    Although this charger charges my iPhone, iPad, and android devices, it is slow and I have to use my other USB cords to connect with it.

    The value is great- the only thing is its a little heavy and large- which is probably just the reality of a strong portable charger.

    Lots of power, but honestly it’s kind of bulky if you’re planning to walk around with it in your pocket.

    I have been using a 10k mAh Anker charger with Quick Charge 3.0 that charged my Samsung phone quickly. I chose this because I wanted a 2nd port and larger capacity. However, this 20k unit does not do fast charge for my phone even though it also has QC3. While still faster than other portables it is a slower than the 10k Anker. Otherwise it works well and the 2nd port is very useful.

    You can charge a few devices before needing to recharge it itself. However does not charge your devices very fast.

    It's a good charger but it's bigger than I expected. I thought it would be no bigger than my phone but it's much longer.
