Screens and mixers want mains power, and the best karaoke spots — a yacht deck, a garden, a beach terrace — rarely have it. The Delta 2 is the silent fix: 1024Wh of battery behind 1800W of AC output, with four sockets plus USB-C and USB-A, running a TV, a mixer and a row of phone chargers all evening without a hum. It is the quiet fourth member of our Yacht Karaoke setup.
Back at a real socket it recharges to eighty percent in about fifty minutes, so a lunch stop in a marina resets the whole evening. Twelve kilos, one handle, no petrol, no fumes — welcome in places a generator would never be allowed.
Who it’s for
Charter groups, off-grid villas and garden parties where the extension lead cannot reach.
When to skip it
- The whole rig is already battery-powered — a Soundboks with the tablet station runs an evening on its own; take the Delta 2 for multi-day trips.
- A villa with sockets everywhere — put the budget into lighting like the battery uplighters instead.
In the rental
Power station, AC charging cable, USB leads, quick-start card.
