 The Mack Daddy Mar 10, 2010
By Shubooti
This the Big Mack Daddy for sure! I was weary after looking at many many choices, but finally chose this one because of features and reviews - hoping I wouldn't be disappointed when it arrived. And I wasn't! I didn't have the ON/OFF switch on the jumpstarter on previous units, and really like this feature. You can hook up the cables on your battery, and get a confirmation that the cables are connected correctly (LED lights) without any power on the cables - then switch on the power after you're sure all is connected correctly. And the unit has plenty of power to start any but the largest of engines. The built-in LED light is powerful and lights everything under the hood or around the car. The unit is also perfect for usage in the home during storms/power outages with an inverter to power small AC appliances, as well as a DC outlet, and a USB outlet as well. With an AC power strip and a multi-port DC splitter you can power (or charge) several units at once.
Features:
1. USB power port
2. USB power indicator
3. USB/LED power switch
4. Charging indicator
5. Charging Jack
6. Battery level indicators
7. Battery level test button
8. Battery connection (correct hook-up) indicator light
9. Reverse polarity indicator light
10. 120 volt AC power on/off switch
11. 120 volt socket w/cover
12. LED work light
13. 12 volt DC socket w/cover
14. Jump start power on/off switch
15. Red positive battery clamp
16. Black negative battery clamp
17. Carry handle
18. 15 amp fuse
19. Air compressor gauge
20. Air compressor on/off switch
21. Air compressor hose compartment (with actually lots of space for a change)
22. 260 PSI air compressor
23. Nozzles for air compressor
24. 120 volt AC charging adapter (to recharge the unit)
25. Owner's operating manual

Incredible! Feb 13, 2010
By Eve
I need a new auto battery, but for several reasons I'm not ready to buy one just yet. My car needs a jump start almost every day I want to use it, and I can't depend on my husband's car being always available. I decided to invest in a Cobra CJIC 350 Jumpstarter Powerpack because I can use it to start the car, take it with me as backup, and because its many uses made it seem like a valuable item to have in a disaster or other emergency. I did a lot of research, and this product has the power, functions and price that most appealed to me. But there was only one short review that wasn't specific... I took a chance anyway and bought it.
I'm delighted to report that it functions exactly as described by the manufacturer. I've tested all the functions listed in the product description. All performed as advertised.
When it arrived in the box it was almost fully charged already. I plugged it into household electricity and it reached capacity charge in less than 1/2 hour. After I tested it by jumpstarting my car(V6), plugging various appliances into it, using the light, etc., I charged it to capacity again in less than 15 minutes.
In the two weeks since I charged it last, I've inflated all four tires from 25 to 30 psi, and jumpstarted the car 9 times, and it STILL isn't even 1/4 down from a full charge! Do I love this Cobra? Oh yeah.

 Wears out quickly, mostly useless Jul 23, 2010
By Bruce Carlson
I purchased the unit partly to take around in the car, mostly for portable emergency power on long trips through wide open country, partly for portable convenience power when traveling by car, and partly for in-house emergency power (in case a storm knocks out the power.) It takes 24-30 hours plugged into a wall outlet to completely charge the unit from an "empty" state. (The charger is a separate power brick, so be sure to take it along if you're on a road trip and need to recharge.) At first, when not in use, it held that "full" charge for about two weeks. The auto power port (formerly known as a cigarette lighter), USB power power (good for charging an iPod or similar device), and 3-pronged 120 VAC outlet (for running just about any normal household device) all worked fine and could run various low to medium powered appliances for several hours from a full charge. The the built-in air compressor is handy for re-inflating tires that are low. Haven't actually tried the built-in jumper cables on a car with a dead battery yet. The built-in LED light is handy for using the device in the dark, but the unit's far too heavy to be used as a common flashlight.
After just two months (with no actual use beyond initial try-out), the unit can no longer hold a full charge for 24 hours when not in use. After charging for a full day, the power now tests "low" after only 12 hours of non-use, and "empty" after two days. The only way it can be used as emergency power is if it's kept continuously connected to charging power (120v wall outlet.) It's not much use packing it around in the car anymore; even if it was fully charged in the morning, by dusk it will be "low" and it won't power anything for long.
I consider this purchase a complete waste of my money.

