What a great price; I have wanted one of these 'pure sine wave inverters' for a while, and jumped at the chance when I saw this one on Amazon. The unit is light and portable, fast charging my laptop and phone, it was easy to plug into the supply in the car, the old cigarette fitting, or similar. It does create a slight humming noise when in use, but nothing too annoying. A green light is visible when it is in use, and thankfully it doesn't interfere with the car's electrics. A decent length of cable so can be placed on, or below the passenger seat. I've used several times now and the unit appears to be safe, and reliable. A great piece of kit, at a decent price; would recommend.

Initially concerned that this wasn't right but it was fine and am well pleased with it runs laptop perfectly, runs my small tv (24inch RCA LCD at 40w) perfectly and no issues. So would be happy to recommend.

Revuew for bestek 300w pure sine wave inverter. So far excellent, plugged in and switched off no draw and switched on with no load 6w. Fan is quiet and it delivers its stayed power without problem or getting hot. Power is clean and tv / radio and pc no problems. This is for devices up to and including 300w continuous.

I bought this to power a small TV in a campervan, which it does with ease. However, the small cooling fan that exhausts air from the end of the unit was making quite a din - easily audible above the TV and quite irritating. To fix this I replaced the original 12V fan with a Noctua NF-A4x20 FLX from Amazon (ASIN B071J8CZP9). The inverter is now so quiet that I initially thought the new fan wasn't working - but on close inspection it was happily spinning away. BTW, I do realise that I've invalidated the warranty - but for the cost I felt it was worth taking a small risk that it might break down in the near future.

I am pleased overall with this inverter. I use it on a home built solar panel/battery power supply. I have removed the screws that hold the fan in place and that has helped to have it running a bit quieter. The fan is still doing its job properly, its just not reverberating in the case as it used to be. when it was hard fixed. I have not run the inverter to its capacity limit, but find that when I plug some mains equipment which normally run at power below 20 watts, the initial surge causes the inverter to trip and the red light shows until I turn the inverter off and back on again. I'm talking about plugging in a laptop charger or a 20 watt TV. So I can't really rely on this inverter to just work on some of the things I wanted to use it on, without having to reset it on the odd initial surges from some devices. The inverter has now been demoted to power garage lights only. It appears to have a standby running current of about half an amp when not supplying mains electricity to equipment.

Fantastic power inverter, works great in 12 volt or plugged in, would highly recommend.

Hi. I bought one of these in October last year. It had been working fine, on the occasional, infrquent times I used it. However, it recently failed. The item came with information that suggested an 18 month warranty. So, I contacted Bestek about the failure. Eventually, after about a week, I received a response - asking me lots of questions about how I used it etc. I responded as soon as I could - and am still waiting for any further communication, 6 days later . . . So, be wary - it may claim to be guaranteed, but Bestek do not seem keen to honour that guarantee. UPDATE EDIT, 23.08.2024 - I did, eventually, hear back from their "customer service". They eventually appeared to accept the fact that their unit had failed,after less than 12 months of very light use. And their resolution? To offer me a 40% discount off my next purchase of one of their products. I declined and advised them that I would look elsewhere. I also informed them that I would NOT be recmoomending their products to anyone else, if I were to be asked . . .

Works perfectly well. BUT mine only lasted 13 months

So far so good

It is what I expected and does the job I need it for.

This allows me to run low wattage, 240V devices from the back of my car. I have hooked up my car fridge (45W) to the Bestek and it runs really well.
