REVIEW – We recently lost power for three days due to a big storm. Fortunately, a friend let us borrow a generator that saved all of the food in our fridge/freezer, and we used some small battery chargers for our phones. Since then, we’ve been thinking about a portable power option for our electronics, a fan or two, and possibly even our fridge. If you’re also looking for a small, portable power station for camping or power outages, the Coofly S600S power station is one to consider.
What is it?
The Coofly S600S power station is a 600W backup battery with multiple ports and outlets, and the option to add solar panels.

Design and features
We’re not new to power stations, we reviewed one earlier this year. The Coofly is less expensive and less powerful than the EBL station we previously reviewed. It takes about the same time to charge and is about the same size.
Setup
Setting up the Coofly S600S power station is self-explanatory. You just plug it into your wall, car charger or solar panel (120W solar panel not included). Ours came 70 percent charged.
A digital display clearly shows your battery percentage.
Performance
We haven’t had any power outages since I got this. But my son and co-reviewer is building a cabin in the woods with his buddies, and he’s used the Coofly S600S power station a lot. Primarily they’ve used it to charge devices. At most they had it powering a speaker and three phones (2 on USB; 1 on AC). Overnight, they used it to power a fan.
Our only complaint about the Coofly S600S power station is that it takes a long time to recharge. For example, Mason came home and plugged it in just after noon, exactly 12:10 PM (10 percent battery). By 4:28 PM it was only up to 28 percent; 5:40 PM it was up to 45 percent. When he needed to use it again, at 7:09 PM, it was only up to 69 percent.
As examples of chargeable devices, the manual suggests:
- USB output: smartphone, smartwatch, digital camera, e-reader, tablet
- 12V car charger outlet: light, car adaptor
- AC output: laptop, LED screen household appliances
In one full charge, the Coofly S600S power station can power:
- LED lights for 115 hours
- A laptop (9 times)
- A projector for 5.7 hours
- A fan (12 hours)
- An iPhone12 (50 times)
- A Nintendo Switch (36 times)
- A wall-breaking machine for 23 hours (I think they mean blender!)

What I like
- Easy setup
- Clear display, simple to use
What I’d change
- Faster charging time
Final thoughts
The Coofly S600S power station is a solid choice for backup power with multiple possible uses.
