Great for starting riding mower
I bought this item specifically for my riding mower which had been sitting all winter long. Plugged in the charger for a couple of hours and the riding mower started right up. Rating:

Should be called "Plug-in Battery Charger"
I purchased this product thinking it would save me from being stranded on a deserted road with a dead car battery. Not so. Not till I purchased it, unpacked it, and thoroughly scrutinized the manual that I discovered that the charger needed to be plugged in to an outlet to work; in other words, it's only useful if you're within extension-cord distance from your home. A lot of the reviews on this site for this product are from people using it to charge small recreational vehicles, mowers, etc. If you want to use this product for your car, forget it. It also requires a very specific type of extension cord; in the "preparing to charge" portion of the instructions, users are instructed to "clean the battery terminals" and then "add distilled water to cells until battery acid reaches level specified by battery manufacturer." The manual also suggests removing the battery from the vehicle in order to charge it, in some instances. I didn't intend to become a car mechanic by purchasing and utilizing this charger. Find a portable one; this one's not worth the trouble. Rating:

DOES EXACTLY WHAT IT SHOULD!
I bought this for my riding mower, because the battery is not what it used to be. I hooked the charger up, and yes it's alittle loud but the mower is not near the house so that's not an issue for me. I let it charge over night and it started like a champ. The next time I went to cut the grass...you guessed it it was dead, so I hooked it up for about 20 mins. which gave me just enough juice to turn the engine over.
Great product! Rating:

NOT EXACTLY AS DESCRIBED
I purchased this product on-line because description stated it had multiple ways to connect including a cigarette light plug. The unit I inspected at the local Wal-Mart did not. This unit came exactly like the one at Wal-mart.
Good small battery charger but only has cable clamps. Rating:

Black and Decker Battery Charger
This product works great, and is well worth the price. My only concern is the plastic case, will it hold up over time? |
