Which Should You Buy?
There are two main differences between a pure and modified sine-wave inverter: efficiency and cost. Pure sine wave inverters are good at two things: efficiently powering devices that use AC, and powering devices like radios that can suffer from interference. But, they can be expensive.
-
How to choose a power inverter?
It mainly depends on the total power of the device you want to use with the help of the inverter.
If a 1450W coffee machine is connected, the minimum power of the inverter must be 1500W. It is necessary to consider starting the peak, for example, the power of the refrigerator is 3-5 times higher than its rated power in order to operate. If you have any questions, you can consult us.

More details and tips:
• Sensitive loads like Mac Book please choose Pure Sine Wave version inverter, B07W3B5YGN.
• If the rated power of AC devices exceed 150W, please choose battery clamps version as most cars 12V ports are rated and fused for 150W.
• Please do not leave the power inverter in the ON position while your car is off.
• Disconnect the positive battery terminal before doing any wiring to the inverter.
• Do not put the inverter into sunlight directly, keep it in cool and dry environment.
• Don’t use the inverter with a product that draws a higher wattage the inverter can provide, as this may cause damage to the inverter and product.
Package List:

Inverter Selection:
1. Rated power consumption: One of the following is shown in the instruction manual of the device or the specification sheet of the product body.
○○W: The power consumption.
○○A: The amperage (A) value multiplied by 240V (voltage) is a reference value for power consumption.
○○VA: Only a reference value for power consumption (W).
2. Maximum power consumption: Depends on the connected device. In the case of inductive loads, the maximum power consumption is 3 to 8 times the rated power dissipation, so power dissipation during startup or operation may exceed the rated output connected to the device.
3. Even devices with the same rated power consumption may not be usable because the maximum power consumption varies by manufacturer and construction. Please contact the manufacturer of the device you are using for the maximum power consumption of the device.
4. Make sure that the maximum power consumption of your device does not exceed the rating of this product.

- Reviewed in the United Kingdom on 7 January 2022Size Name: 300W pure sine wave with UK SocketVerified PurchaseWhat a difference!
We were experiencing difficulty with our previous inverter. This was a cheap and cheerful modified sine wave unit that started out well with our old FL bulbs but seemed to be incapable of driving the 1521 100w lumen led replacement lights we had fitted to our stable block at anything much above a medium glow.
Whether this was down to the inverter or the lights is moot, but I decided that a quality pure sine wave inverter that delivers at the 240v as opposed to 220v end of the spectrum would probably be the best way to go as I couldn't face the hassle of having to select lights to suit the old inverter.
Having done my research I settled on this unit and so far it has delivered the goods, pure bright light from all bulbs, which makes mucking out much more viable. Only had the unit a short time so cannot comment on its longevity but it feels solid, well engineered and so far has been performing without fault through the vagaries of british winter weather.

- Reviewed in the United Kingdom on 3 June 2025Size Name: 300W modified sine waveVerified PurchaseUsed this during a recent weekend trip and it powered everything I needed — MacBook, camera battery charger, and a small fan — without any issues. The 230V socket and USB-A ports worked perfectly, and it didn’t overheat or make any strange noise even with continuous use.
Cables are solid, the fuse is built-in, and the size makes it easy to tuck into the glovebox or boot organiser. Only slight downside is it’s a modified sine wave, so not ideal for sensitive electronics — but for most standard gear, it’s absolutely fine.
Ideal backup or travel solution if you’re frequently on the road.
- Reviewed in the United Kingdom on 19 November 2020Size Name: 2000W Inverter with Wired RemoteVerified PurchaseThe difference is like night and day, Depending on your 12v supply this will power anything you throw at it, Of course being limited to 2000w But mines did power a 3kw heater before it cut out after 5 min, I've yet to use it to power my welder with it but the signs seem to point in the right direction for its capability,
Don't buy chinese crap like I did before, If it's too cheap to be true it probibly is, 2000w Modified Sine Wave Inverter under £100 will most likely not be a 2000w inverter, It pays to shop and look around when your looking at reviews like mine.
Make sure your battery is up to the task, Use a 180amp battery with 800cca anything smaller and the battery will die out in no time, But if you can't afford one big battery link 2 or 3 batteries together, I don't mean 24v or 38v link of course link just the positives and negatives to increase your amps, This is how I run my van in this set up using a double alternator set up with two batteries, Never had an issue keeping supply to the inverter,
- Reviewed in the United Kingdom on 1 December 2023Size Name: 300W modified sine waveVerified PurchaseThe equipment I use on a day to day comes to a total of 1.5Amp at most. Most of the time there is power when im installing so no need for the inverter. First time i used it great, no issues nice LED display overall product great. Second time I had to use it in 4 months and it stopped working instantly before I even plugged anything into it. Would not come back on at all. If this was a one off fair enough but used twice in four months and failing on the 2nd time is not a great start.
- Reviewed in the United Kingdom on 4 November 2021Size Name: 300W pure sine wave with UK SocketVerified PurchaseOk I bought this to run a 40 inch Samsung TV and a xbox series s in a camper. It works well. I have mine connected directly to a leisure battery. Tv is rated at about 125watts and the xbox series s is probably around 75 watts when playing games. The fan kicks in on the inverter with both plugged in and in use, but it keeps it cool. Its not the quietest I've heard but reasonable if you're watching a movie or playing games. Ive not tried it plugged into a cigarette lighter socket, as I would say the wires on a car usually aren't thick enough to run this kind of current draw. That's my opinion. I may be wrong. Personally ide run a separate cigarette adapter from the battery to power it. Or i wouldn't be surprised if the inverter shut down when trying to run heavy loads on some cars.

4.0 out of 5 stars GIANDEL 2000W Modifizierter Welle Wechselrichter
Im Großen und Ganzen leistet der Wechselrichter seinen Dienst. Über Solarpanele, 600 Watt kann ich meinen Whirlpool damit betreiben. Nun, die Heizung natürlich nicht. Die verbraucht 2400 Watt. Aber die Wasserpumpe und die Luftpumpe ohne Probleme. Die haben einen durchschnittlichen Verbrauch von ca. 800 Watt. Leise ist der Wechselrichter im Betrieb aber nicht. Wenn ich auch meinen Laptop oder Fernseher daran anschließe, surren die Netzgeräte. Liegt wahrscheinlich daran, weil der Wechselrichter keine reine Sinuswelle hat. Ob das surren gut für die Elektrogeräte sind, kann ich nicht beurteilen.
