Review: Compact and light for a 500W inverter. High efficiency - Great little unit. Works brilliantly powering the 'sensitive' items I've tried so far, all using the 12v power plug. Fan runs immediately from switch on and is noticeable, as others have commented. Case remained cold at the loads I was running. The supplied croc lead cable is not of sufficient size for much above 300W, and would need upgrading, but that's not an issue for me, and I would recommend this unit and buy again, especially at the price, and fast delivery.
Review: Great - Easy to install and works perfectly as expected charges all 12 of my tool batteries on the move could not ask for better

## Features

- 【A Real Powerful Inverter】BESTEK inverter is an inverter product that can convert 12V DC into 230V AC stable output and can be used in a variety of scenarios. If you drive outdoors, you only need to connect the power it can bring unlimited energy for your electronic equipment.
- 【Multifunction】The inverter is equipped with two binding posts, two 0~2.4A USB ports and a UK standard that can output 230V alternating current. The cigarette lighter or alligator clip connected to the binding post can be powered by a 12V car cigarette lighter or battery. The line loss compensation function is specially designed on the 2 USB ports, which greatly improves the charging efficiency of electronic devices.
- 【Multi-Protection】In order to protect the safety of customers, two 40A fuses have been added to design protection functions to protect the safety of products and electrical appliances.

## Questions & Answers

**Q: will this run a xbox?**
A: The xbox will use less than 200 watts so my guess is yes.

**Q: Can you use a standard hair dryer and hair straighners with this.**
A: It is a 500w inverter so it will run most things up to about 400w

**Q: Will this charge up off a leisure battery with a 200 watt solar panel a 42v 4amp bike battery**
A: There is no reason for it not to

**Q: What specification cigarette socket does the 500W pure sine inverter need? Fuse size, cable thickness?**
A: The cigarette lighter plug supplied with the unit has a label attached cautioning the user that the load should not exceed 150W.  If we assume that is 150W continuous with an allowance for a (small!) startup surge as any inductive loads energise, you're looking at a 20A slow blow fuse on a 12v circuit (you cold go with 15A, but that doesn't allow very much leeway).

Cable thickness is harder to answer.  As a rule of thumb, a current density below 5A/mm2 would demand 4mm2 cables as a bare minimum.  For longer cable runs from your battery to the socket, about 1mm2 per metre of total cable length (that is, 0.5m out and 0.5m back) should keep your voltage drop to somewhere around 3% (of 12V at 20A).   I suggest you check those numbers for yourself, though, because I am *not* a qualified electrician, and there may be environment/installation conditions or regulations which dictate different assumptions.

### ⭐⭐⭐⭐⭐ Great

Easy to install and works perfectly as expected charges all 12 of my tool batteries on the move could not ask for better

### ⭐⭐⭐⭐ Good 500w Inverter for TV
*by T***D on 31 January 2023*

I have recently invested heavily in a solar setup to try and reduce our paid for energy consumption. Most of what i have bought includes purpose made solar generators which can be easily transported around the house. I have 3 fixed 200w solar panels and 1 flexible 200w panel which i move around the house dependant on the sun's location. Recently i had to replace my car battery and had the bright idea of trying to use the old 12v car battery as another form of solar power storage. This required me to purchase some additional equipment such as a MPPT charge controller and an inverter. I had a small 300w car inverter that i purchased years ago and thought i would see if it was powerful enough to power a 65" TV. I connected this to the car battery but it did not work, the TV immediately made a buzzing sound and i unplugged it immediately. I highly suspect this may be due to the fact it is not a pure sine wave inverter. I Therefore decided to invest in a small powered pure sine wave inverter - this Bestek had mixed reviews, with some saying it did not output a true sine wave, others however said it worked great. I decided to order and try it out for myself. . The inverter is bright pink in colour and comes with two crocodile clips connectors. The wires are a very thin gauge so i decided to up them to something more substantial. My TV draws around 60w in eco mode with a start up surge just over. The connections to the inverter are simple and straight forward with screw clamps. Once wired to the battery i switched on the inverter and it sprung to life. There is a built in fan which came on immediately even without any load attached - it is fairly noisy! Plugging in my TV the inverter provided the relevant power. There were no humming noises, nor was the audio or picture distorted, this brings me to believe that this inverter is indeed outputting a true sine wave. TV's and other sensitive equipment tend to not like modified sine waves and you will normally hear a buzzing noise. That did not happen with the Bestek. It all worked and i was chuffed! My only criticism of the bestek is the annoying fan noise, even at very low wattage loads the fan kicks in, after a around a minute the fan speeds up and becomes even louder - bearing in mind this was only pulling around 68 watts peak the fan seemed overbearing. We have this inverter in the bedroom and the noise of the fan is distracting, in a larger room you would not notice it as much perhaps. I have included a video review to let you hear the start up fan, towards the end of the video when a small load is applied you can hear the fan noise increase. Build quality wise, it appears good, aluminium chassis, decent UK 3 pin plug outlet, on/off switch on the front and two low powered USB A ports. Overall i am happy with my purchase - it does the job i wanted - i just wish the fan was 'smart' and varied according to need/heat rather than being always on. I hope that you found my review helpful.
