This is the V250 Portable Solar Laptop Battery + USB-C PD by Voltaic Systems. One of the incredible line of solar batteries from Voltaic that powers your laptop, smartphone, GPS systems, drones, and just about any other small electronics. We’ve been carrying Voltaic equipment for over 10 years, and their quality & reliability stand-out against any other brands.
No inverter… this is all DC, and that’s a good thing. Inverters waste up to 30% of your battery power in creating the 120V household AC power that your device’s wall adaptor would just convert back to DC anyway. Stop wasting energy, and plug in directly to USB, USB-C with power delivery, or any of the multiple voltage settings this battery supports.
The V250 Portable Laptop Battery with USB-C Power Delivery is a workhorse for all day laptop and device charging. Compatible with most consumer laptops (including MacBooks with your USB-C cable or an optional adapter), smartphones, tablets, DSLR cameras, and consumer drones.

Solar Charging the V250
While you can always charge this from your wall outlet, or any USB-C PD port, the V250 excels at solar integration. Any solar module up to 50W (up to 25V DC) will work with the V250, and will charge from empty in a single sunny summer day.
Pass-through is the key here… charing from sunshine, or any other source, doesn’t mean you can’t plug your equipment into the V250. The battery system will prioritize your device, and only save any leftover charging power for itself. Operating just like any good off-grid solar system should.
