BESTEK 300W Power Inverter DC 12V to 230V AC Converter with AC Outlet and 4.8A Dual USB Car Charger

Product Information

dual Smart USB ports charges all your mobile devices: iPhone, Tablet, wearable, iPad, camera, GoPro, smartphone, FRS Radio, GPS, etc. Works well, very quiet, can't confirm it is a pure sine wave it produces, which is better for running computer equipment off, but have bought bestek before and feel happy with the quality.

Provides sine wave output which is more stable and can be applied to the curling iron, hair straightener and the electric toothbrush within 300W designed for your devices. She has a fast charge 65w 240v charger which really charges the laptop up fast from low to fully charged in about an hour where it then gives about eight hours usage. I did read on the reviews that if you plug it into a low power car cig socket it will sense that and limit it's supply to about 100 watts. And if you had a big inverter supplying a smallish load, the inefficiency is greater as there is a minimum amount of overhead - so if you had say a 2000W inverter for arguments sake and you turned it on to provide a low wattage, it would be more wasteful than using a 300W inverter for the same purpose. The sine wave inverter has well placed thermal protection sensors,The aluminum alloy casing with a few ripples,Unique vents and also a built-in FAN which comes ON under NO any loads or when the Inverter becomes Hot Once Powerred.

Output voltage wave form is pure sine wave with very low harmonic distortion and clean power like utility-supplied electricity. But this way will lead to many problems including a complicated control circuit, more power switch tubes used for the superimposed lines, and larger volume and weight of the inverter. I guess I could plug the inverter into this load socket and then power Michelles laptop to see how much it draws.

If you have valuable or precise devices, you may need a pure sine wave inverter because it provides high-quality, high-efficiency and stable sine wave output, and has high-frequency technology.We don’t share your credit card details with third-party sellers, and we don’t sell your information to others. Pure Sine Wave: Different from the modified wave inverter, the sine wave has better compatibility and can be applied to most equipment which is less than 300W.

A Real Powerful Inverter: BESTEK inverter provides 300 watts continuous DC to AC power and with 2 USB charging ports. AC outlets are for laptops, tablets, string lights, and 2 USB ports are for cellphones, iPad, music players.

If someone gets one of these, would be useful to post heat testing results at 300W, as well as test with a 30A fuse. From the perspective of mainstream inverters, car inverters are mainly divided into two types, pure sine wave inverters, and modified sine wave inverters.

BESTEK 300W pure sine wave car inverter:Its output waveform is same as the AC power waveform of mains power grid which delivers a smoothly-varying sine wave for sensitive electronics provided by the electric utility. Never really used invertors before believing them to be an inefficient use of power apart from an old one Don Madge gave me which was useful for charging old phones etc but I bought this one as Mrs D has a new laptop which I couldnt get a 12v adaptor for and also she knackered her electric tooth brush on the old invertor so as this one is pure sinewave it should have been safe for charging laptops, or other sensitive electrical items like tooth brushes, mobile phones etc.
