Manufactured by VLITEX, the smartphone battery bag is built from special glass fibre fabric with a shock-absorbing 3mm HT mat and HT polymer coating; it withstands temperatures up to 1,000°C, reducing smoke and heat development while staying shockproof. 

It also provides high burst resistance for explosion protection, high cut protection and low electrical conductivity. An integrated metal ring lets it clip onto a keyring or bag, and it's equally useful for keeping small documents or USB sticks protected. German-designed, made in Europe. At just 13cm x 22.5cm x 2cm and 0.12kg, it goes wherever your devices do.
