Recharge your batteries anywhere in the world when you have the Solpro Tag Solar Charging Battery Pack. This device is the size of a credit card yet is packed with technology. Featuring high-efficiency solar cells and a Texas Instruments BLE chip, it uses next generation USB technology to power your device. Tag has an 1100mAh battery inside to gather solar energy. An hour of sun exposure fills the battery 10%. Or, you can use the included USB cable to charge with electricity. Just like a luggage tag, Tag easily attaches to your gear so it’s always in sight of the sun. In addition, Tag is designed to be future-proof. It features two USB-C ports for the latest devices. However, it also comes with a USB-A adapter to also work with any of your legacy cables. Tag also has TrackR integration so you’ll never lose it on your travels.
