I bought it on 1/26, fully charged it, I needed it on 4/26, the car started immediately and I saw that it was at 40%, after 1 month it went to 0%. It's good to check it every 2 months and charge it, also do not put it in the trunk because if you have an electric car it won't open if the battery is dead.

Very good construction, as well as its case which is like a small suitcase. I charged it once and have used it three times to jump-start a car. The charge dropped from 100% to 80%.

When the battery is below 8.5 volts, it gives you a short circuit indication, meaning the car simply won't start.

Excellent product, it seems very high quality from the first contact. Very important for me is that it includes instructions in Greek (if I'm not mistaken, it is also made in Greece). Also, inside there is a very nice, practical, and good quality carrying case, which can fit all the accessories (cables, etc.). The only thing not included in the package is the charger, but you can very easily do the job with a phone charger, for example.
I used it for the first time on a 1.6-liter car, while stationary, and it started on the first try, without any difficulty.

I got it for starting a tractor three years ago and it is truly a star. However, I knew what I was getting because I had seen the bigger model at a friend's place, which was unbeatable

Excellent technology, amazing power, but... guys, the capacity is a scam! What serious company are you talking about when they add up the amps in series connection... it barely holds 4500. That's it. For amateur use, it's super.

Excellent in every aspect. I have nothing negative to say. Packaging, instructions, operation. At 100% it started an engine 10 times, which had a dead battery that needed replacement and it still remains at 100%. Convenient that it has USB type-C and you can charge it from any charger and charge any device, as long as you have a USB type-C cable

Honest for its money. 2-year warranty for amateurs with the unimac seal. I used it 10 times on 1500 diesel. It never hesitated!! I recommend it.

It works... Both at 30% and 20%. It charged it twice... It fills mobile phones and radios.. Etc.. Time will show for durability..

I got it for a machine. It did its job perfectly. From 54% it charged in about 3 hours. It has instructions in Greek and is quite small. Careful construction with proper accessories.

Only if the battery is dead will it not work. If it is simply drained, then it will start any motorcycle or car engine.

Its disadvantage is that if the car does not start on the first attempt, you have to disconnect the cables from the terminals and reconnect them, and you have to do this every time you try to start the car and it doesn't start. It's a hassle...

Very good product! Reliable. I needed to use it 3 to 4 times and it made me look good.

It does exactly what it should, it's awesome. I started a car with 0% battery power, 2000 cc vehicle.

It starts the engine easily with 2000 cc. It can make 3 starts without recharging. Quality construction and case

I bought it about a month ago and I needed it today.
I used it on a 55 horsepower tractor, model '50, although I had my doubts...
With it fully charged, it started the engine very strongly, it started immediately,
Then I checked and it was only at 90%, it only needed 10%, it really is worth its money

I had been eyeing such a tool for a while until I needed it for a Hyundai accent. I went and bought it, took it out of the box, and immediately used it while it had 30% battery. It worked right away without difficulty... Definitely a very useful tool to have with you. It comes with all the cables and a small bag, except for the USB charging cable, which either it didn't have or they didn't include in the package.

Very good. The 2000 BMW car started right away. The battery was completely dead, not even the lights turned on. Perfect!!!

I needed it twice to start a 2.5cc diesel agricultural vehicle that had been idle for 5 months with a completely dead battery, not even the lights on the dashboard were turning on, and it started right away without a second attempt. I highly recommend it, excellent product with a very good carrying case and sturdy construction.

I used it on a dead battery for my Beverly 250 and since then I haven't had a single issue. I also used it on a 1,800cc car without any difficulty. So far, I am satisfied.

I bought it last week and immediately used it on a Hummer H3, with a battery that needed cables to start. We tried with a smaller starter but in vain. As soon as we installed the Imperia 13800mAH, it started immediately with minimal battery drop of the starter. We will review again after various tests.
