltage is 3.82v. My understanding is that many lithium ion batteries are fully charged at 4.2v, and the XTAR does tell me that the battery is at 61%. It does seem to measure the correct amperage when charging the battery via USB-C. My second gripe is I wish the cover's magnets were stronger. The magnet feature is a super nice touch and I really like it, but for example if I allow my kids to use the battery pack, those batteries will be lost. I'd have to tape it shut but then I have tape all over my nice battery charger. I also wish I could give this a 3.5 rating. I'm not happy enough with it to give it 4 stars, but not unhappy enough to give a 3. I guess I'll leave it at a 4 since many vendors do work hard for ratings since inaccurate bad ratings can kill a business, but hopefully this review will help some potential buyers make an informed decision.
