BESTEK Power Inverter 12V to 240V 300W Car Voltage Converter Transformer with PD20W USB-C Port & QC3.0 18W USB Port & 3-Pin Socket for Laptop, iPad, iPhone, Tablet, Camera

This thing is an absolute lifesaver. I work out and about in my car for the majority of the day, sitting customer meetings and the laptop that work give me is terrible. It barely works at the best of times in the battery life is awful. Many a time I've tried to work from the car and had to go to a coffee shop because my battery was dead.This allows me to plug into the cigarette lighter in the car and I can plug a full size UK 3 pin plug into the device and charge my laptop. I'll be honest, it doesn't really charge the laptop particularly quickly. It does a great job of keeping it live while plugged in, which is essentially what I need, but I haven't actually tested leaving the laptop closed or off and charging as of yet because that's just not something I need to do.This is going to save me a fortune of having to go to expensive coffee shops just to use their power.The device itself is made of metal and does feel relatively high quality. It is quite light though in honesty, so hopefully it doesn't end up getting damaged or break in the long term, but it does seem they taken into account things like thermals because there is a fan built into it as well as an on off switch so you don't have to have it on all the time when plugged in.This isn't something that I use every single day, but there's been a couple of occasions since having it that I've just needed to plug my laptop in, do some work, and then head off to my next meeting, and it's been perfect for that.

This inverter is great for travel, it has a very small footprint is very convenient making it easy to hide away under a seat or in a boot.Simply plug it into any accessory socket of a 12-volt vehicle and you have up to 300 watts of 240 volts AC power, enough for laptops to lights. This inverter also has USB A and USB C charging ports, so phones, laptops and any device requiring USB power can be plugged in.In use this inverter is quite quiet, there is a small cooling fan inside that does make a little noise when demanding maximum wattage but this fan also varies with the temperature of the inverter and performs fairly well keeping the inverted fairly cool in use.The accessory plug on this device also has a fuse in it, so if the inverter fails to power up then this fuse should be the first port of call. There is a short cable from the plug to the inverter, it is short for a reason as a long cable could result in DC volts drop, which will upset the inverter and possibly make it shut down.As with any inverters, these are power-hungry devices and will flatten a 12-volt battery fairly quickly (300 watts = 25 amps at 12 volts), when using this inverter it is worth remembering to have the engine running at the same time, especially in colder months.Looks well made and a very useful tool.

This feels good quality on first impressions and was easy to use, plug it in and switch it on.The heatsink casing and fan will ensure it doesn't get too hot.Functionally this is a good inverter up to 300w, peak 400w for 60s.You can't run fridges or a gaming PC but it will let you run a low power TV or monitor. (check before using!)However there is no carry case included, this could be an issue if you are wanting to chuck it in your car or van as dirt could get inside via the fan opening. Suggest to buy a small hard case for it or keep it in the box.Would have also been nice if they included a few cables but that wasn't expected!Overall would recommend but do check what you want to run with it!

A useful little car battery to mains adaptor that seems solid and nicely made. Works and seems stable. Caution is needed with mains converters in general as they draw large amounts of current from your battery for even modest loads, so ideally only use with the engine running and be sure that what you are using is well under 300W… so nothing with heaters like straighteners or hairdryers.My reason for four stars is that i could hear a high pitch ‘scream’ from the converter when in use… faint, and i do have amazing hearing, but there none the less. I will likely use this on boot sales to check things work, so won’t be an issue in that noisy environment, but as i’m sitting now, at home, with it powering an LED light, it’s off puttingly loud for my hearing.

This 300W power inverter is a compact and lightweight device that can be plugged into a cigarette lighter socket to provide power to a single 13amp plug socket, as well as two USB ports and a type C USB port. It is ideal for camping, travel, and outdoor events where you may need to power small appliances such as a kettle, rice cooker, or laptop.The inverter has a built-in cooling fan to prevent overheating, and it comes with a single on/off switch with override protection. It does not come with a carry case or mounting bracket, so you will need to find a way to secure it if you want to use it in a fixed location.Overall, this is a well-made and reliable power inverter that is good value for money. It is perfect for anyone who needs a portable way to power small appliances on the go.Here are some of the pros and cons of this inverter:Pros:Compact and lightweightEasy to useHas a built-in cooling fanHas USB and type C USB portsGood value for moneyCons:Does not come with a carry case or mounting bracketCan be a bit noisy when in useOverall, this is a great power inverter for camping, travel, and outdoor events. It is well-made, reliable, and easy to use.
