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: 01-07-21
I 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.
