    Works perfect for me, used it for two concerts so far! The first time I charged the device, it took a few hours to get to 100 but the battery is still at 90 since usage.

    Replaced an ANKER battery. Although this is quite larger, it was easy to use, reliable and performs its tasks reliably

    Power lasts for a very long time but I rarely can get it to rapid charge my phone. Works well in a pinch or when traveling.

    I bought this for my wife to charge her i-pad pro while she is on a trip. It doesn’t really charge it as much as it reduces the power drain while it’s being used. It does charge a phone decently. It takes a LONG time to charge this device.

    Good product. Didn’t use it immediately so it sat unopened. After 2 weeks I opened it and it had 80% charge on it. Took it to zero on charging iPad and iPhone for 3 hours then charged it. Give it at least 6 hours to 100% ( went to bed). Will be useful on vacation and areas with few docking options. Great investment. Go get one.

    This is a heavy battery, but it’s got enough power to keep my daughter’s phone charged all through the roadtrip. Only wish it could output at a higher rate, but for the price this is more than adequate.

    The only thing that I don't like from this charger is you cannot charge a device and charge the battery at the same time... but is very good and very durable.
