Worked well, easy to use

VERY PLEASED!!! Works great and exactly what I needed and had more options than what the listing showed. I couldn’t be more pleased.

The only reason I gave this product a 4 is because the first one failed to operate at all. The replacement uint works great so far.

If you have space to store this, like say a shed, or a garage - this is a perfect tool to have on hand. You're probably gonna need it someday, and it works as it's supposed to! It charged up my Cadillac's dead battery which I ccompletely ran down reprogramming the anti theft system. This is not one of the cheaper portable ones even though the price is quite reasonable, it's almost like the ones they use in professional garages but it's not really that heavy duty. I highly recommend this for the hobbyist, the enthusiast, or just someone wants to have the ability to charge up a dead battery. It's a lot better than the smaller ones that are sold commonly.

We had an oops wherein the outlet that keeps the trickle charger on our RV running was accidentally turned off. Our RV has two batteries for the engine, and four for the "house" portion. All six batteries ended up with zero charge on them. Using this, I was able to get the engine batteries up enough to start the engine (after about 2 hours of charging, then a boost), as well as getting a charge on the house batteries to be able to charge them normally with the onboard inverter in the RV. Being on wheels was just a bonus with this unit. Worked great for me.

Bought this is January 24. Went to use it this January, rolled it to the vehicle and plugged it in. Needed to move it a little closer to connect cables, and sparks shot out the vents as a short took place. This case is very hard to remove, to get access to the inside. What I saw was a hot wire terminal had fallen off the connection point and fallen against the case, which created the grounding. I was able to reconnect the wire- but the unit is dead, so the short damaged something in the circuitry.That means the repair may be more expensive than replacing the unit. It's just days out of warranty, past return limits.This was a replacement for a previous Schumaker charger that had worked for over 30 years, that had a timer switch quit working. I gave that to a friend who replaced the timer- and it still works.Companies often decide to cuts costs to keep prices low and profits coming. The terminals involved here were surprisingly poor, not typical at all- and I think the unit failure is due to nothing more than going cheap to save pennies, at the cost of quality and reliability .... And, of reputation. A good brand is worth a lot, provided it represents quality products. In my view, it no longer does.NEW INFO- and sadly worse, which is why my original 3-star rating is now a 1-star.Given I had no warranty, I looked into the costs of service- which are about the same as the cost of the machine. So, I decided to open it up and see if I could do my own repair. As I have been in the manufacturing business for many years, designed and built dozens of products, I'm not an average DIY guy.So...First step, open the case- and that immediately made matters worse. Not only is it difficult; there are parts that are held in place by friction alone; no fasteners. The ammeter and lens is one of them, they just push into a hole. The cord to the ammeter is not connected except by passing through a loop, which is fine except the cord isn't supported either, so the meter and lens immediately fell out, but access to replace them is poor.Overall, I found the inner construction to be as cheap as possible. Every corner cut. While it may work fine out of the box, the idea that it will last for years is no longer realistic. The quality it takes to ensure that durability is just not there.I hate to see a brand name that has meant quality for decades prostituted for profit, by gutting the quality out of the product and riding the brand loyalty- and I think that is what has happened here. Schumacher dominates the market for these things, but now, they are actually China-made. What's more, they now make chargers for other brand names, simply by making minor changes in the cosmetics of the case, so that if you buy a similar competing product- most likely you are still buying theirs, and getting the same compromised designs, materials and workmanship. The saddest part is that with a few exceptions, the cost of building in durability is not that much, they sold their good name very cheap.

Great price like the dial easy to use.
