Review: Great converter/battery box - I grabbed this and a generic laptop battery for an asus laptop (just because all 8 cells were in a straight line which makes it easier to rip apart for the cells.) And I stuffed them in this SLIM box, probably 2-4 mm thinner than my old 8*18650 box, whose ports are wearing out now after 5 years of reliable work! So i saw this looked as if it was from a similar company. Rolled the dice and it works great. The usb C is an input only but works well with 5v 2A cell phone chargers, just watch out it isn't Qc or QI so no quick charging it or you will zap it with 12v which is bad lol... anyway good solid micro usb which i thought would be handy i haven't tried the lightening input yet but if its like the other 2 its good to go. I did a test with two 5v testers and i got 4.3 amps out of the two outputs and it did warm up but it didn't over heat or drain faster than expected. So it maintains a good conversion even while running two 2amp outputs. while my old one only did 3 amps and would overheat after about 20 mins, so i rarely ran it over 2 amps so this is a massive upgrade for me. Id say the biggest downside is it doesn't reopen without a lot of shims and time. It has small D shaped clips that are about ever 2 cm's down the seem. So yeah, pick a new battery and don't expect to trouble shoot it after its together, but the descript explained that. TLDR: Great, works at 4 amps consistently. Can charge two newer phones but not Qc or QI not even to charge it. But It does a great job and will probably be a life saver in air ports post pandemic!
Review: It is screwed together so can change batteries when they fail - Works good, great to repurpose old lap top batteries

## Questions & Answers

**Q: Does this support pass through charging?**
A: yes

**Q: Do you have to fill all eight slots with batteries?  Or can you use 2 or 3?**
A: You must use at least one battery, but each of them will add more capacity to your bank. If you use 2000 mAh capacity batteries, 8 batteries = 16000 mAh.

**Q: What does it mean when the "IN" light flashes on the display while charging?  Showing 0% charged.**
A: ...yeah, i haven't bought these yet but i have one i bought already put together and that one flashs 'in' while it's charging and 'out' when it is discharging along with a number displaying the percentage of charge.

**Q: Bought this two days ago. Is it supposed to be slow to charge? 17 hrs to go from 48% to 86%... That's more than a 24 hr charge rate. Really?**
A: It depends on the current your power source supplies. A typical USB power supply charges at 1 to 2 amps. So...Yes. It will charge at a rate of 1 to 2 hours for each battery in the pack. If you have 8, 2 amp hour capacity batteries in the pack, it will most likely take roughly 8 to 16 hours to charge a depleted pack.
