This product is highly recommended for all users of rechargeable lithium batteries.  LiPo bags are a fire-safe portable container for use when charging your batteries.  LiPo bags are most commonly used for R/C car batteries, as a group they have been using lithium cells for quite a while. 

 

This is a heavy, quality bag with a velcro closure and smooth material interior.

Place your charger and battery inside the bag.  Run the cable out of the bag, and place on a fire-safe surface.  Furniture, wood floors and carpets are good examples of where NOT to charge your batteries.

The charging bag measures 7in x 9in.

 

A 1000mAh (XL) eGo battery and charger is shown for size comparison.  This should accommodate most charger/ecig combinations.

 

Under normal conditions, you should never need this product's protection.  Think of it like insurance, in the (very unlikely) event that an accident occurs while charging, you're covered.
