What this video covers

Anchored in Poole Harbour with a laptop battery dying mid-edit, Dave opens a parcel containing a BLUETTI Elite 100 V2 portable power station — a 1 kWh lithium-ion unit — and uses its 34% factory charge to finish the edit.2:18 The following day, aboard Zephyr IV at Poole Quay Boathaven, he charges the unit from shoreside 240V AC; it reaches full charge in just over an hour at 600W, with the cooling fan nearly silent throughout.2:50 He then runs a series of load tests: an eWincher electric winch handle charger, a 160W orbital sander, a 2 kW heat gun on both settings (drawing 190W on high, above the unit's 1,800W rated output), and a 1,800W induction hob that boils water while drawing just over 1 kW and leaving 82% battery remaining.5:41 A Henry vacuum cleaner on boost pulls 1,151W without issue.8:55 Finally, Dave connects the BLUETTI to the boat's shore-power inlet via an adapter, running the ultrasonic antifouling system, a 416W battery charger feeding four 125Ah lead-acid batteries, and a small immersion heater drawing just under 1 kW — all simultaneously.10:39 The unit handles every load without audible inverter noise.12:13
