4000A Jump Starter with 20000mAh Power Bank, Portable Car Battery Booster Pack, Type-C Quick Charge, 12V Lithium Jumper for up to 8L Gas/7L Diesel Engines, EP-166

I watched a review video by Project Farm on YouTube comparing several small battery booster devices like this one. This specific on received the reviewers praise for its features and capabilities. I purchased two, one for each of my personal vehicles. I lent one to my father-in-law to use, he didn’t end up using it, but had it for some period of time that I decided to buy another one. I got my original one back and tossed one of them in my work truck. Up to this point I had never even used this device. During Nov/Dec 2022, we were sent up to work in Connecticut. We picked up a Ram 5500 with the 6.7L Cummins diesel from the warehouse to use for CRAN troubleshooting. We went to start it and heard a click, engine did not turn over. I pulled out the Audew Epower 172 booster, connected it to the battery, pushed the booster button, gave it a couple of seconds, then turned the key. The engine fired right up! Since that morning I have had to use this battery booster over a half dozen times to start that same truck over two weeks of using it. Both batteries are shot from being discharged too far too many times. Now, you can boost battery and run glow plugs once, and boost it again to start it, or bypass glow plug and start it right away. Modern diesels start far better in the cold than they used to 15+ years ago. This battery booster is far easier to use than jumper cables, and you don’t need anyone else to lend their car to jump your battery. I don’t know what this device will do for a completely dead battery, but it will get you going as long as your battery is not completely dead. If your battery is completely dead, it may or may not get you going. I would strongly recommend getting one of these for a personal vehicle and checking its charge level at least every other month and once a month during the winter. I put mine in places in my vehicle where is is not exposed to direct sunlight.

This little tool WORKS!!!!!

Used many times on multiple vehicles, holds charge extremely well for multiple jumps. Keep it in your car for yourself and to help someone else who is stranded. Well worth the money. High quality, comes will all you need for jump starts, phone charging while camping, flashlight, and a high qalitybprotective case. Sleek and small and packs a punch, starts on first turn of the key everytime!

I've had one of these jumpstarters for a few years, so when this one went on a deal i had to grab another one to keep in the wifes vehicle, i wish they had the blue back when i got mine bc it is really nice looking, this thing works great and I've used mine countless times on mowers, quads, my vehichles that sit a while and get weak batteries, but honestly I've used them to help others more than I've used it for myself, i can't tell you the number of times ive helped people in parking lots with those small cheap jumper cables that just don't have enough to fire up the dead vehicle, so i grab my little box from under my back seat and go to the rescue, people look at me like I'm crazy when i tell them i can jump em off with this little thing, then when it fires right up they're amazed, I've even jumped off a co workers diesel truck, and several bigger work trucks, this thing is worth every penny, esp when you're in the middle of nowhere alone with a dead battery, not to mention being able to charge devices like phones and such, I've used it several times during power outtages to get our phones charged up, if you're thinking about getting one, just go ahead and do it, you won't regret it.

I have not used it to jump start anything yet. Hower it can hold a charge . I have yet to see charge level low.

It used to be called a different name than what it is currently. It works. Once you hook up the clamps to the battery, press the small black button and start vehicle within 30 seconds. Probably won't help if the vehicle battery is frozen or has lost more than 50% of it's charge. Won't save a total crapped out battery. Carry case is decent. Don't leave it in your vehicle in the winter. Bring it inside and keep it at room temperature. Yes, it can charge your cell phone and other things. It has a flashlight. Durability? Well I wouldn't drop it when it is minus 15 degrees out. The clamp cables are short. To store them in the case, you basically have to tuck one clamp behind the netting and leave the other clamp on the outside of the netting. I have used it to charge my phone, jump start my scooter and to jump start a car.

I decided to order this after having to jump my battery more than once. It arrived the night before I needed another charge. I unboxed it , and followed a brief video. With in seconds I was up and running. All parts are high quantity, easy to use, great hard storage case with a brick. It offers a "C" to "C" connection instead of a micro USB. The unit is multifunctional and all parts work as promised. Keep in mind the company has rebranded to Andeman, so beware of knock offs using Audew in the name. This is a must have in your arsenal. Too many people don't want to stop and help or only will if they are paid. For women this is a safer option. This is a great Xmas gift for the right person. When available... blue, red and black are the options. Red is available in limited supply, and the others are harder to find.

This charger is great unless your battery is completely flat, i have jumped 4 cars with it and it was still over 80% best thing I have ever bought since heavy gauge jumper cables, I would reccomwnd this for any roadside prep kit
