  • Light, tough, portable by Peter (on 10/2/2018)
    Fast 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 by Goose (on 9/26/2018)
    I'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"... by Thom (on 5/13/2018)
    I 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! by William Mantani (on 9/8/2017)
    This 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+++!
