The days of having to lug around heavy lead-acid batteries are gone, and that's cause for celebration around our office! Thanks to Lithium Ion technology, batteries are getting smaller and more efficient. Introducing the Orion Dynamo Mini Lithium PowerBank, a Lithium Ion battery that weighs only 1.6 lbs!

This battery is perfect for any "on-the-go" astronomer, as well as hikers, campers, and anyone who just wants to enjoy the outdoors, but not be too far away from their electronic devices. It features a generous 74.88 Watt-hour battery capacity (20,800mAh at 3.6V) and includes two USB ports as well as a 3-prong AC outlet. By using the two USB outputs, you can charge two phones, tablets, or any other USB powered device simultaneously with a max output of 2.4A per USB port. And if you have an AC device that needs power, the 85W continuous, 100W max AC port provides that extra power boost you need. 

Outdoor enthusiasts will especially love the small form factor. The Dynamo Mini is just 6.9" x 4.4" x 1.4" on a side. Now you don't have to worry about packing all your gear and wondering how to carry a large and heavy battery with you. At less than 1.5" thick, the Dynamo Mini will fit into your backpack, so you'll always have power available for your phone, camera, and all other powered accessories you've brought along. 

And of course, if you have a computerized telescope with an AC adapter, the Dynamo Mini Powerbank is just the accessory to have on hand to keep your setup lightweight and portable. It's even small enough to sit on the accessory tray of many telescope tripods. This is by far the most convenient battery we've offered, so whatever outdoor activities you enjoy, make sure you include an Orion Dynamo Mini Lithium Powerbank to keep all your devices running!
