    We took this with us on our trip to Disney. We all used our phones frequently throughout the day. It was perfect for everyone to get a boost when needed. It also shows the percentage left on it, which was very useful in knowing when we had to charge it

    This a great battery pack for recharging phones and tablets. It even has enough power to run my motorized lazy susan tray. I recharge it using a solar panel during the day and then recharge several devices during the evening/ night. The digital power readout is nice.

    This is a horrible charger. I got it thinking it would be faster and multicharging. It only charges one thing at a time and only with the cord it comes with. It weighs so much. It takes forever to charge. It's a paperweight on my desk. I use my other power bank which weighs much less and can charge more than one thing at time while being held together by tape and rubberbands.

    Great Battery Life About a day of charging last me 5 full charges between two days on the IPhone. Only downside I had with this is the time it takes to charge full. It's about a full day

    This Battery was so useful, it’s very slow to charge, but lasts for hours once it’s powering your object. This went through TSA 6 times and they never ask about it.

    Great power bank to carry around in case you are not near a outlet for charging. It's a little bulky because I wanted one with a larger battery for charging multiple devices and it easily handles it.

    The Energizer Max power portable battery is phenomenal. I bought this during a power outage and was so glad to have something that was already charged & ready to go to keep me going until the power was restored. It recharges faster than expected. This battery is so good that I bought 4 more for my family members & neighbors so they too could have peace during an outage.& to have whenever it’s simply impossible to get to a wall outlet to charge gadgets
