    I love this charger. It is not lightweight if you are looking for something slim to put in a pocket or purse, etc. However, it does its job well (charging devices) and keeps a charge for a while. These are my favorite portable chargers. I use them for my phone mostly.

    I bought this after getting stuck at the airport for nine hours. My phone went dead, the place didn’t have enough outlets for all the people trying to charge... everything they had. Now I don’t have to fight for an outlet, this charger have loads of power for tablets and phones. Consider this if you travel with a family, not a bad alternative to having the kids devices die halfway to the destination.

    I bought this for my husband to take on his fishing trips. He loves it. He has even left it in the boat in a damp baggie and it still works fine.
