Cygnett 6000mAh USB-C Power Bank
Verified2 reviews
Didn't last the distance – In the time this was functioning properly I couldn't have been happier with it. It charged my iPhone 7 Plus within half an hour (from memory), with the % level on the Power Bank dropping by about 1% for every 1% the iPhone battery level rose. But after about two years, it quickly failed. After charging the power bank to 100% and attaching it to the phone, it "died" in a hurry. Show details
Swollen battery cell – I actually quite like the functionality and size/weight of the product, but the battery cell in mine (purchased Aug 2018) has swollen considerably, so I doubt the product is still safe to use. I've also noticed it randomly stop supplying charge before the device is fully charged (but I've noticed this with other power banks I've owned too).
