JF.EGWO 3000Amp Car Jump Starter with Air Compressor, 150PSI Tire Inflator with Digital Screen Pressure Gauge, 24000mAh 12V Auto Battery Booster (9.0L Gas/ 8.5LDiesel Engine), 2 USB Port 2 Light

This review is for the JF.EGWO 3000A Peak Car Jump Starter with Air Compressor. I have fully tested all features *except* for the actual jump start feature thus far. I have a weak battery in one of my cars, and it should go dead soon since I am not driving it very much. Once it has gone dead, I will attempt to jump start it, and will update my review here.Regarding all of the other features, after fully charging the unit, I thoroughly tested the air compressor (and its auto-stop feature) on 8 passenger-car tires. Four of the tires only needed 2-3 pounds of additional air, but the remaining four tires needed 16+ pounds each, because they had been sitting unused for a long time. This was a very good workout for the air compressor, and I used the air hose extension with quick-connect that came with the unit. The digital display has a bright blue backlight, and is very easy to read, even in direct sunlight. It was very easy to set the desired inflation pressure, and once the hose was connected, it immediately displayed the current tire pressure in 0.5-PSI increments. I found, surprisingly, that the desired pressure setting was adjustable from 5 PSI to 150 PSI, even though the unit is only advertised to support 120 PSI max. Although the 8 tires that I inflated only needed to be inflated to 32 PSI, I also inflated a large donut spare tire, which required 60 PSI. As anticipated, the compressor shut off automatically once the selected pressure setting was reached. This is very convenient, because you don't have to carefully watch to make sure it doesn't over-inflate your tires! I completed inflating all of the tires in about 15 minutes, which happens to be the maximum run time for this compressor before allowing it to cool off for a while, according to the manufacturer. It showed no signs of faltering or laboring during the entire time, not even with the 60 PSI spare tire. It did get pretty warm toward the end, but never got alarmingly hot. The battery meter had dropped to 50% after I was all finished. I checked all the tires with a high-quality pressure gauge afterwards, and they were all exactly 1 PSI above the desired pressure that I had set in the unit. This is very reasonable precision, and I was notably impressed.After recharging the unit, I tested the two USB ports, charging a phone and an iPad simultaneously, and it worked great. I did not have to turn the unit "on" in order to charge these devices; I simply plugged them in and it started charging them. It should be noted that when the jump starter unit itself is being charged, it will NOT provide power to the USB ports! It needs to be unplugged from the charger before the USB ports will start providing power. This is an annoyance, but something that I can live with.The built-in LED flashlight (with two LEDs) works very well, and is surprisingly bright. Because this unit is so light-weight (less than 3 pounds), I was able to use it as a hand-held flashlight while walking around outside in the dark. The manufacturer claims that the light will run for 100+ hrs on a full charge. The light has 3 modes: Solid on, "SOS", and fast flashing. The "SOS" mode tries to flash the Morse Code for "SOS", but in actuality flashes "HOS", which I found to be kind of amusing.The bright white digital battery meter on the side of the unit can display 5 different values, and these may be a little misleading at first glance. Here are the values that it can display, and what they actually mean: 100% = 80-100% charged; 75% = 69-79% charged; 50% = 40-59% charged; 25% = 20-39% charged; 0% = 2-19% charged.When you are charging the unit using the AC adapter, the display on the side will flash "IN", indicating that current is going into the device and charging it. As mentioned above, while "IN" is displayed, the USB ports will NOT provide power. Once the display shows 100%, you need to keep charging it until the "IN" indicator stops flashing. Otherwise, you may actually only be at 80% (see above). When you unplug the charger, the display shows "OUT", which means that it can provide power to the USB connectors. The power meter display will shut off automatically after 3 minutes, but the USB connectors will continue to provide power.I tested the in-car charging cable, which plugs into a cigarette-lighter outlet, and found that the "IN" indicator comes on during charging, but does NOT flash, unlike when using the AC adapter. I found that it charged in the car just as fast as it did with the AC adapter, and the display eventually showed 100%. Because the "IN" indicator does not flash, however, I don't know how to tell when the unit is truly charged to 100% capacity.A black nylon bag was included with the device, with pockets for the unit itself and all of the included accessories. I had no trouble fitting everything into the bag.Everything was packaged in a small sturdy cardboard box, with tamper-evident tape seals. The unit itself was wrapped in protective bubble-wrap inside the box.The manufacturer seems to be motivated to sell these units, and included a couple of small gifts: A small silver-colored "horseshoe" pendant (perhaps for a necklace or bracelet), and a rather nice USB-powered reading light. I found this additional light to be useful, as it is not as bright as the built-in light, and is flexible so you can bend it and point it where you want.As I mentioned above, I will update this review once I have tested the jump-start feature.UPDATED: 01-07-21I tested the jump-start feature by purposely leaving my headlights on until my battery was totally flat, and it worked perfectly. The car started right up on the first try. The indicator on the side of the unit still says 100% (which we know means somewhere between 80-100%). I'll be ordering another one of these for my other car.

