Joyzis BR300 review: A portable power station for all your devices

Table of Contents


Joyzis BR300

 is the smallest moveable electricity station I have reviewed. According to my scales, the measurement is 5.77 x 5.63 x 8.89 inches and weighs just about 7lbs.

The BR300 is significantly much less cumbersome to carry all-around with you than the

BigBlue CP500

 or the

Ecoflow Mini

 — but at a significantly reduce value position and will maintain your units billed when out on the road.

Still this compact power station will supply electricity to up to eight gadgets concurrently, including the wireless charging, DC, and AC ports. The dual carrying handles fold down flat when not in use and give a flat floor keeping six drink cans. This area is also a wireless charging pad which is activated by the swap on the prime of the electric power station.

  • Lousy consumer documentation
  • Incorrect particulars on internet web page
  • No Kind-C cable provided

There is the BR300, a ability adapter and cable with a Style-C plug, and a automobile charging cable in the box. It is a disgrace that Joyzis does not give a Type-C charging cable in the box.

The BR300 has a potential of 296Wh, or 80,000mAh if you feel of it in conditions of mobile device batteries. This indicates that it has 20 occasions extra battery capacity than your 4,000mAh cellular phone battery.

All of its input and output ports are on the entrance of the unit. There is a DC 12V port, a cable, a swift charge USB 3. port with two USB Style-A ports, a single 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 demands to be made use of with a Form-C 60W PD rapidly charge cable.

On both ends of the unit are lights. A single gentle is mounted with an LED light utilized for reading through or ambient lighting. The other is at the other conclude of the electric power station and presents a preset light-weight — a fast flashing gentle or SOS pulses.

The running buttons are simplistic. The main ability switch on the still left and a examining light-weight switch followed by a electrical power indicator.

This indicator has four LED lights that flash whilst the device is remaining charged and continue to be regular when the BR300 is absolutely charged.

When a few bars are lit, the charger is 75% billed, heading to a 25% demand point out when just one bar is lit. Next to the indicator, there is a change for the gentle on the suitable-hand side of the device and an AC swap.

The BR300 has an output of 3000W — be mindful that there is no surge defense on this battery. If you try to use an electrical machine that has a startup surge increased than 3000W, then the BR300 could possibly switch alone off to protect by itself.

I could not come across any indication everywhere that the products has surge defense, overload safety or shorter circuit security. Nevertheless, it does have overheat protection.

I made use of it for about two hours, charging all my units and using both of those lights. The onboard lover started off jogging and ongoing for 15-30 seconds to great the device down and cycling periodically whilst the lights have been on.

The BR300 has no IP ranking, so be careful when utilizing it in dusty or moist areas (the user guideline states that the item need to not be utilised in damp locations).

Joyzis intends to provide a photo voltaic panel to cost the BR300, but I did not get a panel to overview, and though this is mentioned in the consumer tutorial, Joyzis reported that the photo voltaic panel is not nevertheless readily available to get from its web site.

I identified that the BR300 will cost from flat in underneath 3 several hours when making use of the PD60W mains adapter.

It is a valuable minor power station at a quite very low expense. 

You do will need to overlook the incorrect size and excess weight information and facts on-line and check out a single of these out for you. It will maintain your devices billed in an crisis, give you possibilities for electrical power shipping and delivery and will give you about 10 several hours of light when you have to have it.
