Using the Voltaic V72 with other Branded Solar Panels…

The Voltaic V72 charges well from Powerfilm, P3 Solar, Aspect Solar, Goal Zero, and other popular solar panels in addition to the Voltaic packs and DIY modules. It can also be charged from the included AC charger before you head out.
The input connector on the V72 is a 5.5×2.5mm barrel. If no such output option exists for your panel, using the CLA (car cigarette adaptor) is a good alternative (most portable ’12V’ solar panels offer the CLA socket, and the V72 comes with the male CLA plug for charging from a vehicle)

Useful Tips
Try setting Voltage one lower than your laptop charger’s output first. i.e. if your charger says 19V, try 16V setting on Voltaic battery first. This saves power. The V72 battery will work best with smaller, more efficient laptops 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 19Volts. We recommend storing and charging the battery in a cool place.
If you don’t see the correct adapter for your device or cannot use manufacturer supplied USB cable (for handhelds only), contact us.
