Review on DieHard 71522 140W Power Inverter: Unleash Unlimited Mobile Power! by Eric Hartman

I bought this once on a trip to K-Mart (yes, you read that right K-Mart!). He, the packaging and the store are clearly relics of the distant past. The fan was noisy and noisy, the USB never worked, and the device charged at best twice as fast (randomly shutting down for no reason) and only under reduced load (*barely* 50-70W, nothing more). So ok, but nothing more. Back then I had it all and it worked for me in a pinch. But make no mistake, it's always been a piece of junk.
