The Grid Doctor 300 is a portable battery power station with a built-in LED light, charged from a wall outlet or from solar panels. It has AC outlets, a 12V DC port, USB-A and USB-C PD ports at 30W and 60W, so it can run phones, lights, small fridges and similar devices. It accepts two solar panels at once, though the second panel is sold separately. It suits campers, emergency preppers and anyone who wants backup power for small electronics; against rival stations it is a modest-capacity unit with a strong port mix rather than a whole-home backup.

The Grid Doctor 300 is a portable solar generator that provides power when the grid is unavailable, such as during an outage, an evacuation or a trip outdoors. It has AC, 12V DC, USB-A 3.0 and USB-C PD ports for phones, mini-refrigerators and other devices.
Inside is a lithium iron phosphate (LiFePO4) battery that can be cycled over 2,000 times. The generator can be recharged by solar, wall outlet, car socket, or a USB-C and power block pair. It can connect to two solar panels at once, and pass-thru charging lets you use it while it charges.
It starts with the press of a button. A display with icons shows the battery level, battery life, and watts in and out. The compact cube shape has a collapsible handle for carrying, and units can be stacked on top of each other.
