    Power lasts for a very long time but I rarely can get it to rapid charge my phone. Works well in a pinch or when traveling.

    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.

    I picked up the energizer 30,000mah powerbank because it was the biggest one in the store. It took a while to fully charge but it kept a phone charged for two full days with a little bunnypower to spare.

    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 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.

    The only thing that I don't like from this charger is you cannot charge a device and charge the battery at the same time... but is very good and very durable.
