Hakkin Dual USB Port Waterproof 12-24V Car Motorcycle Marine Boat Cigarette Lighter Socket with LED Digital Voltmeter Meter Monitor (Green)

I bought this item to replace the cigarette lighter socket in my car, and to add a USB charging option in its place. I've not been able to leave a 5 star review as it does have its issues whilst doing most of it's job. It charges my phones as claimed, but, even using the faster charging of the two ports, it does it very slowly. I'd describe it as maintain the phones charge, but only very slowly adding to it. Another irritation is that the display flickers almost constantly, so rather than displaying the voltage, it randomly flashes the various parts of the digits rather than the actual voltage figures........but as I said at the beginning, it serves the purpose I bought it for.....just not as well as I would have liked.

fitted this to the dash of my motorhome will charge my phone and run my sat nav at the same time. also shows the standing voltage of the battery when van is parked on drive can see it from outside the van when the voltage drops to about 12.3 volts just put the battery on charge for 24 hrsor go for a drive its the easy way to manage your battery and no more jump starts or new batteries due to deep discharge re charge cycles.

Spot on.I have fitted it up where the sunroof switch would be in my bmw x5.I can run my dash cam without having wires all over.UPDATEIt lasted 2 months then the readout failed just flashing now.

As described. Works nicely. I would have noted 5 but the voltage displaid is not perfectly accurate, as I tried with a professional voltmeter and there is a difference about 0.3 volts on my 12v battery. Still very useful to have

As described, works perfectly. Does drain battery at a rate of about 1 tenth of a volt in 8 hours so don't leave it connected if your bike is stood for weeks on end! Would buy again.

Nice idea but it's too big for a direct replacement of the cigarette lighter socket on my peugeot 5008. I'm not cutting bigger holes in the car. The picture also shows a glossy bezel but it comes in a matt finish.

Worked well for a few weeks then started being unable to charge 2 devices at once, then a week later only one of the USB ports now works. I have another one thats still working fine after months of use.

Excellent I've installed mine on a home made battery bank so I know the voltage to the battery and the USB port for charging my phone and other things free energy brilliant.
