Professional-Grade 7000A Peak Car Battery Jump Starter (All Gas/10L Diesel) 5000A CCA Portable Car Jump Starter Battery Pack, 12V Safe Jump Box Jumper Starter with Extended Jumper Cables, DC, Lights

This charger is powerful enough to jump start most engines yet is compact enough to be easily stored. It was charged to about 75% when received and fully charging took about an hour with a 35W adapter.I have not had a need to jump start anything, but did use a USB port to charge a device and it works as expected.Along with the jump starter, the kit includes a case, jumper cable, USB A to USB C cable, a cigarette lighter adapter (which uses the same connector as the jumper cable) and a manual with instructions in many different languages.The case includes a cloth divider to protect the jump starter when closed. It would be nice to have basic instructions printed on this divider for ease of use.Pros:Battery capacity - should be able to jump a wide range of enginesCompact sizeIncluded caseCons: plugging/unplugging the supplied jumper cable or cigarette ligher adapter takes a lot of effort. The connector requires a lot of force to insert and remove.Both USB-A ports also require more effort than normal, but they do work fine.When the jumper cable is plugged in, the LED flashed alternating red/green. This seems odd to me as I would think its showing an error. Based on the supplied manual, this is normal. Seems odd though. I would expect a solid green when ready and solid red if it needs to charge and flashing red if there is an error.Note: After buying this for over $110, the priced dropped to $70 and has a 50% coupon. For $35, this is a great option that I would recommend.

Short story: this is a great little time saver that works like a charm.For some background, I have a truck that I frequently need to jump-start as the battery sits too long without use. Typically, this requires connecting the jumper cables to another vehicle and letting it sit for a few minutes to charge up before I turn it over. Even after a couple of minutes, it would still crank rather slowly. Growing tired of dragging out the cables, I thought I'd try a portable unit, but I wanted something small enough to fit under the seat. After some research, I purchased this unit from BuTure and I've been very happy with it. After charging the unit, the next time I needed to jump-start that truck I connected the charger, turned the key, and it started right up. No waiting, no slow cranking, it just worked. I've used it two more times since then and the unit still shows 90% charge remaining. It's been such a time-saver (and hassle-saver) that it's gained one of the few 5-star ratings I've ever given.

I've literally charged it one time and I've jumped my car maybe 20 times? I'm still at 71%... I have a Lexus LS430 with a V8 - it's not a small engine and requires quite a few cold cranks... I've had this for about 3 years and have bought 2 more units since. One for my wife and one for a friend, I also told a couple of friends and they all have said the same thing I'm saying here below... no one has had a single issue, and peace of mind for this price is a no-brainer.**Why have I jumped my car 20 times you ask? I'm cheap and lazy: my battery went bad twice in the past 3 years. I ordered a new battery both times for cheap online - all because jumping my car is now so easy that it didn't phase me.Here's the list of why this is the easiest purchase I've made for my car:-I'd easily pay 300+ for this - I can't believe this power bank. If I didn't have it for my car, i'd throw it in a suitcase or for a camping trip. The power is insane.-Jumps my battery that's cranking a V8 instantly. Literally instantly. I've never waited a single second from plugging it in to turning the key: so basically the walk from my front tire to the driver seat.-I timed myself this morning cuz my kid left the door open and the battery was drained. 28 seconds from when I realized my battery was drained to getting the thing out, attaching the terminals, and turning the key. I'd say that all said, it cost me about 1 minute of time to get out of the driveway...I'm a social person, but I sincerely hate asking people for a jump, carrying around cables alone is so ridiculous.-This product fits in my glove box or anywhere, takes up a fraction of the space.-No asking for jumps in a parking lot, calling my spouse, flipping my lid cuz I'm late, or asking a neighbor to wake up and get outside. **Oh and up the meter when it's winter, double the frustration and triple the time.-Gone are the days where I'm using a screwdriver to put my car in neutral, awkwardly getting someone's car lined up and driven onto the curb or whatever. It's insane thinking about times in the past and the lengths I've gone to just get my battery jumped.I will never drive or own a car without one of these in it. Maybe a newer model in the future, but honestly I don't see the need for anything more powerful or with more features. who knows though, maybe it'll sing to me in the next iteration and that could be nice?Anyways, after years of saving my a**, I'm finally writing a review, and it's well-deserving. I don't write reviews unless I'm obsessed or am absolutely pissed off. If you have kids, you just found your next gift for them, they'll thank you at first and they'll worship you once they actually use it. You're welcome.

I am very satisfied with the quality & performance of this jump starter. I've used it a number of times and it has worked well every time. This is so much easier than having to jump between 2 vehicles. I keep it in my vehicle so I'm ready to help others is needed. I liked it so much I decided to buy another one but a different brand that was cheaper. This other one could not start the vehicle. I tried the BUTURE 5000A and the car started right up. I decided to return the other brand & purchased another BUTURE 5000A. Both have never failed and they keep their charge for long periods.

I used this on a car that had sat for 3 years. It cranked it easily. The car wouldn't start but we used this for about an hour while trying different things. It still had 53% left when we gave up. Great price.

The unit is easy to stow in the car and works well

Purchased this for a car starter and for the 12v cigarette adapter. It works well and the attachments are easy to use. I also like the USB plug in for charging phones etc.
