Amazing Power Station


By Chia Seed on June 16, 2021


It’s been a while since I needed a portable power bank but I really needed one this past trip. This power bank did exactly what I needed it to do it powered my portable car fridge via the AC adapter as I didn’t want to tax the battery of my car.
Before my trip I plugged it in overnight so by the morning it would be fully charged

After we parked and set up the tent I used the power bank to power a LED lantern and small fan.

I didn’t need to use the built in light as I didn’t offer the same converge as my lantern did but it’s a good emergency light in case I need it

I really like the fact that it has so many outlets for my electrics and appliances to be used simultaneously.
For example in the morning I was able to power an electric griddle while also powering a coffee maker!
It’s a little on the heavier side but it’s built so strong that I hardly notice. To me it feels like a big lunchbox.
There’s a little groove/slant under the handle which is great as I can leave my phone in that space to keep it safe from getting stepped on and it’s easy to get when someone calls.

It really helps me find the power bank even in the dark because the yellow really stands out so I’m glad it’s not all black. The bottom has these nice padded legs to keep scuffing to a minimum and to give it more traction.

Giant portable power bank


By Dennis on June 10, 2021


I got this to power my 110 gallon aquarium which uses a 300w heater. Most power bank if this size can only supply 250w to 300w peak output, but this one can output 500w with 1000w peak! It’s by far the highest output in this price range.

The cool thing about this power bank is the LED display. You can see the percentage of the battery left. It’s a huge improvement over the 4 led light gauge that some power station have. This also provide insight into how long it’ll be able to power the devices given the current wattage draw.

I drained it to 5 percent today from full because i was installing solar panels and the power had to be turned off for 5 hours. I power my iMac for the entire time without any issues. The fan automatically turn on once awhile to keep the unit cool. I was able to work without any interruptions.

Because the gauge shows the draw wattage, I’ve also been plugging in random appliances in my home to get a better sense on how much they consume in passive/off mode. I ended up disconnecting one of my old school speaker because it was drawing close to 20w in passive mode. It’s called vampire draw and it’s a waste if the device is not in use. So unplug them.

Powerful power station


By Mac on June 6, 2021


This is a very powerful and excellent power station. It is lightweight compared to other 500w power stations I have purchased. It has connections fir several different types of plugs USB, USB-C, regular outlets, cigarette lighter 12v. It also has an input for solar panels. It plugs into the power station and charges very quickly. It also has a built on LED light which is great for when the power goes out. We love having this for camping and emergencies.
