What Voltaic solar chargers will power my tablet?

All of our solar chargers will power tablets that charge from a USB cable including: iPad (any version), Samsung, Kindle Fire, and Nooks. The larger the system, the faster your tablet will be charged. Our solar laptop chargers are needed for tablets that are not powered by a USB cable including: Acer Iconia Tab, ASUS Transformer, Microsoft Surface and Motorola XOOM. We go into more detail below.

How does it work?

 

1. Charge Voltaic Battery

Charge-Voltaic-Battery

Charge up your battery from the sun, an AC outlet or car charger socket.

2. Connect Tablet to Battery

Connect-Tablet-toBattery

Use the USB cable that came with your device or use one of our adapters to connect from the battery to your tablet. You can do this at the same time you are charging the Voltaic battery.

3. Charge Tablet

Charge-Tablet

Your tablet will charge - with some of our batteries you may need to press the Power Button to activate the USB Output.

How long will it take to charge my tablet?

When charging from our battery once it is full, your tablet will charge at about the same rate as from your wall charger. The time required to collect that energy from solar depend on the capacity of the tablet's battery, the size of your panel(s) (in Watts), the weather (sunny/cloudy), shading on the panel(s), and the angle of panel(s).

On a sunny day with the panels outside, unobstructed, and facing the sun, here's about how much run time you can expect from your tablet for each hour in the sun.

Number of Minutes Run Time per Hour in the Sun based on Panel Size (Watts)

Do I need any extra adapters?

If your device charges from a USB cable no (except for the Galaxy Tab), just use the cable provided by the manufacturer. The adapter for the Acer Iconia Tab is also included with all our laptop chargers. You will need an optional adapter if you have a XOOM, ASUS Transformer, or Galaxy Tab. For the Microsoft Surface, we have an option where you can build your own cable.

I don't want the solar panels. Can I just get the battery?

Yes, you can get our V15, V39 or V70 batteries by themselves. Here's approximately how much of a charge they will give each tablet. These are estimates based on testing many of these tablets.
