Universally applicable

This was used to replace a discontinued brand name electric lawn mower battery charger. As it has variable voltage charging function I can use it for all my battery charging needs and it is very easy to use. The only thing I would recommend is a longer power cord.

Pros
  • Easy to use
Cons
  • The list is long.

Maybe it works, maybe it doesn't

I could tell you whether it worked or not if the manual explained how it worked, or even how you can tell it does anything. If you have exhibits, everything should be labeled and explained. This charger might be smart, but the instruction manual is definitely not.

Pros
  • Excellent design
Cons
  • Little things

Easy-of-Mind!: Jump Starters, Chargers & Portable Power Supplies

Arrived in nice packaging. The box is compact and lightweight, making it easy to transport. I love that it comes with a charging cable and even connection cables so once charged it's ready to go. I've had battery issues on a 20 degree snow day before. I would never want to get into a predicament again. Now I have this lightness of spirit. I hope I never have to use it.

Pros
  • Confident
Cons
  • Good but not great

Great Charger

Amazing I bought this electric pallet charger from our warehouse. The charger failed and they charged 600.00 for a replacement. As soon as it arrived I went to the warehouse. Connect the B-Qtech charger to the top battery which was connected in series with 4 batteries. With a 24 volt device and a 4 amp charge in the morning all 4 batteries were fully charged. The electric pallet truck ran for 2 full days before it needed to be charged. This charger worked perfectly. Thanks Steve

Great product but the cables are short and flimsy. However, it works.

Great product Works well. I used it to charge 24V MCI 8D bus batteries. It took 1 day to get them up to 4 amps and this charger did the job. I was a little worried about the very light cables and they were short. The clamps are also weak. However, this works, however I need to change the cable length for my application so I can keep the charger connected to my batteries when parked. I like the LCD screen. It is easy to see in sunlight and at night.

Pros
  • Best in class
Cons
  • Requires outlet

Return, charging voltage too high

I tried to use this charger to service a pair of stock batteries in a 24V ex-military vehicle. The initial charging voltage was 30.0V (exactly) measured on my DVM and 29.8V when the device itself turned on. Due to the high voltage, the batteries immediately and noticeably began to gas. This voltage exceeds all recommendations on the Internet for charging lead-acid car batteries. I returned it and replaced it with a much more expensive DelTran 24V charger that will support the same batteries at…

Pros
  • price
Cons
  • empty

Portable easy to use

They shipped it the day I placed my order and I received it the second day, amazing speed of delivery! The box comes with a charger and an instruction manual, which I don't find useful. Most people find it easy without charging them. My car is a 2012 VW CC with a battery that lasts about 4 years so I bought this charger. Just connect the red wire to the positive pole of my battery, the black wire to the negative pole, it will be automatically recognized and start charging. During the charging…
