The LR40 Rechargeable Multifunction Lantern by Nitecore
The multifunctional LR40 lantern provides illumination with four different modes, including warm ambient lighting, and doubles as a power bank to charge your phone via its USB-A output. Its stable base allows it to be placed on a picnic table, for example, while its metal loop makes it easy to hang wherever needed. Equipped with a built-in 4000mAh battery, the LR40 is rechargeable via USB-C and offers up to 65 hours of runtime, equivalent to about 8 nights of use. Brightness levels can be adjusted gradually by rotating the lantern’s head cap in either direction. With its retro design, the LR40 is perfect for camping, off-road adventures, or even in your backyard.
