Battery Tender 2000 Amp Power Station and Lithium Jump Starter, 030-2040-WH

My diesel pick batteries were almost completely dead, truck couldn't even turn over. I attached the booster, turned the key to warm the glow plugs %26 it started immediately. I'm extremely impressed. Even with my two gauge jumper cables Ive never had a vehicle start so quickly.

I've always had issues with my car battery getting some corrosion around a post and then losing connectivity to the car. When that happens, a jump start can get me going long enough to get home to my post cleaner and my trickle charger. But having to rely on strangers is sometimes sketchy and not always guaranteed. This thing is awesome — it saved my bacon not once, not twice, but thrice in a day: to home, then up to get more post cleaner foam, then back home. It takes truly 5-10 seconds max to deliver a charge to the car battery. I have not used and probably won't use as a charging pack for phone or anything like that, as my need is specific to my car battery. I won't go without this thing on long trips — because you don't know when you will need it. And you never know when you can be the Good Samaritan to someone else. Lightweight; appreciate the hard clamshell case; durable build, I don't feel like I'm holding a cheaply constructed item; and easy to charge with 5V->3A usb wall charger.

charges slow with provided charger, only USB. i haven't jumped a car. i primarily use it for a 12v power source to operate auxiliary brake on my tow car behind motorhome instead of running down the car battery. Connected for approx 4 to 5 hours and goes down to 75%, then i top it off to 100% for the next day. 7 days so far and no issues.

I have a hybrid that has a bad Auxiliary battery. It needs a jump almost once a week. My other car is in the shop so I ordered this product and selected the 45 minute delivery. I got it in 20 minutes. I opened the box,hooked up the jumper cables and boom my car immediately started! I just found my Christmas presents for my relatives.

Powerful, portable and versatile, this Battery Tender GoPower2K Portable Power Station And Jump Starter features 2000 AMP and 100W AC power. I like how lightweight the power station is, it is made small but mighty, and with a variety of integrated outlets it is capable of providing AC power, jump starting 8.0L gas and 6.5L diesel engines, and can also charge mobile devices with its USB ports. It comes with a wall charger, type C USB charging cable and a female cig adapter cable. With this this jump starter set comes a convenient zipper case, making it easy to keep everything safe, organized and ready to use when needed. An easy to read bright LCD screen display shows the remaining battery charge percentage so you can easily know when the battery power is low and it is time to recharge the power station. My favorite feature this unit offers is the smart alligator clips that are made with a green and amber LED plus a warning buzzer that will help you recognize and prevent wrong connection, overheating, as well as short circuiting. This spark proof jump starter with reverse hookup protection makes it easy to use for everyone and definitely makes this a must have for every vehicle owner. I make sure to keep it in my truck to have it on hand when I need it. Great quality and durable, I highly recommend it!

It was just as I ordered and wanted.

It does exactly what I need it to. The cable could be a bit longer, and the teeth of the clamps could have a stronger grip, but great product overall and a wise addition to any roadside kit.

I bought it when I needed it. It arrived with no charge at all, which was fine. I got my battery jumped by a neighbor. However, looking at the device, there are no light indicators or buttons or anything you might expect to see on a $150 device to indicate the charge progress, on/off, etc. After a week it still hadn't charged…just as reviews said. Returning! Buy Noco! My friend brought his Noco over. It had buttons and indicators and it jump started my car in 30 seconds! It was $99!

The battery is dead on arrival. Wouldn't power on at all. Plugged in the charger and it immediately showed 100%. Removed the charging cable and it instantly shut off.

Car jumpers don't work. Plug it in and connect to car and nothing. I put it on charger just in case says 100%. I tried clicking any button on it and nothing lights up or sends power to car.
