Its compact, lightweight design fits easily in vehicles, while built-in multi-protection systems ensure safe, reliable operation during travel or emergencies. ## 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.

Review: A great piece of kit, at a decent price; would recommend. - 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 desertcart. 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. Review: good solid item - 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. ## Features - A Real Powerful Inverter: BESTEK inverter provides 300 watts continuous DC to AC power and with 2 USB charging ports.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ A great piece of kit, at a decent price; would recommend. *by R***Q on 10 April 2026* 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.
