Good power for a 12 volt unit

Good power for a 12 volt unit. Not for professionals, but will work great for the average Joe who gets the drill out a few times a year.

this works well although it is not quite as powerful as my previous. For electric powered it as more than adequate

This 12v power supply is a good quality item.  The power adjustment screw provides a range of 10.5 to 13.6 volts.  Be sure to first switch from the default setting of 220v to 115v.

I got this to charge 12v batteries to run a CPAP machine while camping. I have to use a charge controller, but this thing puts out enough to charge the batteries completely. I haven't had any problems making it all night so far.

I am using this as a 12V UPS for my wifi-router, modem, gigabit switch and a tiny led strip.
Power goes out every once in a while and this saves me a lot.
The output is not regulated, which is why I rated this 4 stars, but otherwise a great item !

Plenty of power to do the job. It could power much a larger set of tines. Only 10 inches wide makes for a longer job.

I bought it to power a 12V TV but the TV needed higher amperage. i should have read the specs before I ordered it. I kept it as I am sure I will have otyer uses.

The unit is compact, has plenty of power and appears to work well.  Have only used it one time, but it performed well.

Plenty of power and much smaller than the 12v drill that it replaced.

Great little power supplies for my 12 Volt needs, At this Price, you can't go wrong & if you need extra units, these are your best bet, as at these prices, it sure  bets shelling out Big Bucks, for one While these are on sale.

I previously had a 600 amp unit, which simply wasn't strong enough to turn the engine over when the battery was dead. This unit has power to do the job.

The 'Velleman PSSMV1USA 3-12Vdc Switching Power Supply' Seems to be of a good quality.  All the voltages check out to be accurate and the connection plugs fit together well.

Light enough and small enought to fit into my remotecontrolled miniature drone. I needed a 5 Volt supply that my 12 Volt Battery does not supply. I needed a have an Amp. That would be 6 watts on 12 Volts with this chopper unit it takes only 3 watts on 12 Volts to deliver 5 Volts at 500 mAmp. Seems to work great.
