Reviews & Ratings
Translation: machine translated
- Capacity exceeds expectations
- Digital percentage display for charge level
- Somewhat high charging time
- Performance only moderately good
Among the 10,000 mAh power banks, a Varta model with wireless charging wins the test, while Xiaomi convinces with high performance and short charging time among the 20,000 mAh power banks. If you want to buy a really powerful power bank, it's best to go for the Anker 737 - it charges in record time, but is quite expensive...
