Now packaged with the popular Solar Charging case, the SteriPEN Adventurer lets you travel the world without lugging around a bunch of batteries. Solar Charging clamshell case pulls double duty, providing handy, secure storage for the purifier AND recharging its two CR123 lithium batteries. Adventurer purifier provides the same great water treatment as the original SteriPEN, but with a smaller size and even lower weight.
