    Great for travel. Holds a long charge and can last for multiple uses until you need to plug it back in. It is a little on the heavy side but it's because it's a larger milliamp battery, meaning larger/heavier components.

    Great Capacity, Good Weight

    First large capacity power backup. So far, so good. Plenty of power to keep a couple of iPhones charged during long days at Walt Disney World. Disney WiFi is very useful, but is a battery killer. This made for a much better day. Form factor and weight make it easy to carry around.

    Let’s be honest, it’s basically impossible to live without a charged phone or electronic device these days… living in Florida, I purchased this to ensure I have the ability to charge my phone just in case of an emergency (family, friend, evacuations, emergency notifications). It’s also been essential because I work as a healthcare provider and need to be in contact with the hospital for multiple reasons. So overall, great to have!

    This works pretty good, but the irritating feature is that when I plug my phone to the charger, I have to remember to press the button on the charger too. Ideally, it would just start charging. I keep forgetting to do it from time to time, so my phone is not charging, as I thought it was.

    This is an excellent item, I love it; works great. I bought it because of power outages during high winds. It enabled me to have some entertainment, and I didn't have to sit in my car to recharge my phone. Sitting in the dark with nothing to do was no fun, so this item was a great comfort to me.

    Nice portable charger. Works well and am able to get several iphone charges out of it. We purchased it before a trip to Disneyworld (where you definitely need one) and could go a couple days before needing to recharge.

    Excellent fast charging for my Android phones/tablets and I can get at least 5-6 full charges out of it before having to charge it. Make sure you read the power output specifications since it can't support charging laptops that need more power.

    It works very well. The only issue is that it is extremely heavy, yet our teen g-daughter is okay with it. If I had purchased it for myself @ 60 y.o I would have had to return it, due to the weight it would add to my purse.

    I'm loving this power box. It's like having portable house current. I have a Belkin of similar capacity and capability; between the two of them I have nearly four days of power (if not, more). I can be places and use my devices, I'm loving it.
