ZMI QB810 10,000mAh Power Bank is the smaller sibling of the ZMI QB820 20,000mAh Power Bank.
I bought it for CN¥89 (S$19) (excluding shipping) at ZMI official online store in T-mall during their 12/12 sale. The usual price is CN¥99 (S$21).
It measures 127 x 69 x 12.7mm and weighs 177g.
There are two input ports, which means you can charge the power bank either with micro USB or USB-C. The USB-C port is NOT bi-directional, so it can only be used to charge the power bank.
The USB-A port supports Qualcomm Quick Charge 2.0 (QC2) and can output 5V/2A, 9V/1.6A or 12V/1.2A.
Unlike the bigger sibling, QB820, the USB-C port on this power bank does not support USB power delivery.
It also does not support pass-through.
Thank you for the review.
The QB810 does support a reduced version of so-called pass-through. To make it work, please make sure
1) the two cords (from wall adapter to the battery pack, and from the battery pack to the device) are short enough to avoid excess voltage drop.
2) the AC adapter is powerful enough to power both the battery pack and the device. For example, a 5V/2.4A iPad charging brick is preferred over a 5V/1A iPhone cube plug.
