Electricity Saver Plug, Power Factor Saver Device

30% is the maximum the manufacturer claims. Your own saving depends on your wiring, which appliances run through the same circuit, and your tariff. Write down your meter reading on day one, then compare after one full billing cycle. That gives you your own number, which is the only one worth trusting.

The unit carries CE, FCC and RoHS marks and is rated for continuous use. Plug it straight into a wall socket, not a daisy-chained extension lead, and keep the housing clear of blankets and stacked items so heat can escape. Keep the socket out of reach of young children and pets.

The label on the unit is rated 90V-250V at 50/60Hz. Some listing titles round that to 90V-240V, so the rating is the figure to check. If your mains supply sits inside that range, it will run. Confirm your local voltage before you order.

Choose the EU, UK or US version to match the wall socket you actually use. The plug has to fit your socket directly, so check the version before you order.

It is a one-time purchase with no refills, subscription or app fee. Once it is in the socket, any reduction on future bills is return on the single price you paid, and the meter comparison tells you within one billing cycle whether it is working for your home.
