## Description

Product Description BESTEK 300W Pure Sine Wave Power Inverter Modified Sine Waves (MSW) are not smooth, flowing waves. Instead, they present a wave form that has steep crests followed by a sharp plateau and then a steep trough; that is why MSWs are also known as 'Square Waves'. On the other hand, the Pure Sine Wave is a smooth, more constant and flowing wave form. Therefore devices will run smoother, cooler, quieter, and will not be damaged from a MSW's sharp on/off fluctuations. Wide Application Occupying a small iPhone-sized space, easily fits under the seat, in a center console, glovebox, or in your vehicle's trunk. It's ideal for today's compact cars or where space is limited, like on a motorcycle or boat. Pure Sine Wave Inverters provide safe and constant power supply for larger appliances such as: computers, laptops, TV, mini fridge, PSP, etc. 4.8A dual Smart USB ports charges all your mobile devices: iPhone, Tablet, wearable, iPad, camera, GoPro, smartphone, FRS Radio, GPS, etc. Product Specification Power (1 AC Outlet): 300W Rated, 360W Max, 700W Peak Input Voltage: 12V DC, Output voltage: 220V~240V Dual USB Port Output: DC 5V, 4.2A rated, 4.8A Max. Auto 0~2.4A*2 Indicator: Green-operation, Red-shutdown Over Voltage Shutdown: DC 15V-16V, Low Voltage Shutdown: DC 10V-11V Optimal Use and Precautions For DC12V ONLY, not applied for DC 24V and airplane use. Please do not leave the Power inverter in the ON position while your car is off. If the rated input of any connected AC devices exceed 150W, please use battery clamps to directly connect to your vehicle's battery as most vehicles 12V ports are rated and fused for 150W. Caution! Not designed for high power electric devices such as hair dryers, electric heaters, curling irons, etc. Package List 1 x 300W Power Inverter 1 x User Manual BESTEK Advantage UK's leading power inverter brand.

Review: Price and performance - Fantastic power inverter, works great in 12 volt or plugged in, would highly recommend.
Review: Good inverter but noisy fan when used indoors - 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.

## Questions & Answers

**Q: What are the dimensions of the 300W version please?**
A: 8.5" long x 4" wide x 2.5" long. and it does produce a pure  sine wave, I checked it with my oscilloscope. Beware of cheaper inverters that boast a pure sine wave: I first bought one for £25 and it knackered my old transistor radio. When I checked that one, it was producing a modified sine wave i.e a square wave or block formation. With a 65 watt load, the Bestek takes 5.7 amps from the battery.

**Q: Does it have a built in fuse that can be changed if blown? or if i wire it straight to my car battery, do i need to install a 30a inline fuse?**
A: If you connect directly to a battery simply install a 30 amp inline fuse on the power cable and you’ll never blow the internal fuse 👍

**Q: What are the dimensions of this item? Does it come with cables to attach to a battery?**
A: 6.25" x 3.75" x 2"    It comes, as illustrated, with a  plug to go into your car cigarette lighter. I wanted to run this off a battery, so cut off the plug with enough lead on the plug that , by plugging it into a car socket, I could ensure I got the polarity right.. With a 65waat load, the invert draws 5.7 amps, and it is a pure sine wave, it will run a music centre, radio etc without any problem.

**Q: Would this work with my laptop charger, which is 230watts?**
A: Yes it will without a problem.  Be aware that the unit is plastic so uses a fan to keep it cool meaning if you're pulling 230watts(this seems quite high for a laptop and is probably a peak power rather than continuous), you'll have constant fan noise at 230w - it's not massively loud, but it might be distracting.  Maybe just go for a 12v dc-dc adapter instead?   Ours is enclosed under the bed in our camper and it's still audible when delivering just 100watts.  still a great product though

### ⭐⭐⭐⭐⭐ Excellent and to specifications
*by M***W on 9 December 2025*

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.
