    It works, performs the stated functions. Started a 3.5L V6 engine with a depleted battery.Color: 3500A Jump starter Ships From: United States

    Haven’t checked yet. But the clamps are a bit small, they won’t fit all terminals. I’ll update the review later.Color: 3500A Jump starter Ships From: United States

    The product arrived quite quickly, delivered by a courier to the apartment. At the time of the order, courier delivery was free, cost me 6700₽. I bought it, primarily as a power bank, but it will also come in handy as a jump starter; I was aiming for a two-in-one. I will test it as a jump starter probably next winter. As a power bank, it’s not bad, I can’t say exactly how many devices it will charge, roughly 3.5-4 charges for something like a Samsung A52, it has fast charging and a convenient charge indicator. It looks simple, but solid. The downside is that only a soft case is included in the set. I bought a hard case from Ali that fits perfectly; the zippered case closes easily, but you have to position the charger and the block with the clamps properly inside. There are instructions in Russian, I recommend familiarizing yourself with the tips, for example, about the need for recharging every 3 months without use and so on.Color: 3500A Jump starter Ships From: United States

    The jump starter arrived on time. Good packaging.
    Initially, after testing, I was upset because apart from charging the phone nothing worked. The device was giving out very low voltage. I opened a dispute. Wanted to return it. But then I gave it to specialists. They looked at it, soldered something, and… miracle!!!! Everything started working.. It helps to start the car perfectly. Thanks to the seller.Color: 3500A Jump starter Ships From: United States

    The delivery is very fast, The device’s standard box was packed in regular film, slightly crumpled at the edges, but not critically. Inside the box, everything is intact, the set is as described. There was no additional gift, apparently I didn’t make the first 100. The device arrived charged to 88%. All non-primary functions (charging the device itself, charging other gadgets with the device, flashlight) were tested immediately after unpacking, everything works as it should. A few days later, I had to start a car with a dead battery that had been standing outside for 1.5 weeks (a pickup, diesel, 3.2 L). The temperature outside was -2. The Fubag Drive 600 starter, bought a couple of years ago, once again couldn’t help. I connected this device, after a second delay, the engine started in half a turn (honestly, I didn’t even expect it). How effective the device will be at lower temperatures will be shown over time. The product matches the description. I recommend both the seller and the product.Color: 3500A Jump starter Ships From: United States
