But I checked the battery and it uses 2 BIS approved 5000mah batteries for the 10K. Although some said this has QC3, I tried it with 2 QC2 phones and a USB-C fast charging phone and it only charged them at 10W and not 18-25W which means its 5V 2A charger. Still charges most phones in 90-120 mins.. But what I liked was the size and weight.. Its far smaller than other 10K and also weighs less. They also had the 5K PB and that as what I looked at originally.. But this definitely is more than a 5K PB as it still shows 2 bars after fully charging a 3000-4000mAh phones.. Seems to work like the other 10K PB's I have..
The USB-C port is ONLY for charging.. I checked and it dont put out any power so connecting it to the phone using that power means it will drain the phone and charge the PB.. This might be a software issue as USB-C ports can be used for many things by just software.. It also dont come with a USB-C cable.. So its a useless feature. Should have provided the USB-C cable with it since we are paying more for the USB-C port version of this.
