BESTEK MRI3013BU-updated 300W Power Inverter DC 12V to AC 230V 240V Transformer Car Charger Lighter Adapter with 3 Pin Plug and Dual USB Ports (Black)

It doesn't work. Couldn't charge a laptop

Bought this to charge up phone/laptop etc in my campervan as 12v charging is very slow. Seems to work well and is fairly solid. Only criticism is that you can't use the three pin socket and the USBs at the same time as they are too close together. Not sure if that's a design fault or deliberate.

Beware! This is not a pure sine wave inverter as advertised in the product details. The leaflet that accompanies this 300W Bestek inverter states that it is a modified sine wave. As such, it would not work with my small (68W) Panasonic TV. Item returned and a different brand ordered which also claims to be a pure sine wave inverter 🤞. Make sure anything you order has FREE RETURNS.

I found this product to be a life saver on an impromptu camping trip. It charged my phone reasonably fast although not as fast as I'd expected. Also although there are 2 usb ports in addition to a plug input i could only use 1 usb port whilst my phone charger was plugged in as the plug partially obstructed the 2nd usb port. Phone chargers tend to be more square than other 240v plugs and yes I could've charged my phone just using a usb input but that would've been a lot slower. All in all I'm glad i made the purchase. If i wasn't driving around so much though I'd have gone with a power bank rather than a power inverter.

Great item. I bought this as I had an air bed that needed to be inflated via plugging in, I was able to use my car socket to do it when camping without electric. I can’t believe I’ve not bought one sooner, airbrushes up in no time. It’s also handy to charge things as it has the USB ports. Be careful what you plug in though as it must be below 400 watts! You can check this by checking on the plug in most items! I have also used this to plug my crimpers in at a festival!
