Cygnett ChargeUp Boost Gen3 10,000mAh

Useless – This product was just a waste of time. Bought one, and it would not charge any device connected to it. Returned and got another one, which was flat when opened, and would not charge. So got a third one, and had the same issue as the first one. Returned and got a full refund. I will never buy a Cygnett brand again.

Worked once and failed – Bought for an overseas trip. Charged to 100%, did a test charge on my phone and a tablet with a USB C connector to ensure all ports worked before flying out. It never worked again. Would not charge anything, from any port. Carried it around as dead weight while traveling in Asia just to claim warranty on my return to Australia.
