What's the best solar charger for Android phones?

How fast can I charge my Samsung S5 (or other Android phone) from solar power?

The power banks included with our solar chargers, power phones at the same speed as your wall charger. The time to charge your phone will vary based on the Wattage / size solar panel, the capacity of the battery in your smartphone and how sunny it is.

How do I connect my phone to the solar charger?

Use the USB cable that came with your phone or our included MicroUSB charging cable to connect to the Voltaic battery included with your system. If you purchase an Arc 10W Solar Charger, you can connect directly to the USB port on the front of the panel. This will charge up your phone in direct sunlight when outdoors.

Can I charge my Android smartphone with USB-C?

You can charge your Android phone with a Type C cable from the USB-C output on our V88 Battery Pack. This battery pack comes standard with any of our solar laptop chargers or can be purchased on its own.

Can I charge my phone and Voltaic battery at the same time?

All of our battery packs support pass through charging, so you are free to charge your device while the Voltaic battery is charging (either from solar or the wall charger). Stay connected while you charge and be sure to let us know what you’re up to… Instagram, Twitter, Facebook? We’re there too. Share with us @voltaicsystems

What if I want to charge my phone and a tablet and a GoPro...?

Our solar chargers power all USB devices. For smaller devices, any of our chargers will work. If you have a tablet, we suggest selecting a charger with a minimum of 6 Watts and 9 Watts for 10” tablets. For laptops, we recommend a 17 Watt or 20 Watt system.
