Battery (Terratek) Pack USB Addon

was in the garden and my portable speaker ran out, i Have 5 of these battery packs as i bought all the same devices (strimmer, Hedge Trimmers and leaf blower) and i though could i use them to charge my speaker.

10 mins later i had bodged a passable cable solution but i wanted a modular answer

this is the first module

a USB charger

plans are for

A work light
deck light dock (so i just slip one of these in when we use our deck
12v cooler box adapter

hope you like the idea
