Partial failure after a few years

I have owned the 45W version of this power bank for a few years now with very little use.
It partially failed on me when I needed it the most, out on a remote multi day hike.
Using USB-C port, when it dropped to 2/4 power level, it would only charge my iPhone 15 for a few seconds at a time. But it was fine to charge my watch.
So I had to keep pressing the power button every few seconds to keep restarting charging.
Eventually after half an hour of this, my phone gained 10% and the power bank dropped to 1/4 power, at which point it resumed normal charging.
I believe this device is too complex for it's own good with the same USB-C port atte...view more

Great Capacity and Power Output.

Perfect for my school laptop which can never last the day. Powerful enough to charge my laptop and also keep my mates laptop charged at the same time if they run out as well.
Great solution when it's hard to find a power point in old school classrooms. I don't take my power adapter to school anymore, just this power bank.

Bulky but fast charging

Pros: Fast charges my phone and bought it on sale.
Cons: It’s too bulky and heavy. There are no button to turn it on or off. You have to rely on the blinking color indicators and what they are meant for.

Can't charge because there's no wall plug

Stupid product delivery because they don't supply a plug to charge, then I plugged into the laptop to piggy back charge but instead of charging it discharged straight off the bat which against the start up procedure. So probably ruined the device already.
