YuanKanJu Sudopo Portable Car Jump Starter 1000A Battery Booster, VIDOKA 12V Jump Starter (Gas Engines up to 7.0L, Diesel up to 5.5L) with Smart Clamp Cables, USB Quick Charge, LED Flashlight

I tried to jump start my car with my sister's car and had no luck. I hooked up this jump starter and started it right up. It only is able to jump start about 3-4 times before I have to charge it. I highly recommend purchasing this device. Very handy!

if you're on the fence about buying, pull the trigger. It's a fine quality product, solid build, and clearly well-thought-out. Far beyond the what you'd expect for the price.I purchased the Vidoka jumper because my 25-year-old traditional trickle charger stopped working; I also wanted a jumper that my wife could carry in her car as well -- something portable and easy-to-use. Just in case.Well, we recently experienced a 3-day cold spell here in the northeast US. Overnight lows bottomed out at -10°F without windchill factor. Our family stayed inside by the fire all weekend. We didn't even start my wife's car once. Frigid temps plus zero driving resulted in a dead battery on Monday morning. Engine wouldn't even turn over.About three weeks earlier I'd received my Vidoka jumper. It was juiced up and ready for it's first test. With clamps connected, the Vidoka indicator lights shined "Green". Engine sprang to life on first crank.Aside from being relieved, I was truly surprised by the Vidoka's power considering how small it is. Fits right in the glovebox and very light.That Vidoka stay in my wife's car now. She commutes to work every day, and often stays much later than most of her colleagues. This jumper provides a nice sense of security for me (and for her), especially as we've only hit winter's mid-point.So far (and thankfully), we haven't needed to jump start her car again. But it's there just in case. Because of the excellent price point, I'm ordering a second one for my SUV.

I knew my truck battery was getting weak, so I bought one of these Jump Packs 6 months ago. Charged it up and threw it in a compartment in my truck. After 6 months without charging the Jump Pack it started my truck! I have a 6cyl engine. I then charged it back up to full and used it to jump my truck an additional 4 times. The Jump Pack still showed full! I have since replaced my dead truck battery but will buy one of these for all my vehicles. I would recommend this to anyone. [Just read and follow the instructions.] Wait for the light to turn green and start your vehicle.

Okay this is one of my best purchases I ever made! I drive a 15 Honda Accord and I am not kidding almost right when I got them it was freezing and my car was dead I thought Omg I don’t have to go wake my neighbor or wait for a jump. I literally clicked on the cables into the unit and put them on the battery light turns green right away I got back in and push my start button and she fired right up! I have jumped others too and same! So so easy and powerful and it’s so little! What a convenient thing to have! Everyone should have one of these in their car! Not to mention my cell phone is like charged super duper fast because it has USB ports. Also has a very bright light in case it’s dark and you need to see! Love it

I love all of the features on this compact strong charger. It fits in the glove box so no one see's it from the outside and attempts to steal it, it has the power of the larger products and just get's the job done on all levels.

Son charged truck today,started first crank!

She was a hot redhead in a jeep. She came into the store desperately needing a jump. I used the opportunity to see if this product worked. Hooked it up to her dead battery turned it on and her jeep cranked right up. No moving cars around, no drama.Buy one and put it in every vehicle you own. Charge it periodically and you won’t need a hero, but you’ll be ready to be one if needed.

After several "dead battery" occurrences with my truck, and getting tired of having to call someone to give me a jump, my son mentioned a portable battery jumper and sent me a link to order your product. It arrived the next day via Amazon Prime. The packaging was very high-quality considering the type of product it is, which made the unboxing a very pleasant experience. I fully charged the unit then repackaged it in its box to store it in my truck for the next-time I have a dead battery. This ingenious little device will certainly give me peace of mind knowing that I can handle any future dead battery issue on my own without inconveniencing a friend, or asking a stranger, or having to pay (and wait) for a jump from a roadside service or towing company.
