    Portable Power Bank Review

    Charging this power bank from a computer via USB can be slow, even when done overnight. Also, it is heavy so carry in an suitable backback or bag. Fortunately, it maintains the charge well and offers 3 output ports: 2 USB-C and 1 USB-A.

    Consider weight vs storage size

    Works well and it’s great that it has extra ports for different wires. It’s noticeably heavy when kept in a small handbag or purse but given the sheer amount of power it stores it makes sense, so that’s kind of the price you pay for extra charging. Consider physical weight vs storage size as the deciding factor when you purchase a portable charger. If weight is more important don’t go for this one. If you don’t mind weight and just want a lot of storage go for it.

    Great little battery pack. Perfect for being out for the day and having no way to charge your phone so it's not only convenient but makes me not worry about being out all day without a working phone

    Workhorse of a charger

    I bought a couple of these for a family trip, and they are workhorses that did what they were supposed to do. This battery has hours of capacity and is very reasonably priced. I purchased it for the value and was not disappointed. Be aware that these are bulky and kinda heavy, but you can charge a phone several times (3 or 4?) if this thing is fully charged. I think it's good.

    Great power bank and not really expensive!! Charged my phone and my wife's phone while we watched movies on our NY trip for New years eve. Fast charge even when in use. Only con I noticed was you have to use the proper block and get a fast charging block (25 watts or better) to achieve fast charge of battery bank.

    I traveled to Japan recently and this battery was a godsend. I saved my phone from dying while I was out taking videos and pictures if you’re traveling anywhere and know you’re going to be using your cell phone all day this battery is a must.

    This is a substantial battery backup at an attractive price. I also like that even though it is an imported product, it is a familiar brand that has always been reliable.
