Back in the day to get power in the field you had to lug an array of heavy lead-acid batteries to remote locations. What a hassle! Thanks to Lithium Ion technology those days are way behind us! Batteries now are smaller, lighter 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, and still maintain extensive field use of 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. Need to power an AC powered device in the field? The 85W continuous, 100W max AC port allows you to do just that!

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 or laptop case, so you'll always have power available for your phone, tablet or laptop, and all other powered accessories you've brought along.

As an added bonus, if you have a computerized telescope with an AC adapter, the Dynamo Mini Powerbank will power your setup through the night. Lightweight and portable, it's even small enough to sit on the tripod accessory tray or rest on your Dobsonian base. This is by far the most convenient battery we've ever offered, so whatever outdoor activities you enjoy, make sure you include an Orion Dynamo Mini Lithium Powerbank to keep all your devices running!
