The Joyzis BR300 is the smallest portable power station I have reviewed. According to my scales, the size is 5.77 x 5.63 x 8.89 inches and weighs just over 7lbs.
The BR300 is far less cumbersome to carry around with you than the BigBlue CP500 or the Ecoflow Mini -- but at a far lower price point and will keep your devices charged when out on the road.
Yet this compact power station will deliver power to up to eight devices simultaneously, including the wireless charging, DC, and AC ports. The dual carrying handles fold down flat when not in use and provide a flat surface holding six drink cans. This surface is also a wireless charging pad which is activated by the switch on the top of the power station.
- Small and lightweight

- Poor user documentation
- Incorrect details on web site
- No Type-C cable included
There is the BR300, a power adapter and cable with a Type-C plug, and a car charging cable in the box. It is a shame that Joyzis does not provide a Type-C charging cable in the box.

The BR300 has a capacity of 296Wh, or 80,000mAh if you think of it in terms of mobile device batteries. This means that it has 20 times more battery capacity than your 4,000mAh phone battery.
All of its input and output ports are on the front of the device. There is a DC 12V port, a cable, a quick charge USB 3.0 port with two USB Type-A ports, one 110V AC output and a DC port in and out.
There is also a USB Type-C port which is a PD 60W port -- this needs to be used with a Type-C
