The main drawbacks mentioned are its weight and size, which some customers find less convenient.

    Bit slow to re-charge. But once fully charged, can recharge many units before the battery is full drained! Very happy with this Unit! TY.

    This power bank weighs quite a bit at 22oz, so may not be for portable operation. However, for a standby power extender for multiple devices it’s exceptional. Plus, the fact that it can be charged quickly by a USB-C dual direction ports makes it versatile.

    I wanted the equivalent of this from anker but they just dont offer that here at best buy at this price point. As a total tech member, i got this for under $40 which is very good deal. Best bang for your buck!

    Excellent power bank! It does take a few hours to charge with a fast charger, but it also lasts for days depending on what you're charging. It is a little heavy but that would be expected from a 30000mAh battery.

    Worked like a charm overseas especially when you are in a remote area. A little bulky but well worth the extra needed space.
