Joyzis BR300 Portable Power Station review – Lots of power in a compact package

REVIEW – Camping. Backyard parties. Power outages. These and many other activities may require power for lights, speakers, music players, and who knows what else. You can run extension cords but they’re unsightly, people can trip over them, and in the case of a power outage, they might not even be an option. Enter the Joyzis BR300 Portable Power Station, a portable battery with a variety of output options to power all your devices.

What is it?

BR300 is a high capacity, portable battery which can be used to provide power to many of your devices, simultaneously, providing long-lasting entertainment or reserve power and lighting for safety purposes.

Design and features

The Joyzis BR300 Portable Power Station is a small battery, about the size of a motorcycle battery. There are two handles at the top which flip up to make it easy to carry the battery. There are two light sources–a spot light for use as a flashlight or SOS light, and a flood light, usable for reading or general illumination. The top is flat to accommodate the Qi charging pad. There are rubber feet on the bottom to keep it from sliding around on the table or other surfaces you may put it down on.

Installation and setup

Setup of the Joyzis BR300 Portable Power Station consists of unboxing the power station and making sure it’s fully charged. When I pulled it out of the box, it was at about 3/4 capacity. Using the included USB-C power adapter, it took about 4 hours to fully charge. Subsequent charges with a 90W USB-C PD charger took about 6-8 hours to fully charge the power station from 0%. That’s pretty respectable for such a high capacity battery.

The front panel of the BR300 has four buttons: 1. Power On, 2. Reading Light, 3. Flashlight, 4. AC outlet. There is an additional button on the top of the unit to turn on the Qi charger. Also on the front panel is a four-LED display to show the charge status.

The Joyzis BR300 Portable Power Station has a total of 7 power outputs: 12V cigarette lighter socket, 3x USB-A, 1x USB-C, 5.5mm DC, and 110V AC. In addition, there is a Qi charging pad on the top surface, which supports 5, 7.5, and 10 watt outputs. My Android phone shows this as Fast Qi charging. There are higher wattage Qi chargers available, but 10W maximum output is still pretty good.

When charging multiple devices, which draws a decent amount of power, there is a fan that comes on to help keep the power station cool. It’s not really very loud–outside you probably wouldn’t even notice it–but if you’re inside, powering a laptop or iPad, while watching a movie, it would be noticeable, so you’ll want to place it behind a couch or chair or something to help block the noise. (Don’t place a blanket or other similar items over it because that would block the fan and potentially cause the battery to overheat.) The fan doesn’t always run; it likely only comes on when you’re charging multiple power-hungry devices, but it’s something to be aware of.

In testing the Joyzis BR300 Portable Power Station, I was able to charge my 16″ MacBook Pro with the 110V output and 12.9″ iPad Pro over USB-C for a couple hours and hardly depleted the battery. I even added my iPhone 11 Pro Max for a little while at the end. It still had more than half its capacity left after this test. This led me to test how many devices I could simultaneously charge and I was able to get to 7 devices–MacBook Pro from the AC outlet, iPad Pro over USB-C, Android Phone on the Qi pad, my son’s iPhone 11 through a cigarette lighter adapter,  a small Nitecore flashlight, my Samsung Galaxy Buds+, and an 18650 flashlight battery; the last three used the three USB-A ports. I also turned on the flashlight and flood light for good measure. I didn’t run this test for very long but I believe the power station would have enough capacity to charge all these devices from 0% and still have some capacity left over. 

The great thing about being able to use all these outputs simultaneously is that you’d easily be able to power a portable speaker, a phone playing music, some LED lights to illuminate the back yard, and even charge a few friends’ phones, late into the night, without worrying about running out of power before the party ends.

What I like

I like that this portable power station combines a high capacity battery, an AC inverter, a flashlight, several outlets, a Qi charger, and two different light sources, into such a small, lightweight form factor. The fact that it can use all of these features simultaneously without limiting how many devices you can power at once is a great benefit.

What I’d change

It would be nice to have more USB-C outputs since so many devices use that connector now but otherwise for the price, the size, the capacity, and total number of outputs, I don’t think I’d change much.

Final thoughts

If you need a lot of power in a portable package to power several devices at once, or just to provide long-lasting power for emergency use, you can’t go wrong with the Joyzis BR300 Portable Power Station.
