    Great powerpack, charged my Galaxy S10+ 2 full charges. It's a little heavy but worth the buy. Quick to charge.

    This charger is a great thing to have. It's nice to be able to charge without having to be plugged into the wall outlet.

    Really good. Came already charged. I bought it maybe like 3 weeks before i had to actually open the box and use it. And it still kept a charge.

    This is my first portable battery charger, so I cannot compare it with others. I can say that at this point in my ownership, it is retaining its charge well with the passage of time, and that it does a good job of charging my various devices (both slow and fast charging.) For output comparison, it has charged my large cell phone (4000mAh) from 20% to full about 4.5 times over the course of 1 month before it ran out of juice. (I bought during BB's half price sale, so my "value" assessment is probably too favorable. :-) )

    Exactly as advertised. Can charge two phones two to three times each. Heavy, but to be expected for all the charges it provides.

    I use two phones for work and sometimes they can be running with the screen on for 12 or more hours a day. As a home inspector, I'm moving all over the place, so I can't just plug my phone into an outlet all day. This portable charger allows me the flexibility to move around while getting the power that I need. The other thing that I like is the turbo charge feature for when I need something charged as fast as possible. This also has a trickle charge USB port for when I just need a steady stream of power.

    Some use these as a 'just in case' tool when your device runs out, but I've found that this is really helpful to just give my devices that extra boost. Especially at night, where I don't have a plug near my night stand. I use this to charge my phone over night. The fast charge really does charge fast. I get a lot of charges out of this before it starts to get low. It does take a while to recharge, so don't be in a hurry and just plug in it somewhere when not using it.
