GOOLOO GP4000 4000A Peak Car Jump Starter, 12V Portable Battery Booster for All Gas & 10.0L Diesel Engines, USB-C Fast Charge Power Bank, SuperSafe Protection, Emergency Starter Pack

This is awesome. I can charge my old iPhone, my new iPhone, and charge my laptop all at the same time while using them.. and the jumper battery clamps are big and heavy gauge metal. It really gets the job done.. the battery works really good in boost mode when jumping a car battery. I'm very impressed and it's great value for the money..

For its size it packs a punch in comparison to other jumpers with in it's class and at a decent price.. I have two other brands one is a well known brand, they work but if it's cold out or the vehicle battery is really low they struggle, the Gooloo doesn't, it gets the job done.. I even get a second one for my other vehicle no regrets..

I used it for the first time the other day and it worked great. It started my 2011 Ford F-350 6.7L diesel without hesitation. I would recommend getting one.

Best portable jump pack on the market, would recommend. Walmart has the cheapest price on them too for the everyday consumer, so that’s why I bought here.

wow, this was better than expected. I am recently widowed and wanted to have this so i would not have to ask strangers for help, or be afraid of being stranded alone. This thing is idiot proof, so was not at all nervous about hooking it up and a car with hatch left ajar for 2 wks started right up. 🤌I think its a must have for piece of mind. Getting my daughter one!

I have not had an opportunity to use it yet. however it is in a hard plastic container. I really like that. already saved the device when caught in hard rain. dimple to understand , set up añd use. I really like that. overall I am expecting to get many years use.

The 4000 amp battery charger arrived as scheduled. The item was well packaged but when I unzipped the battery charger case the battery charger is damaged. From the cigarette lighter adapter that was on top of it from the opposite side where the cables are stored. Apparently the cigarette lighter charger adapter was inappropriately tucked on top of a cable wire that severely scratched up the surface face of the battery charger itself. I contacted Walmart.com about it and they were happy to refund my money or take off half the price for the item. Note: Test the item and any items to make sure they work before you accept the latter. The item works. It arrived two bars charged and takes approx 3 additional hrs to fully charge. Charging with a phone charger will get very warm to hot. Make sure you charge with a 5 volt phone charger.

I recently placed an order for two jump packs but received two pillows and a football instead. Despite my efforts to resolve the issue, I have been unable to obtain a refund or the correct package from Walmart. Initially, I contacted Walmart customer service and was advised to return the items to the store. However, upon presenting the order number and the sticker on the received items, which clearly indicated jump packs, the customer service representative denied assistance. Subsequently, I engaged in three separate customer service calls, each encountering a different response. One call instructed me to return the incorrect items via FedEx using a return label provided. Another call informed me that Walmart would not accept the return due to the mismatch with the order. The third call, however, suggested that I retain the pillows in the football and that Walmart would issue a refund within 48 hours. Despite these instructions, I have yet to receive a refund or any form of communication from Walmart.

We bought 4 of the GooLoo GP4000's for Christmas gifts , one of which was for myself and the others for our relatives. We had a very cold spell here in Nebraska recently and i found my car would not start. When i took my new GooLoo out of its case, the insulation on both the red and black jumper wires was cracked and exposing the copper wire undeneath. The insulation looks very thin. So, now i have a useless brand new Jumpstarter and have given 3 of my family a potentially dangerours gifts. i hope you can help me with this dangerous and embarrassing situation.
