I haven't had to use this unit yet to jump start a car, but it's good peace of mind knowing that I not only have something to give me (or someone else) a boost, but also to pump up my tires, if needed.I have had a chance to use it to put air in my tires, and it does a fine job -- I was actually a little surprised given that it's not very large.I appreciate the fact that the instructions for the unit -- both for jumpstarting and for inflating tires -- are written right on it, so you don't have to worry about finding / losing the manual and not knowing how to use it. I also appreciate the fact that it came with a tip allowing me to inflate my kids' balls, so I can use it not only for my vehicle, but also for their bikes, basketballs, etc.Very nice unit.

This little gadget was just what I was needing as I am on the road in sales. My daughter was visiting and her battery had died, she was parked in a way I could not provide a jump to her battery with jumper cables. I used the Vtoman I had just purchased to get her battery charged; worked like a charm. I purchased two more, one for her and one for our son! Excellent for anyone on the road as it also includes a tire inflator feature!

Haven't gotten to use it much since receiving but have had an awesome experience so far. I purchased this unit mostly for the air compressor portion. A jump box always comes in handy but I wanted a quick and easy way to air up the helper bags on my truck. This item does it extremely fast and the psi reading is within 1psi of actual. I also had it sitting on the core support of a lifted vehicle when it decided to take a leap off. After falling nearly 3 foot onto a stool and another 2 foot before sliding across the concrete floor, it is still in excellent condition with not even a scratch. So far I am very pleased with it. Also comes with a nice storage bag to keep everything organized.

Great product on sale...plus a coupon attached! I got it super cheap and I know 2 other people who each bought themselves one after hearing about the amazing deal I got! Thanks for the sweet deal Amazon!

My friends are still jealous of me having this VTOMAN. I have helped out a number of folks with low/flat tires. I have not used it to jump start a vehicle, but I have talked to others that had high praise. The unit works so well that I do not even mess around taking out my air compressor anymore. It is way easier to connect the VTOMAN to the valve stem, set the unit to the desired air pressure and press the inflate button. The unit automatically shuts off when it hits the set tire pressure. I have purchased a few of these as gifts for friends as well! My only suggestion would be to complete a little research and see when size unit will work best for you. My personal VTOMAN is likely a bit large for my needs (I do not need to be able to jump start a diesel truck). Once you receive it, be sure to charge it up so it is ready when you need it. Battery life seems to be very good. Though, I still recommend checking it regularly, especially prior to long trips.Highly, HIGHLY Recommend !!

This review is for the VTOMAN X7 Jump Starter with Air Compressor, 4250A Portable Car Jumper with 160PSI Digital Tire Inflator,12V Lithium Battery Charger Booster Box with Type-C Quick Charge (10L Gas/10L Diesel) BlackItem arrived as described in the listing, with no missing pieces or noticeable defects.This came with the battery pack, 8 gauge booster cables, an inflator hose, different pieces to attach to the inflator, USB charging cable, and a convenient carrying case for storing everything together in the trunk of my car.I got this because my second car (a VW Jetta) doesn't get driven often, so the battery does sometimes drain to the point the car won't start.To start, this arrived with a 3 bar (out of 4) charge. I immediately plugged it using the USB-A to USB-C cable in to charge it to 100%. My charger tells me the wattage for items plugged in & charging. This took a 5 watt draw, and took about an hour to fully charge. I did hook it up with a USB-C to USB-C cable, and with that connection it had a 17W draw.The battery clamping piece detaches from the charger for easy storage. There is no need to worry about accidentally reversing the polarity on this. It only plugs in one way, and so long as you put red to positive & black to negative, you'll be fine. There is also a "boost" button on the base of the clamps.This has 8 gauge wires for boosting a battery. This is OK for my usage because the car is only a 4 cylinder. In my experience, the bigger the gauge the better for boosting cars, and the larger the engine and/or colder the day the bigger the wires needed.This was able to boost my 4 cylinder car on a day above 0C with a battery which was not fully drained but didn't have enough power to start the car. Not sure how effective it will be at colder temperatures. I also haven't tried it on my minivan with a 3.6L V6 because that is driven much more frequently and has no issues with the battery.The listing says "able to start all 12V vehicles (10L Gas/10L Diesel engines) up to 70 times at once." If I'm interpreting this right, it's saying it can start seventy 10L engines without a charge (I'm assuming that's what "at once" means vs hooking it up to 70 vehicles all at the same time.I don't have a 10L engine to test this on, but do wonder if an 8 gauge wire could actually handle that. I suspect the charger could handle it but the wires are likely a weak point. Given this has a proprietary connection for the boost wires, it's not like you can upgrade the wires on your own; or replace them if you happen to melt them from trying to boost something beyond its capacity.I have used this on my 3.6L V6 minivan, however. One of my tires has a very slow leak. I hooked this up when the tire was at 24 PSI and it took about 3 minutes to fill it to 36 PSI. This makes is slower than my regular 18V inflator but it's good if you're stranded on the side of the road.The emergency light has 3 modes; white, flashing red and SOS flashing red. This is nice to have if you're stranded on a dark road during a breakdown.Overall, this does what it's advertised to do for my purposes. As I said, because of the gauge of the wires I'm not convinced this would do the job for a V8 or more, but it works for my purposes on my 4 cylinder engine. I'm giving it 4 stars because I think the weak point here is the gauge of the wire.

