Many appreciate its multiple ports and consider it a good value for the price. However, some customers find the device to be bulky and heavy. A few users also noted that the power bank can get warm during use.

    When I opened the box, it was at 80% charged, so I plugged it in. I used the cord that came with it. It charged to 86% and stopped. The USB outlet was super hot, so I tried it in another outlet and same, then tried another cord and another outlet. All got super hot and it never charged over 87%. I had another powerbank charging which was 36,000mAh and it was fine. Went from 45%-90% in the time this one went from 80-86%.

    Only charges to 87% so it got 4 of 5 stars, seems a fair trade. Otherwise works well

    Energizer brand power pack. Using even a 6.2 V charger, it took almost 2 days to fully charge from new. Need better instructions.

    Because "I HAVE THA POWER!!!" Went on a weekend camping/ hiking trip out in the sticks which required a lot of Google maps and music. I was able to keep routing and rocking all weekend long thanks to this itty bitty box. Highly recommended!

    Does as its intended for and helps during trips so, I would have to say its pretty much all you need plus the charge with the C to C comes in handy with the newer gen phones.

    The battery doesn't come with a wall plug in, just the tiny usb cord that you would need to plug into a wall adaptor. More importantly, it takes a long time to fully charge. There was virtually no change for hours using the usb wire it came with. I ended up using a usb wire from an old laptop. That got the charge percentage to start to increase, but even then it was slow.
