Spark 1000W Pure Sine Wave Inverter, 2 UK Sockets, LCD Remote

The Spark 1000W Pure Sine Wave Power Inverter, model SP1-12, sits at number 10 in this guide. It takes 12V DC from a car, van or leisure battery and puts out 240V AC at 50Hz through two UK-style sockets and a 2.4A USB port, with a wired LCD remote for switching it on and off. The finding in its listing is unusual for this category: the numbers agree with each other. The title says 1000W continuous and 2000W peak; the Wattage field says 1000 watts; the Output Power field says 1000 watts; Peak Output Power Watts says 2000. That is the opposite of the pattern in the entries above it, where the big number in the title turned out to be the peak figure. The one field that does not behave is Standby Power Shutoff, which should be a consumption figure and instead reads 90% — a percentage, like the ones filling the same field on other inverters in this guide.

At £109.99 it is not the cheapest route to 1000W, and the listing carries 24 ratings at an average of 4.4. Those two numbers are worth reading next to the star breakdown, which totals 100 ratings rather than 24 — 71 of them five-star and 6 of them one-star. The bullets claim real owners comfortably run a 700W microwave, power tools and battery chargers, and one bullet says the box includes battery connection leads, even though the Box Contents field lists only an instruction manual. Every figure on this page comes from the Amazon listing for this product, not from testing of our own.
