Which Voltaic products will charge a MacBook?

You can charge a MacBook from any of our solar laptop chargers including the Fuse 10W, Array, Generator, Arc 20W Solar Charger Kit and the 17 Watt Kit. See the complete list here.

If you do not need solar power, and are just looking for backup power, you can charge your MacBook directly from our V88 Universal Laptop Battery.

How do I connect to my MacBook?

USB-C MacBooks: If you have a newer MacBook that charges from USB Type C, you can connect directly from our V88 USB-C PD laptop battery using the USB-C to USB-C charging cable that came with your computer. Once connected, simply press the V88’s Power Button to begin charging.

Non-USB-C MacBooks: For older MacBooks that don’t support USB-C charging, you’ll need one of our optional MagSafe adapters. This modified MagSafe cable is specially designed to fit onto our V88’s Laptop Output Cable so that you can safely charge your device from DC power.

To charge, first select the Voltage that best fits your laptop’s power requirements. To determine your Voltage, locate the Output Voltage listed on your MacBook’s certified wall charger (Bottom Left Image). Most MacBooks will either charge at 16V or 19V, we recommend testing at the lower Voltage first and bumping up to 19V if the MacBook does not start charging. Once your Voltage is selected, simply connect your MagSafe adapter to the Laptop Output Cable and plug into the Output of the V88 Laptop Battery (Bottom Right Image). Hit the Power Button to begin charging.

How well will my MacBook run from solar?

Generally speaking, the longer your MacBook runs when unplugged, the better experience you'll have when charging from solar. MacBook Airs are more power efficient than MacBook Pros. While both solar conditions and battery life can vary considerably, these are rough estimates of what you can expect from our laptop battery and solar chargers in good sun. We use Apple's specified runtimes, so if your computer’s efficiency has dropped over the years your "hours of runtime per hour in the sun" will go down.

1 Hour in Sun = X hours Runtime Time to Charge 100% in Good Sun (Hours)

Can I charge my MacBook directly from the solar panel?

Due to inconsistencies in solar intensity, we do not recommend charging your laptop directly from solar. For charging off the grid, use one of our solar laptop chargers and power your MacBook directly from our portable laptop battery.