Cobra cjic 350 Car / home survival tools Jul 09, 2010
By Croppled1
Eve did a wonderful reveiw so I will just add where I can see some points to help someone .
First you always get what you pay for . This is not as good for starting cars as the Jump and Carry but its great for the average person in average circumstances . For one thing the cables are very short and mine came with a newer 900 peak amp starting rating . Anyone else not have the 1800 sticker on the front ?
I also noticed mine has a 14 amp sealed lead acid battery its not a AGM like the jump and carry which is 18 amp . This one has a small reserve battery too
One of the most important features of this unit is you can leave it plugged in and it has overcharge protection in it's power cord . Thats a deal maker .
The air pump isnt a Viair 70p it takes 5-10 minutes to top of a tire , vibrates with moving parts , very loud , but it works and would help you fix a flat on the car if you have a tire plug kit and a pair of pliars to take out a nail or screw from tread
There is room in the back where the hose for the tire pump is to put the charger / a plug kit / the two inflator nozzles and I can see where the door might not always remain closed in time so also a small roll of tape to tape it shut .
The set up is very nice and well thought out . I had thought it was a larger battery and hoped it was more advanced but this is good . Its old tech and thus thats why the reasonable price . I will add on later on wear tear and how it works . However I figure I pretty much know . If it runs my laptop for 4 hours between charges I will be happy .
I was suprised this unit does not come with a DC charging cord . I thought if you bought a line with two male ends on your own it would charge that way but there were no references to this . I did see a reference to using DC and found my old chargers one worked but no other info on where to buy one from Cobra . I was dissapointed but not a deal break for me I just have to share the one I have between two units now . I also have a generator for campling / power outages so whenever I run it I will also charge the this up its a niche tool so you not have to use jumpers or a generator for small things . Very nice unit for personal all around use . If you want to jump dead cars more then have a storm / car utillity tool buy the Jump and Carry where you can replace the batteries too and get a lifetime warranty for battery replacement onetime . This one ..when the battery dies or sulfates so the charge time is less and less you just toss in the trash .
I would recomend it to everyone ..it should be in every car and thus home when you are for when the power goes out . I am disabled and wouldnt think of not having one . I run a 12 volt fan when camping/ power outages with it and the light is nice too .Perfect for filling bike / lawnmore tires over getting out the compressor.
However for people really into starting cars and filling large tires and infatables buy the 660 jump and carry with a Viair portable `12 volt pump .. it may cost more but you will be amazed its 4 times the power and air volume . Instead of 40 minutes with rest periods to do the tires you will fill them in 10 . Current cost though would be about $100 more then this set up . This is perfect for a passanger vehicle in all but the worst weather with a weak battery or if you fill smaller items then 32 inch tires regularily . Take care .
I just came back mine is still doing well I leave it pluged in all the time and dont use the DC cord much because remember the overcharge protector is in the adapter . Used it several times the past winter to jump my car as I am disabled and it discharges the battery often if I don't get a good connection with my trickle charger and I use it to fill the tires on the lawn mower , cars and fill up small play items like basketballs with its adapters . I also have used the lamp and inverter it can power my laptop with a digital antenae for a few hours easily . Great for the kids room with a LCD night light who you don't want to use candles in a outage . Will power a 1 watt night light for days on a full charge but it has a 4 watt inside it . I think this is a must have for camping and the storm survival kit . Money is best spent on a generator for power emergenc power supply .

Won't even start my lawn tractor. Oct 01, 2010
By lineflat
Got it, charged it. Says the battery is full. The light on the front and the compressor seem to work. But I tried to start my lawn tractor with it, and absolutely no juice. The indicator says it is hooked up properly, but it doesn't look like any current is coming out of the jumper cables. Even the headlights on the tractor didn't get any brighter when I hooked up the unit. So I charged the tractor battery for 15 minutes with a speed charger, and it turns right over. So even with a partial charge in the battery, this thing couldn't start a little lawn tractor. I guess I won't bother with the car.
Oh, and their tech support is not toll free, so you get to call and be on hold for long distance charges.
Enjoy.
