Power station. 300w


By Joe on May 13, 2021


I’m a camping enthusiast. I’ve used various power stations, and so far, this power station is my favorite one among those of 500Wh (such price as well). The dual charging is fast. And it supports 18V / 300W solar charge(I used my 120W foldable solar panel). It reached the rated power of the panel.

I’m also satisfied with Ecosonique for the following features:
1.It has a solid case. I love its appearance of the bright orange. It touches nice of the rubber cover on the DC12V port. And it’s easy to open and cover back it. Rubber pins and handles are also ergonomic. It feels good when you hold it, and it doesn’t rattle.
2.It has separated buttons to switch the AC and DC ports. All the USB ports are plug-and-play ports which is perfect for sleep, and it won’t waste any power when it’s not needed.
3.It has the pass-through tech which means it can be charged in and out at the same time. That’s good. But I checked the Q&A and it’s not suggested by the manufacturer cause it might damage the power station itself.
4.It has the upgraded fast charging USB-C port and actually works for 100W as described. My iPhone 11 can be full charged quickly.
5.The back light is very large and not dazzling, with four pretty useful levels. It can illuminate my whole bedroom evenly. Pretty utility.
6.The fan is very noiseless. The device didn’t turn very hot while using, so everything they did for the heat dissipation solution worked well.
7.It came with a DC5521 cable of good quality and a car charger (not tried yet). It can be charged quickly by the AC adaptor.

It’s glad to share my experience. It deserves to be recommended. I guess if it’s maintained in a normal way , it will last working for more than 500 times. It seems very hard to be beaten for its very lightweight (about 7 lbs and compact), exquisite structure, reasonable price and fully functions. It would be great to keep it home in case of power failure. It would be great if Ecosonique could give away a customized storage bag to buyers.