The unit has good battery life. I was able to charge 3 vehicles (12 tires) and still had over 50% battery life. It filled the tires efficiently. Tires that only needed a few PSI charged in 15-20 seconds. I had a tire that needed about 11 PSI and it charged in 60 seconds. I had read complaints about the noise, but it is similar to every other electric air pump I've ever used. The jump starter works as it should; I jumped a 6.2L V8 with it. Overall, I'm very pleased with it. The carrying case keeps all the accessories together with the unit.

Item was as advertised. Packs a punch for a small size. Plastic case does seem like it might crack easily if dropped on pavement, but otherwise is sturdy. Canvas carry case is a little small with all the accessories in it, but works. Plan to keep in my car for emergencies, and like to not have to depend on another car being around for the traditional jump start. But, I have not actually used it for a jump start yet, will have to trust it for that! As an inflator: Worked very well for "topping" off pressure in car tires. Instructions say not to run for longer than 10 minutes then 5 minute cool-down, so wouldn't use to fully inflate multiple tires. Overall, assuming the jump starter works as advertised, it makes a very good addition to a cars emergency kit. Have not had it long, so I have nothing to say about battery life or how often it needs to charged.

The amount of times this compressor has saved me from embarrassment, I cannot count on 1 hand. I have been saved from dead car battery, almost flat tires, power outages (it has a flashlight). This little compactness is so so very convenient. Every female need to have this in her car so that men know we can pump our tires too lol

Just bought this jump starter + air pump, I have tested it couple of times and it is working great so far. I intend to use it for a few more months and update this review accordingly. I like the maximum current 3000A capability of the jump starter and also having the digital indicator for the air compressor. It has two chargers , one for in home charging and one for in-car charging. I received a defective in home charging first but then I replaced and received another one. Overall, the product has a good quality feeling to it.

This air pump is awesome. One of my SUV tires was about 7 pounds low and this pump aired it back up very quickly. I say a minute or less. I was amazed. I checked the pressure with my air gauge and it was rather close to the pressure the pump said it was. Have not used the jump start yet. Mine had 75% charge when I got it and it charged to 100% rather quickly. I am so glad I bought this.

Update 6/6/24 I have down graded my review due to durability of this product. After 3 years of very light occasional use the AC charger stopped working. The unit will only charge to 50% with car adapter.Update:Had a couple chances to use this recently. Grandsons bicycle tires, my motorcycle tires and jump start my weak battery on my motorcycle. I will never travel on my bike without this thing. From simply and quickly setting my tire pressure to emergency jump starts this item has you covered!! Worth every penny!!Exactly as described. Bought it to put in my motorcycle travel pack just in case of emergency. Could not be more pleased. Will use it on camping trips too! Easy solution to top off air pressure of camper tires at storage facility.

I bought this to replace my old jump starter/inflator. This one is more powerful, and 75% smaller. I’ve used this to inflate tires, and it works very well. I haven’t jump started a car yet, so I can’t attest to that aspect, but I imagine it will work. I have tested the lights and they are VERY bright. Overall, very satisfied with my purchase.
