In detail: Campingaz Powerbox Plus Electric Cooler 28L
Campingaz, a reference brand in camping gear, offers with the Powerbox Plus 28L a thermoelectric cooler designed for both mobile and stationary use. Its dual 12V (car socket) and 230V (mains) power supply lets you plug it into a car, campervan or home outlet, with both cables included.
Claimed performance reaches 19°C below ambient temperature, with 4 operating modes: Eco to save energy, Night for quiet operation, Max for peak performance, and Off. The 28-litre capacity holds up to six 1.5-litre bottles, a size suited to a weekend or an extended trip.
Two features set this model apart: an antimicrobial interior coating that limits bacterial growth, and a built-in battery monitor that automatically cuts power before excessively draining the vehicle's battery, a real plus for extended use with the engine off.
The Campingaz Powerbox Plus 28L suits anyone after a versatile, reliable electric cooler from a brand with decades of history in camping gear.

Our tester's verdict: Gilles Caron
Taken on several camping weekends and tested daily on the commute in 12V mode, the Powerbox Plus 28L confirms its versatility. Switching between mains and car socket needs no particular adjustment, a genuine convenience for anyone alternating uses. The claimed 19°C below ambient checks out under normal conditions, with a noticeable drop in performance during the most extreme heat, as with most thermoelectric coolers. Night mode proves genuinely quiet for use in a campervan without disturbing sleep. The built-in battery monitor prevented an issue during a long stop with the engine off, cutting power before the battery was drained too much. The 28-litre size stays manageable to carry thanks to its two sturdy handles. A reliable choice for anyone after a versatile electric cooler from a reference camping brand.
