    Very handy, instead of having to use a bulky cigarette lighter/power inverter. Just make sure you have the correct cables and you’re golden. It’s a little heavy, but worth it to me.

    Charges quickly but it is very very heavy. It’s not something a child can keep in their bag as a spare nor is it light enough to keep in your purse. I bought two and had to return both because of the weight.

    I wish it had a digital readout that told you the percentage battery life it has left, but it does have 4 lights to indicate level of charge remaining. Other than that it’s a fast charging high quality product and does a great job.

    A little on the bulky side, 1 lb. Will charge a phone 3+ times expect at least 12 hrs to fully charge back up, unless you have a good super fast usb charger.
