Review: Price and performance - Fantastic power inverter, works great in 12 volt or plugged in, would highly recommend.
Review: AMAZING!! Not ONE issue at all! - Been using this for a few weeks, Plugged a fused power strip into it… So far: Powers a laptop, a home 2.1 Logitech 240v sound system, LED RGB lights, a spare power pack, and recharges my smartwatch + Mobile Phone (via it's built in USB) with NO ISSUES or Overheating. Worth it's weight in GOLD!! No power spikes or overheating… It's been on consistantly and just works as one would hope (beyond it's sales pitch and random reviews). So, from experience = Excellent Product well beyond it's price point!

## 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

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.
