EnginStar 300W Portable Power Station with 60W Solar Panel: A Full Review

Waking up in the back of a Subaru with a dead phone and a deflated air mattress is a rookie mistake I only made once. Since then, I've kept a battery backup in the trunk. The EnginStar 300W unit caught my eye mostly because it bundles a 60W foldable solar panel for under $250, which is usually unheard of in this category. At 6.5 pounds, it's about the size of a lunchbox and fits easily behind the passenger seat. With a 296Wh capacity, it's not meant to run a microwave or a space heater. Instead, it handles the realistic off-grid basics: keeping phones topped up, running a CPAP machine overnight, and powering a 12V mini-fridge or string lights. I consider it a strong contender for the best power station for car camping simply because of the value and portability. The two 110V pure sine wave AC outlets are a nice touch for sensitive electronics like laptops, avoiding that weird buzz you get from cheaper inverters. Recharging via the included solar panel takes patience. Under direct sunlight, you might get a full charge in a day, but cloud cover slows things down drastically. I usually plug it into the car's 12V socket while driving to the next trailhead, which tops it off much faster. The build quality feels entirely plastic, so you don't want to drop it on rocks. But for keeping your essential gear running during a weekend in the woods without spending a fortune, it does exactly what it needs to do.
