5.0 out of 5 stars Bestek power supply
Bought it for Kooltron P-65 12v cooler. Read where many comments were made about the problem of the plug-in would heat up and melt, when used for extended use. This unit is a very heavy duty appearing item. It has not gotten more than warm with using it for hours. I would recommend it to anyone who needs a well-made item for 12v use.

2.0 out of 5 stars Disappointed in output
I chose this adapter for its 7A / 84W rating to handle higher loads. With no load or light load (GPS or cell phone charger) it outputs 12.3V. While this is technically "12V" and will work for most small devices, that voltage is not the same as an automobile cigarette lighter voltage which is usually between 13.2V to 14.4V while the engine is running.

But that...

I chose this adapter for its 7A / 84W rating to handle higher loads. With no load or light load (GPS or cell phone charger) it outputs 12.3V. While this is technically "12V" and will work for most small devices, that voltage is not the same as an automobile cigarette lighter voltage which is usually between 13.2V to 14.4V while the engine is running.

But that is not the biggest problem. I could live with 12.3V if it could hold that voltage output that at higher loads, but at a 2A (5ohm) load the output voltage drops to 10.2V, which is only around 20W, far shy of the rated output of 7A or 84W. I didn't try with higher loads as that is already too low for what I needed.

So if you're looking for 2A or higher output, look for a different product.

I bought a new r/c airplane that only had a dc cigarette lighter plug for the charger so i needed this product to charge the batteries at my house. It works well and i was surprised with how sturdy the thing is. To be honest for the price i was expecting a lot less.

1.0 out of 5 stars Not able to power up my Car 12V, 2A Car Vacuum Cleaner, May 27, 2014

I bought this for using the car vacuum cleaner at home, the Vacuum Cleaner is rated 12V, 2 Amp, and this DC adapter is rated 7A, but this DC adapter is not able to power up the Vacuum Cleaner, it is a waste of money.

I wanted to make a heated car seat pad workable in my office chair. I bought this adapter and it works great! No problems and I have been using it nearly every day.

I bought this adapter to use in conjunction with a 12v automotive tire air pump. I was a little worried the pump may draw too much current, but I was wrong. This adapter works great!

I bought this adapter because of a very competitive price. So far it works just like its more expensive broken "brother" (I dropped it on a concrete floor). To my surprise it is really capable of handling the indicating amperage. I can definitely recommend this adapter to everybody.
