Joyzis BR300

 is the smallest transportable electrical power station I have reviewed. In accordance to my scales, the size is 5.77 x 5.63 x 8.89 inches and weighs just around 7lbs.

The BR300 is far less cumbersome to carry around with you than the

BigBlue CP500

 or the

Ecoflow Mini

 — but at a significantly lower cost position and will retain your units billed when out on the road.

Yet this compact energy station will provide power to up to eight products concurrently, such as the wi-fi charging, DC, and AC ports. The twin carrying handles fold down flat when not in use and deliver a flat floor keeping six consume cans. This surface area is also a wi-fi charging pad which is activated by the swap on the prime of the electrical power station.


  • Smaller and lightweight
  • Two lights
  • Wireless charging pad

Do not Like

  • Poor consumer documentation
  • Incorrect details on net web site
  • No Sort-C cable provided

There is the BR300, a electric power adapter and cable with a Variety-C plug, and a vehicle charging cable in the box. It is a shame that Joyzis does not provide a Type-C charging cable in the box.

Also: Most effective moveable ability station

The BR300 has a capacity of 296Wh, or 80,000mAh if you think of it in phrases of mobile product batteries. This signifies that it has 20 occasions far more battery potential than your 4,000mAh cellphone battery.

All of its enter and output ports are on the entrance of the product. There is a DC 12V port, a cable, a swift demand USB 3. port with two USB Type-A ports, one particular 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 wants to be utilized with a Sort-C 60W PD quickly cost cable.

On both ends of the device are lights. Just one light is fixed with an LED light-weight used for reading through or ambient lighting. The other is at the other conclude of the power station and offers a fixed light — a speedily flashing mild or SOS pulses.

The running buttons are simplistic. The key ability change on the still left and a looking at light swap followed by a electricity indicator.

This indicator has 4 LED lights that flash even though the unit is currently being charged and stay constant when the BR300 is fully charged.

When three bars are lit, the charger is 75% billed, likely to a 25% cost point out when one particular bar is lit. Subsequent to the indicator, there is a swap for the light-weight on the correct-hand aspect of the unit and an AC change.

The BR300 has an output of 3000W — be informed that there is no surge security on this battery. If you test to use an electrical product that has a startup surge higher than 3000W, then the BR300 may swap itself off to shield by itself.

I could not uncover any indication any place that the products has surge defense, overload safety or limited circuit defense. However, it does have overheat protection.

I applied it for about two hrs, charging all my equipment and using both of those lights. The onboard lover started out functioning and continued for 15-30 seconds to awesome the unit down and cycling periodically while the lights have been on.

The BR300 has no IP score, so be careful when utilizing it in dusty or damp regions (the user manual states that the solution have to not be utilized in damp spots).

Joyzis intends to offer you a photo voltaic panel to demand the BR300, but I did not get a panel to evaluate, and whilst this is described in the consumer guide, Joyzis stated that the solar panel is not still out there to purchase from its website.

I discovered that the BR300 will demand from flat in below a few several hours when applying the PD60W mains adapter.

It is a helpful small energy station at a rather small value. 

You do need to have to disregard the incorrect sizing and body weight information and facts on the web and consider a person of these out for oneself. It will continue to keep your equipment charged in an crisis, give you options for electric power shipping and will give you in excess of 10 hrs of mild when you will need it.
