USB power bank with red LED flashlight

is back in stock at bargain price

With the Explore Scientific USB Power Bank with Red LED Flashlight, you will have power to spare in the field for your telescope mount, smart devices, cameras and more.

Slightly smaller than a building brick and weighing only 1.4 pounds, this reliable rechargeable Lithium-Ion battery has a capacity of 8300 mAh with an output of 12v that connects to a supplied power cord with spring-loaded power plugs with 5.5mm x 2.5mm to 5.5mm x 2.1mm connectors. The 5v output from the USB port can power your devices with a standard user-supplied USB cable.

The soft deep red glow from the LED flashlight lets you see under dark starlit skies without ruining your night vision as you make adjustments to your equipment, read star charts, or locate that small telescope part you dropped in the grass.

The unit has a rugged rubber covering protects the battery from minor impacts, a five level indicator that shows power availability and a convenient attachment point that allows you to hang the battery near your equipment.

Aside from use on the star party field, the USB power bank is also a great option for situations ranging from off-grid camping to power outages.
