    Worked well and charges rather quickly. Doesn't get too hot. The downside is you have to carry your cables everywhere with you so unless your camping in the woods, you could just plug it in?

    This battery bank is amazing! We took it to Nepal on a three week backpacking trip and it kept our phones and watches charged the whole time. We only needed to charge the bank once during our trek. Now that we are back home it doesn’t get used as much but when we need it the charge is still there even after not charging it for weeks.
