Welcome to Alta Devices' battery life extension calculator tool. With this tool, you can quickly calculate how much extra battery life you can expect to get on a device with Alta's mobile power technology integrated. By choosing your device and type of user, you can see how much additional energy Alta can bring you.
If you want to get more detailed, simply enter the total capacity of your battery (in Wh), the amount of surface area you can cover with our thin and flexible solar material (in cm2), and how much exposure to the sun you typically get in a day. The tool will calculate the power generated from that sun exposure and report it as a percentage of your total battery capacity.
