I like how you can adjust the voltage for what item you are powering. It was a good price for the item and arrived fairly quickly. I really like this power bank!

Used the bank for 30 - 40 times and noticed the battery started losing capacity after 5 or 6 charges.. I suspect they manufacture put inside the worst quality battery .

Deceptive description. Clearly states that there’s no auto shutoff yet the USB shut off. Can’t power my camera with a dummy battery which is the only reason I bought this. Maybe the barrel out doesn’t shut off ever but the text makes it sound like you can use the USB with no auto off. Feels like a solid product though.

Warning. The seller of this item does communicate and seems pleasant enough but has trouble resolving issues!!! Be careful. You could end u with a stack of expensive dead junk. The ability to vary the voltage all the way to 24 volts is great. That being said, the previous generation would short out after just a few cycles. Smelled like burnt electronics and was dead. I liked them so much, I bought replacements, thinking that maybe I just had bad luck. Nope!!! Contacted the seller. He needed date codes. I provided them for two of the batteries immediately and took a bit finding the third. Sent pictures and irder confirmations and all I got was an "i'll get back to you with a solution ASAP" a month ago, then nothing. Clearly there is a new model (this product), and my dead ones should be replaced. All date codes were the same and I ordered the last set in March and contacted the seller within a few months.
