Like all Alza Power products, made in China. It stopped working after a short time.

It works
Better get another one from the range, this one is really basic for charging devices with slow charging

Already several times a product from the "Alza" brand that stopped working after a short time. After a short time, a fully charged powerbank stops responding and charging the mobile phone (shows 0/4 capacity LEDs). After trying to recharge it again, it surprisingly wakes up and shows immediately charged to 3 /4. this is the first time it's been like this and it's not the cable. For me again a disappointment, this was the last "Alzaprodukt". I see no reason to buy de facto electronic waste that I can throw away in six months.
compact
definitely does not correspond to the stated capacity

The power bank is just right for your hand, it's not heavy. It has a plastic non-slip surface, it is easy to hold. Charging two devices simultaneously works ok.

All ok, but it doesn't charge from USB-C with some (more powerful) chargers. Somehow it can't agree, if you use the very ordinary cheapest 2V charger then it works via USB-C.
Small
It works
Does not charge via USB-C port from the original Apple Macbook Air 2023 charger
