You can charge a MacBook from our: Fuse 10W, Array, Generator and 17 Watt Kit. See the complete list here.
If you do not need solar power, you can just use our V88 Universal Laptop Battery.^back to top
All MacBooks connect to their power cord via a magnetic connector called a MagSafe. Voltaic takes used MagSafes from MacBooks and reconfigures the end so that they fit with our battery. These are not fancy looking, but they are functional. Set the Voltage on the V88 to 16V if the AC Charger that came with your MacBooks gives an output of 16.5V or 14.5V (MacBook Air). If your AC Charger outputs 19 - 20V set the Voltaic Battery to 19. Then just connect the DC Output cable into the battery, then connect the optional MagSafe to the cable and your MacBook.
For USB Type-C MacBooks, simply use your standard Apple USB-C to USB-C cable and connect to the USB-C port on our V88 laptop battery.
In June 2012, Apple introduced a new line of MacBooks which have a slimmer MagSafe design called "MagSafe 2". We have reconfigured MagSafe 1 (pre-June 2012) and MagSafe 2 (post-June 2012) adapters available.
If you already have a MagSafe 1 adapter, you can also modify it with Apple's MagSafe to MagSafe 2 Converter for about $10. This fits right on the end of our Reconfigured MagSafe or Apple's Airline adapter. Here's a closeup of the adapter and how it looks connected to the new MacBook 13" and our Reconfigured MagSafe.
There are three different types of MagSafe adapters. Some pre-June 2012 model MacBooks and MacBook Pros have connectors (the MagSafe 1 adapter) with right angle instead of straight-on connections, in part to accommodate the thinner profile of those MacBooks. If you use our optional MagSafe adapter it is likely that it will have the straight-on design. It will still work with your MacBook, but you may have to lift your MacBook off the ground an inch or so.
In the pictures below, the adapters on the left are both "MagSafe 1" and the thinner, silver adapter on the right is "MagSafe 2"
The 15-inch MacBook Pro retina is the most power hungry of all the MacBooks. It will always charge from our V88 battery when off. If it is running while charging from our battery, it may cause the battery to go into over-discharge protection. If that is the case, connecting the battery to a power source like a solar panel in the sun or an AC charger will reset the battery.^back to top
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 you are getting less than that, 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)|
|MacBook Model||MacBook Battery Capacity (Wh)||Apple Stated Runtime (Hours)||Times Charged from Voltaic V88 Battery||10 Watt Systems||17 Watt Systems||20 Watt System||10 Watt Systems||17 Watt Systems||20 Watt System|
|MacBook Air 13"||54.4||12||1.1||0.9||1.5||1.8||13.6||8||6.8|
|MacBook Pro 13"||54.5||10||1.1||0.7||1.3||1.5||13.6||8||6.8|
|MacBook Pro 13" w/ Touchbar||58||10||1||0.7||1.2||1.4||14.5||8.5||7.3|
|MacBook Pro 15" w/ Touchbar||83.6||10||0.7||0.5||0.8||1||20.9||12.3||10.5|
We do not recommend connecting the solar panel directly to your MacBook. Use the solar panel to charge the Voltaic battery and the battery to charge your MacBook^back to top
It is! We help your old MagSafes have a second life as part of a solar charger and give you $10 in return. Email us at support and we'll send you our shipping address. Please also include your PayPal address for payment along with your MagSafe.
Please make sure your MagSafe is in good condition before shipping. If it is dark brown/burnt on one of the pins, the adapter is fried and we won't be able to use it.^back to top
