Voltaic Solar Charger Backpacks: Losing Battery Power On Kili Is Now A Thing of the Past

Mark Whitman

Using electronic devices on mountains for extended periods of time has always posed problems as battery life is often limited.

Fortunately brilliant companies like Voltaic Systems have over the past decade or so develop solar charger solutions that are affordable, practical and actually look pretty slick!

Below is an overview of their new product, the Arc 10W Voltaic Solar Charger.

Voltaic Systems

Voltaic Systems is an American company founded in 2005 with a mission to develop energy solutions using environmentally intelligent design. Over the years they have launched many awesome products, but they are best known for their Voltaic Solar Chargers.

Their product range includes Voltaic Solar Charger Backpacks, Voltaic Switch Solar Bags, USB Battery Packs and a funky gadget called the USB Touchlight.

Arc 10W Solar Charger

There most recent addition, and the product that I think is perfect for Kilimanjaro, is the Arc 10W Solar Charger which comes with a universal attachment system that connects securely in seconds to backpacks and bike racks.

For the same weight as its 6 Watt predecessor, it also features 10 Watts of rugged solar power, a 15 Watt-hour universal battery, and convenient storage for a tablet, smartphone and charging cables.

Designed for modern adventurers, the Arc 10W provides up to 80 minutes of runtime on an iPad Mini, or other 7” tablets, for every hour in the sun. It will also charge smartphones, GoPro cameras and other USB devices.

Here’s a brief product overview

10 Watts of Power for Fast Charging

Integrated into the front of the Arc 10W is a rugged, waterproof 10 Watt solar panel. Charge times vary by device, but these high-efficiency monocrystalline cells will recharge a typical smartphone in under four hours. The panel is built to withstand the abuse of everyday use. The cells are encased in a clear, UV and scratch-resistant coating, and backed by a rigid aluminium composite material.

High Output USB Battery

The included V15 USB battery stores power so the Arc 10W can charge devices anytime. The battery has 15 Watt-hours of capacity, enough to charge an iPhone 1.7 times and an iPad Mini 2/3 full. For more battery storage, the 39 Watt-hour V39 battery is available as an optional upgrade for $39. Both batteries can be charged from the solar panel or any USB port.

Universal Attachment System

The Arc 10W is designed to attach onto technical backpacks, panniers, MOLLE systems and almost anything else via its flexible buckle and strap attachment system.

Room to Store and Manage Electronics

The Arc 10W has wire channels to deliver power throughout the bag. The case has mesh pockets to store cables and phones and a sleeve to fit up to a 10” tablet.

Pricing and Availability 

The Arc 10W is available on Amazon.

Key features and specifications of the Arc 10W include

  • 10 Watts of solar power (panel available in silver or charcoal)
