Solar charging clamshell case pulls double duty, recharging the included double-cell rechargeable CR123 lithium battery and providing handy, secure storage for the purifier.
If there is one disadvantage to the SteriPen, it could be that the SteriPEN runs on batteries. While we recommend rechargeable batteries, there is another environmentally friendly solution: the SteriPEN charging case. With this solar charger, 2 CR123 rechargeable batteries can be charged which can run the Adventurer, Traveler or Journey.
Simply clip the charging case onto a backpack or set it on the ground and aim it towards the sun to recharge the double-cell battery; empty charging case weighs 6.8 oz.
Solar panel recharges 1 double-cell battery in 2 - 5 days, depending on solar conditions; battery can be recharged via the included plug-in power adapter in 4 - 6 hrs.
Included are 2 Lithium batteries (CR123), an 110V/240V power supply and a Neoprene cover
