Your browser does not support HTML5 video.  I wanted to add a review of this product. I have wanted a jump starter for some time. I looked at the 4000a NOCO and just couldn’t justify the price. So I settled on the Autogen version since it was a little cheaper. I received it for Christmas and shortly after let my diesel truck battery go dead. I was happy I would get to use my new gift. Unfortunately it would not begin to jump my truck off although it had similar specs as the NOCO. I returned it to Amazon and replaced it with the GooLoo version. A few days ago I found my truck battery was dead again due to leaving an accessory on all night. I was happy again that I would get to try the GooLoo. It preformed flawlessly.For reference my truck is a 2008 Dodge with 6.7 diesel and the batteries were way down on charge.I also on a Case 70XT skid steer which has developed a slow drain. The GooLoo has jumped it off multiple times without recharging the GooLoo in between jumps.I highly recommend this product.

After 15 months my Noco GB150 died, out of warranty. I purchased the Gooloo GP4000, with very similar specs with the Noco GB150. I have not needed it to jump a car yet, so I can't attest to how well it works. Both are 4000 amp models.Comparisons:Weight: Gooloo 2.6# vs Noco 6#Size: Gooloo 9 x 3 3/4 x 1 1/2" vs Noco 11 1/2 x 5 x 2 3/4"Ports: Gooloo USB and USB-C vs Noco USB and 12V round plugCase: Gooloo case vs Noco bagGooloo is half the size, weight, and cost. The manufacturer's specs are nearly the same.Noco has a nice voltmeter.Since my Noco gave out too soon, I opted for the Gooloo.Addendum: Second picture added shows the small lights and "Boost" button next to the status lights on the side of the "Smart Cable Plug". Read page 5 of the manual for operation. The "Boost" button is pushed if the green light is blinking with buzzing, waiting for the green light to be steady.

Started my E350 motorhome that had a dead battery after sitting for 10 months. When I say started, I mean turned it right over with no hesitation. And it was too dead to even scream at me for having the door open when I turned the key.It has started my kia soul half a dozen times before I charged it.It did not quite work on my E350 powerstroke diesel with a 7.3, but that battery was bad and so dead my slow charger wouldn't even try, just kept saying I had it hooked up wrong. Ended up having to hook up an explorer for close to an hour before it would turn over.Replaced the battery on it and will update if it works the next time I need it on the powerstroke.Oh, and it weighs nothing! It's so crazy. My brother laughed at me when I got it out to start the RV. He was shocked!

I purchased the 4000AMP Gooloo jump starter when my stored vehicle’s battery suddenly would not hold a charge. When all was said and done I ended up jumping the V8 powered Vette roughly 5 times before I could locate and replace the battery. I also jumped a 24HP lawn tractor once too. This was all within the 1st week of receiving the unit with one initial charge.All said I did not put a meter on this and test it for its rated power. But for its rated current it is compact & lightweight, seems well built and performed as advertised (so far).It seems this little unit can take the place of an old style 80lb battery charger/booster with wheels. I just put mine in storage

Thankfully I've only needed it once but it did exactly what it's supposed to. Diesel Caterpillar 3126 and it didn't struggle a bit!

Based on a review I read on Wirecutter, I purchased two Weego 66.2 jump starters as xmas presents for family members. Both Weegos failed to start a 4.7 liter gas vehicle parked in my driveway. The seller of the Weegos, ESB Warehouse, tried to play games and deny a valid return. Fortunately, Amazon stepped in a quickly resolved the matter in my favor.Anyway, I saw some real world testing of competing products on the 'Project Farm' YouTube channel. The Gooloo did well. I tried it on this same vehicle and conditions that both Weegos failed on, and it started right up.The Gooloo is made in China; so, we'll see how long it lasts, and who knows whose intellectual property they've stolen along the way. If it fails, I'll try the more expensive Antigravity Batteries XP-10-HD.I am giving the Gooloo 4 stars because it works well, but its clamps, case, and waterproofing are inferior to the Weego. I took a star off for that.

I had a problem with the cable assembly on this. I contacted customer service and they got back to me quickly. A couple days later I had a new complete unit in the mailbox!!! I can't believe the power this thing has! I used it 6 times on a V-8 vehicle and still has 1/2 charge left. This thing will slide into your back pocket too.

We use this product constantly in our line of work (boating) when we go on service calls.
