Works as advertised, very happy with the purchase

It has an internal fan which is quiet and appears to run while charging. As expected, the supervisor was automatically switched to. The digital screen is clear. However, as an American, I'm more used to measuring temperatures in Fahrenheit than Celsius. This will be my only criticism. Seems to work very well as described.

Pros
  • Confident
Cons
  • Zero

I will not try to charge some batteries

This charger will indicate that a fully discharged battery is fully charged and will simply shut off. Can't turn it on to charge when it thinks the battery is full. I then tried this on two other fully charged batteries and it indicates they are weak and attempted to charge or repair them. Definitely should have spent more money and gotten a good smart charger.

Pros
  • Great price
Cons
  • Crumpled

Restores batteries. What else can I say?

This charger has already saved me $100 by restoring a battery that wasn't holding a charge well. I have already recommended it to two other friends who also bought it. I would say get it. It costs money. It's not magic. If the battery is fried, it will not come back to life. But if it's jittery and you're starting to get stranded, I think this little guy will surprise you.

Pros
  • Everything is fine!
Cons
  • Quality

Best value for money especially with the "Restore " function and VERY GOOD COMPOSITION

I have bought several of these and prefer them to actually similar models from Harbor Tool, Walmart and other companies before. Also, for a reasonable price, I'm thinking of permanently mounting one of these on each battery in our RV so that when using "shore power" we don't have to worry about the batteries staying charged. The "Recovery" feature is also really good when run every few weeks to lower the sulfate levels on the battery plates which should SIGNIFICANTLY increase battery life.

Pros
  • Delivery was very fast
Cons
  • old

Not bad but not great

This charger doesn't like small AGM batteries like NP7. If you parallel 2 together then it works fine. Large batteries seem fine. The restore function works fine. I have several NP7 racquets that have been sitting for over a year and when 2 are tied together everything is fine. Some were below 12V (11.6) and did not come back to life. It's most likely not the charger. Normal charging and repairing large batteries is normal. I used the repair function on 200Ah 11.5V AGM batteries and everything…

Pros
  • Comfortable to use
Cons
  • Slightly crumpled

Revainrating 3 out of 5

normal charger for SPECIAL charging. Clamps resolved in minutes.

like most items from China. Make something with the CHEAPEST parts you can make to make that dollar. Even if it's just a penny more to make something 200x better, it's just not going to happen. it's just their culture PERIOD! However. back to the charger. I suspect that the charging cables are made of copper-plated aluminum and are not properly measured. They should be 10 AWG 100% copper. Clips were enough for 2 battery charges 12VDC 35Ah AGM on the table. I plan to use it to fill up and repair

Pros
  • Stylish and modern design
Cons
  • Only available in white

Better than big brands

I don't know why Revain buried this battery far in the search. It has the best features and a very reasonable price. I compared it to NOCO GENIUS5, Schumacher, DieHard, Black & Decker, etc. They all overlooked an important IEIK feature: * It's a big charger plus a small charger - car chargers (more than 5 amps) usually can't charge small batteries. and small chargers (less than 2 amps) take too long to charge car/truck batteries. This IEC is 8 amps for large batteries and 1.5 amps (they call it

Pros
  • One year trial
Cons
  • Almost never
