The dad who already owns a deep-cycle battery and currently runs the camp fridge off alligator clips
What it is
12V battery enclosure with 2 USB ports, a 12V accessory socket, digital voltage display, weatherproof connections and a resettable circuit breaker.
Why we picked it
It turns a loose deep-cycle battery, which is a heavy acid-filled hazard rolling around a ute tray, into a safe sealed unit with fused outputs and a voltage readout so he can see the charge state before he is stranded. It is the cheap accessory that makes gear he already owns usable.
