Stanley Simple Start Battery Booster

• 12V vehicle battery booster
• LCD display screen
• Ultra-bright LED light for increased visibility
• Lithium-ion battery technology holds its charge for up to 1 year
• Plugs directly into vehicle's 12V/DC outlet

I charged the unit fully when it arrived. It did become slightly warm to the touch, but it did not get hot at all.

When my 2007 Honda CRV's car battery was sufficiently discharged to a level when it would not start, I followed the instructions on the unit's 12V cable tag. After about 15 minutes being plugged-in and attached to my vehicle's 12V outlet, the unit's display informed me that I could now attempt starting-up the car. I tried it and it started-up successfully!

The next month, my 2001 Volvo V70 station wagon's car battery was now sufficiently discharged that it would not start the engine. This time the unit took the maximum 30 minutes to boost the Volvo's battery. I guess the Volvo has a larger but older battery as compared to the CRV. But the engine was able to start-up too.

I am no expert on car batteries and boosting, but it seems to me that this unit is not half bad!

My unit didn't work right out of the box. When I called tech support to make sure I was doing everything right, I was greeted by a very rude operator who tried to tell me the unit had been discontinued for a number of years and was out of warranty. When I confronted him with the copyright on the manual being just 1 year old, I was told that I should deal with the retailer. I had higher expectations of Stanley and they will be getting a letter from me. This company they have sold their name to (so has Black & Decker and another big name I forget) is destroying their reputation.

Save your money and your frustration.

Amazing product I bought two, one for each child who both work into the early morning hours at their jobs. My son used it immediately, before he had even charged it as I instructed. The battery booster charged his battery and he was on his way in less than 10 minutes.

This is my new favorite gift and I will be buying this for years to come!

It looks like a solid unit, with pretty clear instructions. I had difficulty trying to "revive" a battery in a mercedes S500. This unit simply did not detect that a battery was there, either because the battery was dead or because the accessory outlet isn't hot at all times.

Long story short, I just ended up jump-starting the S500 with my 2nd vehicle. Just for fun, I tried charging my 2nd vehicle (a Chevy van) and it did work, but after the charge cycle the unit's battery almost depleted. So, if this thing doesn't work on the first try I'm not sure if you'll get a full shot at a second go.

This would be ultimate last resort. It comes built in with a flash-light, which I feel would come more in handy in an emergency. Like some of the other reviews state, this is more just to "keep your battery topped off" rather than trying to bring it back from the dead. Just my two cents.
