Useful Tips

Try setting voltage one lower than your laptop charger's output first. If this doesn't properly charge your laptop, then use the higher setting. (e.g. if your charger says 19V, try 16V setting on Voltaic battery first. It can save power if the laptop drops the voltage.)


The smaller and more efficient your laptop, the more runtime our battery will provide. To maximize runtime, change your power management settings to Maximum Battery Life & turn off WiFi.


Some laptops will run from the Voltaic battery with their internal battery removed. You should turn off your laptop before the Voltaic battery is fully drained to avoid crashes.


Remove the cable from your device before changing Voltage between 12, 16 and 19V.


We recommend storing and charging the battery in a cool place.


If you don't see the correct adapter for your device, please use the manufacturer supplied USB cable or please contact us via our Tech Support Form.


Compatibility

Our chargers are designed as universal chargers so this is a partial list of thousands of compatible devices. If you have a question about compatibility with your device or expected charge times, please contact us via our Tech Support Form.

Laptops

Apple: Pre-June 2012 requires optional reconfigured MagSafe 1 adapter or Apples' Airline adapter connected to our standard car charger socket. Post June-2012 MacBooks require the Apple MagSafe to MagSafe 2 adapter. See more about making the connection here. Dell: Newer Dell Ultrabooks use the optional 4.5x2.8mm adapter and will recharge from Voltaic's battery. Older Dell's may not recharge, but will run off Voltaic's battery. This means you should not run your Dell battery completely flat when planning to use an external battery. HP Business: HP Business Class laptops will require an optional adapter "7.4x5.1x0.6mm HP" here.
