I do not cease to rejoice at the purchase, a very good deal!

Nissan Pathfinder 2.5 turbodiesel starts with a bang! The battery in the car is old, still native from 2022, and this winter it began to fail quite often. And Berkut rescued already 4 times! I definitely recommend this launcher for purchase!

Pros
  • Powerful, good built-in battery. High-quality materials (case, wires), it is pleasant to use.
Cons
  • I would like a little longer wires, for ease of connection

The right product for me, the price suited me.

How to test the charging of the compressor and refrigerator I will write. I immediately see the risks in the refrigerator, with 18W berkut will not pull a 40W refrigerator. But on the Samsung everything was super a few hours of work for the refrigerator was enough.

Pros
  • The very fact of having such a device will not be superfluous for starting a car, but not all of the equipment will be able to be charged, there are restrictions on supporting device charging standards. Well, in extreme cases, you will have a flashlight with a battery capacity of 21A * h.
Cons
  • 1. Larger size and more weight compared to a power bank of approximately the same capacity of 20,000 mAh from Samsung. Samsung in an aluminum case - 396 grams, against 828 grams of Berkuta in a plastic case. 2. High internal self-discharge of the device, even at an ambient temperature of 22C. Most likely self-discharge at low temperatures will be higher. 3. Restrictions on output power and voltage for charging devices via USB and lack of QC and PD 2 and 3 charging standards. Charging a laptop (Lenovo), and now they use a USB-C connector with Berkut, will not work. It was also not possible to charge the laptop through a regular USB, although the maximum voltage output to USB is 12V and 1.5A (this is 18W), and on USB-C (5V and 3A, this is 15W), which should be enough for a "long" laptop charging , and for a "fast" charging of a laptop, 19-20V and 3.25A (60-65W) will be required, but it can be charged with USB voltage at 12V and 1.5A (18W) or 9V and 2A (18W) or at 5V and 3, 6A (but these are the same 18W). As a result, you either have to be smart using a USB trigger, which is another +150 with aliexpress, or carry another power bank with you to charge devices with a QC charging standard and PD 2 and 3.

Tired of the situation when the battery is discharged. Looks like there is a power leak in the car. If it costs more than a week, as a rule, it will not start. A similar incident happened today as well. The car stood for four days, two days -21 and, accordingly, did not start in the morning. I tried to start the car alarm, but it didn’t work, the battery was dead. The car has good wires for lighting, the central lock did not work. The keyhole is frozen. I got tired of these situations and…

Pros
  • Quality, reliability, power
Cons
  • No

Best I have ever used, great product for anyone!

Pros below: It does its job wonderfully, it is convenient that you no longer need to stop anyone and ask for a light. Has some cons: Of the minuses, one can only note that it will not work in cold weather

Exactly as promised by the manufacturer, high quality.

The device looks reliable. So far, there have been no complaints. It coped with the main task, namely, it helped to start a car with a dead battery after being idle in the cold. Has pros: Looks solid and reliable. 2 liter turbo diesel immediately started. The instruction is in 2022, everything is clearly painted. Cons: Short wires with alligator clips for terminals. It would not hurt to add at least 2-3 cm. I barely caught on the battery directly.

Valuable purchase, nothing but pluses!

Has pros: -Large capacity - Large starting current - all cables included Got cons: The disadvantage is more likely not to a specific model, but to the system as a whole. In winter, it is better not to leave

Not a bad product, quite normal quality.

Today I conducted the first test of the Berkut 25000, accepted an order for lighting a Maybach 6 liters V12, the Berkut did the best I can, before that this Maybach unsuccessfully tried to light it from the Volvo S70, they connected the pre-start Vympel 30 to the akum current 20A. Berkut sat down to 75% after 3x attempts, and when connected, it showed a green indicator. 2 attempts with boost did not give anything. The funny thing is that he messed himself up against the background of the Atom…

Pros
  • Workmanship, a set of which many do not have an 18W charger, 2 type C type C and usb A type C cables, an adapter for a power output.
Cons
  • Overestimated displacement by the manufacturer

Does its job perfectly. I don't drive much, the miles are short. The battery does not have time to recharge (SsangYong Kyron diesel 2022 onwards). Previously, after a regular downtime for a week and a half in the winter, he could not start. The battery is relatively old. With this device, the battery turned the starter well, the car started up from 1 time in cold weather. Immediately connected it to the battery, did not tempt fate. And the device is not very discharged. But as indicated in the…

Pros
  • Convenient device. Everything is intuitive.
Cons
  • Despite the instructions, the boost button is active when connected to the battery, you do not need to press it.

Great value for money, one of the best offers.

I have a Land Rover Freelander 2 2.2 turbo diesel. The frost was - 20 degrees (later, as it turned out, the diesel fuel froze in the filter), so I didn’t start the car. But I used the device at 100%, until it was completely discharged. In fact: 1. Spins VERY "fun" / fast. 2. Turned my motor six times, then sat down. 3. After he sat down, I connected him to the USB in the car and he began to charge (from a tired battery !) and added 2 (two) sticks (four in total) and began to twist more, cool)…

Pros
  • 1. Can start diesel engines. 2. Compact. 3. The most powerful on the market.
Cons
  • Didn't find it.

I'm amazed! It was definitely worth the money!

Super helper! When the courier brought it, he did not believe it, he thought he was mistaken, the Starter-charger cannot be so small. But technology does not stand still. I have already used it several times, thanks to the frosts this year (it's -33 C outside now). The car starts with half a turn, the starter turns like a fan! Buy it, you won't regret it.

Pros
  • Small size, huge power! You can charge a bunch of gadgets with it.
Cons
  • No.

Reliable purchase, guaranteed to be a good purchase.

I bought it before frosts, knowing that my battery will not withstand minus 18, since it is no longer new, but it will still be enough for the summer. And now it's 5 o'clock in the morning on Hong Kong street and my honda pilot refused to start making a sound like y, y, y :) The dashboard did not burn at all. By connecting this device, a miracle happened, the lights on the instrument panel lit up and the first time the car started up very cheerfully, as if I connected 5 batteries to it at once…

Pros
  • That everything is well-made and works properly.
Cons
  • No

In use for about a month. Does its job perfectly! I started the car with half a poke at -30 already five times, with a dead battery, the charge level is still 100%. The booster itself is made with high quality: the case is very strong, does not play, does not crack, all connectors are closed with plugs, there is a flashlight, crocodiles are generally fire, charging for 2 USB and Type-C gadgets, a powerful socket with a 15V output. This ROM is manufactured by Carku! An indispensable thing for a…

Pros
  • Powerful ROM, quality crocodiles, case!
Cons
  • No!
