    This is a heavy duty battery meant for emergencies and not to carry around with you, although you probanly could take out a mugger with it. It does take a while to charge, but for obvious reasons. It’s perfect for what i needed it for, but just be aware of the dimensions when you’re deciding what to get.

    Just returned this bad boy after one day. Charge says capacity is 100%, but the display after a full night charge only goes to 86%. Very heavy and I didn't like that it feels like it takes forever and a day to charge to 86%. I also do not like getting robbed out of 14% battery charge capacity. I also did not like that after I read the reviews on this product, everyone is experiencing the same problems. This product needs to be pulled and perfected for re-release.

    This powerful powerbank is just the right size to slip into a purse. Ease of mind when the power goes out. Also great for long hiking trips. Plug in as your walking and ready to use in no time.

    Heavy, but ive only had to recharge it twice since ive brought it. Ive charged my phone 3 times using this and my Samsung back up battery. The Samsung backup battery charges my phone 1 1/2 times before i have to recharge it. But the Energizer backup battery last a long time between charges. Definitely woth the money!Also has different options for you to charge your device, type C or USB.

    I love this power bank. I have had it for almost a year and still charges all my devices. It takes 3-4 hours for a full charge, but I am able to charge two tablets, an Apple Watch and two iPhones multiple times. I will be purchasing more of these to have as an emergency back up.

    This battery pack is definitely worth it, I get 4 1/2 charges. It does take a while for the pack to completely get to 100%. But still worth it