Très bon produit

I have several compact inflators that are much smaller than this since they don't have the massive battery this contains. The inflation features of this unit are at least as good as my smaller units. In particular the digital display has much larger numerals - lately I have found myself squinting in bright daylight to see the little digits on the smaller units. Also the end of the short hose that goes on the tire's valve is using a traditional lever operated clamp. I find those to be more positive and quicker to get attached than the small plastic thread on tips found on smaller inflators. Just about all of my use for an inflator is for a large motorcycle so the chances of me taking along this bulky VTOMAN unit are slim, but no excuse not to have it in the car.The unit arrived with about 50% capacity showing on the battery's charge. Using the USB-C port I connected it to a household charging bay and I lost attention after 3 hours as it was still flashing the last segment on the readout. I am guessing about 4 hours is what it took to top up the battery.The booster cable being 8 gauge on this is not a concern for me. The length of the cable from the VTOMAN to a vehicle battery is so short and it is still thicker than the wiring in the car itself. As long as it is pure copper and not copper plated aluminum I don't think I'll be disappointed.The clamps that they use are hands down the best clamps I have encountered on any cable of mine. The force of the springs is perfect - not a fight to squeeze them open if you don't have big issues with your grip strength yet they put a good amount of force on the teeth, which take a good grip on terminals. So many booster cables have weak little clamps with smooth and thin metal contacts that can be prone to slipping off repeatedly.The white 'flashlight' strip is fairly weak, at least on the product I received. It was emitting only what would be useful compared to having no light. It is like a fluorescent night light with that kind of colour emitted and a short effective range. No worries - at least they thought to include something for emergencies.The instructions on how to use this are printed clearly on the bottom of the case and a briefer list of steps for both inflation and boosting are printed on the large black plug on the end of the booster cable. Having the steps always available is certainly handy for the amount of times I would be needing this I like to triple check I have everything correct before hitting the ON button. If someone else is out with the car and get in trouble they should be able to figure it out safely as well.

