Tyrell Chenergy 2200 Amp Car Jump Starter with Air Compressor,Portable Power Station with 260 PSI Tire Inflator,400W Power Inverter Dual AC/DC Ports,2.1A USB Port,Battery Clamps

I've tried out several "jump packs" like this. I consider most just a battery with jumper cables (and perhaps a few other features like light, 12V outlet, etc). I like to describe it by the battery rating, like 22 amp-hour for this one. Many may be impressed by the "1700 peak amps" advertised numbers, yet all brands say in the manual things like "Never crank a car engine for over 5 seconds or you'll damage the battery" to show how long it can handle even ~100 amp draw (and how unreal that 1700 is). So don't expect that much from it. If running things that need constant power, then remember it'll supply 1 amp for 22 hours, or 2 amps for about 11 hours, etc (as the "22 amp-hour" implies). Also don't forget to "recharge after any use as well as every 60 days when not used" as the directions give. They say to "Only use our AC charger on it" which does seem to regulate the power sent to ~14.5V. So you could leave that plugged in 24/7, yet you shouldn't need to do that making me suggest get a timer to come on for 15-30 minutes a day. That way it's not literally charging constantly, but you don't have to routinely plug it in yourself either and it will get topped off constantly. My best example of jumping a car happened a few years ago where a buddy called saying he left a light on all night (so the car battery was totally drained). He had a 4 cylinder car, so I first tried a pack labeled for it with just a 10 AH battery. It made the dash lights come on with the keys in, but couldn't crank the engine at all. Not surprised at it not being big enough, I removed it and tried another pack with an 18 AH battery. It could slowly crank the engine, but still didn't start his car. So I then went to a 3rd one like this (with 22 AH) that got him started. Some may view that story as "The last one was the only one that worked", yet they all gave some power showing progress. I think of the car battery like a 5 gallon bucket and it took more than 1 pack (like a 1 gallon bucket) to even half-way refill the empty 5 gallon. So one pack alone can fail to get you going depending on the car battery conditions (yet it may start a car with the lights on for an hour while having dinner or such). The light and compressor are good features when needed. Don't hope to need them, but nice to have. I've actually used packs like this more for power while camping (like run an air mattress blower etc) rather than jumping cars every day. Also this does have the "reverse connection alarm" where you connect the clamps with the switch off, look for the green light on the pack (and/or no red with beeping), then turn on the switch if it's correct to do the jump (or remove them if you got the red before any damage happens). This isn't 100% "fool-proof" where you could still turn it on when wrong, but it does give you a confirmation before starting (unless the car battery is at 0V, then you need to double check it). Note, some packs require ~3V or better power from the car to connect up (and won't do anything if the car battery is 0V), so this will still work in that situation (while the others won't). One thing I like about this one better than many is the way the "Battery status" lights work. Many packs have a % display or the LEDs come on with the battery at certain voltage regardless of conditions. The voltage level does give you info, but you want to see different voltage levels when charging versus using the battery. On this pack while charging (with power on the "charge" port), the red LED comes on while below 13.0V, the yellow LED comes on between 13.0 and 13.25, the first green LED comes one between 13.25-13.5, and the second green for "full" comes on above 13.5V. That is exactly what you want to see while charging (like 13.0V is very low while charging). After charging and while running things (with no power on the charge port), it follows that pattern but drops the voltage 1V lower on everything (red below 12.0V, yellow 12.0 to 12.25, etc). Again that's exactly what you want to see for that condition, yet if it just had the red below 13.0V (like charging mode) it wouldn't tell you anything while running things. So I like how it "switches" for the condition you are in to give you the details needed. If you understand the voltages under the conditions, a voltage reading is good, otherwise this is better than many. Overall these aren't a sure fix for every situation and you don't want to have to open the hood every time you go to the car, so if the car battery is going bad, deal with it. Otherwise for the once-in-awhile situations it may get you out of a bad spot.

The first item had a little glitch. Reported it to the company and they sent me a new one within a week. Warranty is honored quickly.

I love this. It gives me an extra sense of security. Not only am I able to jumpstart my car or anyone else who needs a jumpstart. I am also able to use the air compressor as needed. The power generator has got me out of so many binds it is unreal. Having that bright of a light at night is great. Having the USB ports is always handy. If you are a little old lady, or a little old man who cannot lift very much, this may be too heavy for you that would be my only thing to warn you about because this is a sturdy multiple use machine and it is great for the car. If you want to know that your loved one has an extra sense of safety and security by one of these that way, you know if they get a flat it’s taken care of if their battery goes dead it’s taken care of if they get stuck on a snowy road they have power this is that extra sense of safety and security that we all need when traveling. I would suggest getting a 12volt to a 110 inverter. They are a cheap investment and it adds so many options.

My husband keeps the keys to our car in his pocket and often when he sits down, the trunk to our car opens and the light drains the battery overnight. I am trying to get him to leave his keys on the hook by the back door instead of cramming them into his pockets, but until he's trained, this thing has been a LIFESAVER for me. We've jump started our car at least four times so far, and as long as the unit is fully-charged, jumping is seamless. The compressor is great for topping off tires. Worklight is nice & bright. USB prots work well. And LOVE having portable AC jacks! Only downside is cables are about a foot too short, but I can work with them as is. Great value for the money.

This little Swiss army knife of a battery works great. I have collection of vintage cars and bikes that sometimes sit for a few months till they get driven. It has helped me out more than a few times so far with dead batteries and low pressure tires. I have not tried the AC power adapter but I am very happy with the other features of this battery pack.

The product worked well until this past weekend when it quit working all together. I emailed customer service more than 24 hours ago and haven't heard back yet. On the product page it said they offered customer service for a year and this was purchased in December 2023. It has been more than 24 hours since I emailed.

We bought this charger specifically to be able to jump start our diesels. The first time we got the chance, I tried it out and it didn’t do it. This was on a 7.3 powerstroke for reference. The starter is actually an upgraded starter that cranks quite fast, so I’d like to rule out the normal bad starter drag. The truck was not completely dead, as in, it would still crank, just too slow to start. I put the jump pack on it and tried it- no luck. I tried leaving it to “charge” for a little bit and it still made no noticeable difference in its ability to start. I ended up having to get a second vehicle to jump it and it fired right up. We tried it on a Chevy 4.3, and it did start it but it didn’t inspire much confidence in its ability. Both times the jumper was completely charged. I’ve used it to jump smaller things and I have used the air compressor on my smaller car tire and it worked fine. This seems like a good jumper for around the house- start a small motor or pump up a tire- but it absolutely will not start a bigger diesel as the description says.

Lo mejor de lo mejor para q nunca te quedes votado en tu auto, calidad sobre todo, compresor de aire, linterna, carga rápida con dos cargadores diferentes, se lo recomiendo al 100 %
