Xiaomi Mi Pro 10000mAh Power Bank with Two-Way Quick Charge
The power bank is 42% thinner than the original 10000mAh and it uses high density lithium polymer battery cells. The Xiaomi Mi Pro 10000mAh power bank comes with a USB Type-C port that can be used to char any mobile device or a Macbook. You can also charge the power bank itself with the USB Type-C port. Another exciting feature is the 18W two-way fast charging. This means that you’re able to charge the power bank and your device with fast charging technology. With an ordinary 5V/2A charger it takes ~6 hours to charge the power bank and ~3.5 hours with an 18W Quick Charger. The powerbank has the usual chipset and circuit protection found in other Xiaomi power banks from Texas Insturments. This offers 9 layers of protection including temperature protection, short circuit protection and battery overcharging protection. If the power bank didn’t have this kind of protection then it could easily overheat and explode. This is becoming increasingly common with generic and fake Xiaomi power banks.