Super

TLTR - You can't go wrong with the VTOMAN X7 if you don't need fast charging. Both units seem solid and capable of doing the job, but the VTOMAN X7 has better build quality and ergonomics.I've purchased several lithium jump boxes for myself and as gifts. The most challenging engine has been my dad's 4.3L V8 Lexus with a completely dead battery, and even the GOOLOO GT1500 jump starter handled it easily. I decided to get a couple jump starters with air compressors for my vehicle and my wife's vehicle. I got the VTOMAN X7 for her because it did well in the Project Farm comparison in 2023. I got myself something a little less established figuring I'd return it and get something else if it didn't work out. I got the TREKURE BETA07 for myself. Both claim to be able to handle 10L or larger gas and diesel engines, so I won't be focusing on the jump starter component of these devices. Both companies sell multiple devices, and these are both their top of the line device.Comparison: The X7 is more established with a 4.5 rating on Amazon based on over 1900 reviews. The Beta07 has a 4.9 rating based on just over 50 reviews. Both have a "list price" of $190, but can be purchased closer to $100 with the X7 being slightly higher. The X7 has a nicer build quality and appears more premium, while the Beta07 appears to have a more rugged looking build. Based on published specs, the Beta07 has a larger battery than the X7 99.16Wh vs 88.8Wh, however the X7 is noticeably heavier, so I'd expect it to have the better battery. Both come with cases, but the case for the Beta07 is a little nicer, and it comes with gloves which is a nice touch! The air hose on the X7 is easier to attach because it is free spinning at the base while you have to rotate the entire hose with the Beta07. The air compressor in the Beta07 is noticeably quieter, but the air pressure seems to measure about 1 PSI high. Both compressors work well. The form factor of the X7 is easier to use because the hose attaches to the top. You can set it flat and still reach the valve stem even if it's at the top. Depending on the position of the valve stem, with the Beta07 you may have to hold it or let it hang from the air hose. Ease of use, the Beta07 may be a little more intuitive if you don't read the manual, but I found the X7 a little easier to use.I don't understand why more jump starters don't support fast charging! My almost 3 year old GOOLOO GT3000 and my 2 year old Lokithor J401 both support 2-way 100W fast charging. The X7 supports 18W "fast" charging, while the Beta07 supports 45W 2-way fast charging.One comment on the jump starter cables, I prefer the Beta07 having the electronics inside the jump box (Like my GooLoo and Lokithor mentioned above) instead of at the end of the jumper cables. It's just a cleaner look.Conclusion: I'll be keeping both of them. They each have their pros and cons. However I will say if VTOMAN releases an update to the X7 with 2-way fast charging for around the same price, I'll buy it and give he Beta07 to my son or one of my nephews. With 2-way fast charging, integrating the jumper cable electronics into the main unit and making the compressor a little quieter, the X7 would be perfect.Note: I only needed 2 devices, but my third choice was the YaberAuto YA90 which has a rating of 4.8 on Amazon based on 800+ reviews. I'm not sure why I didn't pick it over the TREKURE Beta07 (maybe because the TREKURE was $10 cheaper and came with work gloves), but it appears to have similar build quality and form factor, and 2-way 65W fast charging.

I bought this based on a Project Farm recommendation last year. I have had several occasions to use it this year and it is still the best jump starter pack I have owned. (I am comparing it to the highly regarded Weego 70, as well as an assortment of other jump starter packs I have bought over the years.)1. Power Output - 10/10 - this is the only jump starter pack that has been able to start up every single car, minivan, van, truck, etc that I have used it on - regardless of how hot or how cold the weather is. Nothing is more embarrassing than telling your neighbor you have a jump starter pack, only to show up with it, and it isn't powerful enough to start their car. The X7 has been flawless for me, starting every single vehicle I have tried it on.(Objectively speaking, Project Farm measured the max output for the X7 as 570 amps at 8.4 volts, or 4788 watts. This was right in line with some of the best jump starters out there.)2. Air compressor - Has been working very well for me. I have used it several times, to top off numerous tires in succession. Project Farm tested the gauge and found it to be accurate. It has never overheated. The compressor speed seems fine for me, but I have never used it for any especially taxing tasks. Just topping off a couple PSI in each of my tires. (The air compressor cable is detachable, so if I think you could also screw in a longer cable if you wanted to try it.)3. Ports - Unit recharges via USB-C up to 18W. It also has two output ports - 1 USB-A 18W (5v/9v/12v) and one 5521 DC jack 15V 10A. (Very nice that it goes up to 15V.)4. LED Light - pretty standard on every battery back these days. But its bright and comes in handy every so often.5. Safety Features - I'm still a bit of a novice at car repairs so I appreciate all the built in safety features that could help protect me if I do something dumb. The manual says it has over-charge, over-current, short-circuit, reverse-polarity, low-temp, high-temp, over-voltage, over-load, spark-proof, and reverse-charge.Hope this information is helpful! This is a great unit, and I am extremely happy with it!
