Light, tough, portable
Posted by PeterFast delivery, good tech support, works as described. Remember, it is a little panel, needs “sun” to charge, not much use on a cloudy day

Awesome gear as usual
Posted by GooseI've been using various Voltaic backpacks and chargers since 2008 or so. They keep getting more useful and capable. The Arc 20 solved a particular problem for me: keeping an Internet hotspot going 24x7 at a remote cabin. The battery powered the hotspot in the evening and the panels charged during the day. Voltaic's gear worked as expected, which is to say always works well.

Best Solar Charging system "out There"...
Posted by ThomI ordered the ARC 20 kit several weeks ago...It is ...without a doubt...the best made..the best solar charging system available . I am a partially disabled Viet Nam veteran and ease of set-up and operation are critical to me...The ARC 20 system DELIVERS..!!! I only wish I had gotten an extra battery pack with my order....I will never forget the kindness shown me by Voltaic Systems...per extending me a military discount and for creating such superlative solar charging products. Best! Thom Mauck

Unbeatable for extended trips!
Posted by William MantaniThis is a must-pack piece of gear for me, for any extended backcountry trip. As a photographer it is very reassuring to know that you can have power anywhere you go! I never go without it! The weight to performance ratio is second to none! A+++!

Excellent product!
Posted by LizzieThe solar panel by itself is incredible. It's been charging the V72 through glass on a cloudy day. The kit is going to Haiti as part of the relief effort following the hurricane. We expect excellent performance.

Don't leave home without it
Posted by RZThe Arc 20 has been an invaluable piece of kit that has helped keep our equipment charged while working in the field for extended periods of time. We've traveled with the Arc 20 for several weeks while trekking through New Zealand and Tahiti and most recently on a month long cross country road trip. We’ve used it to recharge camera batteries, action cameras, laptops, phones, tablets and have even used it to power a 12 volt fan while camping in warmer weather. While on the road the solar panel lives on the dash of our van, ensuring our Voltaic battery is always topped off and ready to take with us. One of our favorite aspects of the solar panel and battery is it’s compact form and weight. The Arc 20 is very light weight and takes up so little room in our pack there’s no reason for us to travel without it. For us, having portable power is a must and although we’ve used other portable solar panel systems in the past, Voltaic has proven to not only be the most reliable but the slimmest and lightest weight on the market.
