BEATIT QDSP 2200Amp Peak 12V car Jump Starter (Up to 10.0L Gas and 10.0LDiesel Engine) 21,000mAh power bank With 100W 110V portable power station inverter for Outdoor Adventure Load Trip Camping Emerg

Compared to battery car starters I have had in the past this is small and light weight. I've had a Tesla Model X for almost 4 years now and one of the few issues I have experienced is the 12v battery going bad which causes various issues for the car including not being able to start it, same as in a gasoline car. Saw this Beatit 12V car Jump Starter on sale on Amazon a couple weeks ago and it sounded like a good idea especially since it also has a single 110v outlet and 2 USB ports.Been playing a bit with it but haven't had the need to jumpstart a car with it yet but I did hook up my multimeter to it. Fully charged I got 109.5v from the AC outlet and 16.6v DC from the the engine start cable output.The blue USB port (5v/9v/12v) worked well in charging my iPhone 11 Pro Max. I used a USB port meter which showed the black 5W USB port puts out 5.14v/21mAh and the blue USB port labeled 5v/9v/12v puts out 5.13v//21mAh.I tried using the 110v outlet to charge my 2019 Macbook Pro and that didn't work since my Mac would notify as charging and then stop charging immediately and cycle through that continuously until I turned off the AC outlet. So this outlet isn't able to provide quite enough power for a large laptop. The inverter outlet worked fine powering a lamp with a 3way bulb up to 100 Watt. At 100W the Beatit lasted about 45 minutes before the LED meter on it showing 1% charge. The case was very mildly warm to the touch after this. Then plugged in with the power adapter and it has so far taken almost 2 hours to get to a 50% charge, and about 3.5 hours to finish fully charging.I like that it has an on/off switch for the device and both a button to turn on the AC inverter outlet and another button for the DC outputs. Less likely to drain the battery by accidentally leaving the outlets on.Will have to check this over time to see how long it holds a usable charge until needing to be recharged. Only way to charge it is using the 110v power adapter cable included. Would be nice to be able to charge using an auto cigarette lighter plug or USB cable so it can be left charging in the car for when it is needed.

- This is a very nice powerful vehicle jump starter for the price & has many handy features built in. Such as the AC and DC power along with the single 110v outlet and 2 USB ports. Even a power converter that’s great in an emergency situation and portable 12V tire inflator as well as using the 110V side to plug in a lamp using a 50 watt bulb. The built in light is very bright for those dark nights. It’s quite amazing to have an inverter also built into this product. This should have no problem jump starting all kinds of cars as well at trucks. It is very well made and solid product. Compared to other battery car starters I have had in the past this is small and light weight. I love that it even comes with its own personal durable hard case that keeps everything together and safe.

This would be a great addition to anyone's Emergency kit in there vehicle which is exactly where this went, I will never have to worried about being stranded somewhere without power ever again.

Tried using multiple times and never was able to get it to work. Complete junk!

I want to describe my use so far of the BP101 jump starter and not a lot of detail on how to use it. The BP101 came with the described items. The wall charger, cigar lighter, jumper cables and a nice carrying case. I charged my iPhone from 50% and it used about 30% of the BEATIT charge. I attempted to jump start an 8 kW electric start generator and this jump starter spun the engine over like it was nothing. Makes sense since it's supposed to start a diesel engine. The generator didn't start so it still needs some work. The flashlight is a nice feature but I don't see me ever needing an SOS or strobe light function. This is why I wouldn't buy it to use the AC power outlet. I turned on the AC outlet to see the discharge it had on the jump starter. It ran the BP101 battery completely down from a fully charged state over night. I connected a KILL A WATT EZ to it and saw that it was putting out about 114 vac, a frequency of 63 hz and power factor of 1.0 with no load. I plugged the fireplace logs fan into it and checked it again. With the fan running it showed 116.6 volts, 65 hz, .59 power factor, .65 amps and 46 watts. I'll let the electrically trained comment on these numbers but don't like the high frequency. Bottom line, even though I don't like the 110 volt inverter I think it will function fine for what it was intended to do which is jump start engines.

Bought this 2 weeks before a 3 week vacation in the high deserts of Southern Utah, mostly in remote areas with no cell service as a back-up. It only has a 30-day return window, so when I got back 5+ weeks latter. Didn't work the one time I needed it and had to get a normal truck-to-truck jump start. When pugged into the charger the charge level never went to 100%, stuck at 99? Didn't have a way to test it on my diesel truck without extensive work (drain batteries?). I now realize it never charges past 99%, but as soon as you unplug it from the charger, everything is dead on it? I also agree with other comments about it only being able to be charged from 110 AC? It would be nice to charge from a DC. Update: contacted mfg customer service. A little odd to work with through email, but they did send me a replacement which seems to work as advertised. still trying to figure out how to test on my diesel truck?
