Description
A 250 W continuous (300 W peak) modified sine wave inverter — the cheap, honest option for resistive loads only. Modified sine wave is a stepped approximation of mains, not a clean sine. For a filament lamp, a soldering iron or a simple charger it is indistinguishable. For anything with a motor, a transformer or sensitive electronics it runs hotter, buzzes, and in some cases will not run at all. We are telling you this on the product page because the returns come from people who were not told.
| Waveform | Modified sine wave |
| Output power | 250 W continuous, 300 W peak. Confirmed with the supplier: the figure in the model name is the peak, and the continuous rating is what the unit will actually hold. Size your load against the 250 W figure; tell us the load and we will confirm in writing before you order. |
| Output voltage | 220 V AC |
| Output frequency | 50 Hz |
| Input voltage | 12 V DC |
| Dimensions | 160 × 97.5 × 55 mm |
| Weight | 600 g |
Key points
- Fine for: incandescent lighting, heating elements, simple battery chargers, power tools with universal motors.
- Not for: compressor fridges, microwaves, induction, CPAP machines, laptops with sensitive supplies, anything with a mains transformer or a variable-speed motor. Specify a pure sine wave model instead.
- 250 W continuous, 300 W peak. Check the appliance’s start-up draw, not its running draw — motors can pull several times their rated current for the first second.
- Low cost per unit, which is the entire point of this model in a range.
We are confirming the full specifications for this model with the manufacturing factory. Ask us and we will send the factory’s data sheet — we would rather do that than publish numbers we have not verified. Request the specifications.
Specification and socket standard
Externally sourced; we are confirming the full data sheet with the factory. Output socket standard is a build option — tell us the destination market (Schuko for most of continental Europe, BS 1363 for the UK, and so on) and we will confirm what the factory can supply before you order. Request the specification.
Best for
Price-led SKUs and simple loads. If the customer’s list includes a fridge or a laptop, sell them the pure sine wave model instead.
