@Achromatter I have, at least a half dozen times (not with this particular model, though – see my post below). Batteries were too drained to even get a good click from the starter – but still not completely “dead” – and started my car(s). YMMV.
@Achromatter they work fine but the weaker ones like this are met for smaller engines and usually when the battery is not completely dead. There are more expensive ones with more cranking amps for larger engines.
@Achromatter yes, and they work (depending on your engine size). One like this should crank any 4 cylinder and some v6s with no problem. For v8s or diesel trucks, look for a larger unit with maybe 600A or higher start current.
I used a 10,000mAh unit instead of buying a lawnmower battery for a whole season because I kept forgetting to buy the battery after I’d successfully mowed the yard. I got many starts of that little 23hp v-twin before having to recharge, but I eventually remembered to just replace the damn thing.
A lithium jump start pack should have no problem holding a charge for at least 6 months. These type of batteries have very low self-discharge rates.
@Achromatter@djslack curious if anyone has any luck with these in winter? It would be a nice thing to keep in the vehicle but I am afraid the below freezing temps may be harmful for the rechargeable battery. I know my phone battery doesn’t like the freezing temps.
@Achromatter These work. They are no replacement for a commercial quality jump box but it is actually quite amazing that these can start a car!
As a professional Auto Technician I’ve used my fair share of these kinds of units. I’ve even bought several “cheap” ones like this to try them out and to give them out as gifts.
With that being said though these do have some shortcomings:
1> Don’t expect it to start a large engine, or a diesel. There’s just too much engine to crank over for this little guy to handle
2> Don’t expect it to start a car with a frozen battery, in very cold climates, or with a completely dead battery that has been sitting around for several months.
3> Don’t expect it to last a long time. Battery quality on these inexpensive units tends to be extremely hit-or-miss, and jump starting a car is VERY stressful on these batteries, especially on smaller units like these. Once in a while in an emergency is fine… and using it as an auxiliary battery to top off your phone, tablet, etc is also fine… but don’t expect the battery to have a very long lifespan if you’re using it to jump cars several times a day. In that case you’ll definitely want a more professional grade unit.
4> These don’t take any abuse whatsoever. Once installed don’t crank on the starter for more than 3-4 seconds at a time, or if the engine doesn’t want to turn over smoothly. You’ll burn up the wiring in this thing in no time flat.
5> The soldering on the circuit board for the safety device (the plastic box on the positive cable) is likely to be of VERY POOR quality. I suspect it was done by 5 year olds in China. Because of this if you pull on the wire during or right after using it it’s likely to just pull apart as the solder will get hot enough to melt and it’s really all that holds it all together in there.
BUUUT… for $35 as long as you know its limitations it’s really not a bad deal. It’s nice to have around for emergency jumping as needed or to recharge your phone. I actually have an extra one mounted to the side of my tool box that comes in handy for applying 12v and ground to test automotive motors (window motors, etc), light bulbs, and what not… and it’s also handy for igniting Airbags before properly disposing of them!!!
IDK why the powers that disappoint here at Meh didn’t display any price comparisons from any online retailers, —unless maybe it’s because everyone from Amazon to Walmart has these jump starters for $19.99?
@PhysAssist Feel free to post the closest comps you can find for 10,000 mAh jump starters with the various cables/connectors. This specific model is only sold in Canada, which didn’t seem very helpful, and jump starter specs are so all over the place I couldn’t find anything that felt apples-to-apples, hence the ¯\_(ツ)_/¯
I have several brands of these for family vehicles, even one for my motorcycle (think I may have got that one from Meh, but am too lazy to check), so don’t need another. But, to those not familiar with these devices, I definitely recommend having one (but I am not at all familiar with this brand offered tonight, so do due diligence). It beats having to bum a cable jump from some stranger, I can tell you from personal experiences.
@hchavers because you are using jumper cables to temporarily connect two different electrical circuits, the same way you use a jumper in any electrical circuit. And you are doing it for the purpose of starting a car
@hchavers Because you are using jumper cables. BTW you are NOT “recharging a car battery” here—that battery is still dead, if the engine stalls the car battery will not restart the car. (From experience at -20F). And these things (in general, IDK about this specific model) are wonderful, handy, small and low self-discharge rate.
I see a little pod on the cables that indicate that it’s at least fused, but the ability to spark the cables like that indicates that there isn’t any short circuit or likely reverse polarity protection on this unit. If you short it out or reverse polarity get ready for the great possibility of an exciting fire event. I lost my first lithium jump starter (bought here) to that, but I’ve since replaced it and gotten more that all had circuit protection devices built in.
That first pack was 7500mAh but stated 400A max. It jumped my wife’s Buick (3.6L V6) from dead with no problems.
The carrying case for this one is nice. Some come with nothing at all, some with soft zipper pouches, and I’ve even gotten one with a velvet drawstring bag. A hard case you’re not afraid to toss in the trunk on a road trip is a plus.
Nice hardshell case. Good utility features beyond ‘jumps a dead battery’ unitasker.
One thing - check every 6 moths for a charging topoff. Although keeping batteries at full charge long term and in heat reduces max capacity and longevity. Best to think of this item on a 5-year replacement schedule.
One work of caution. Don’t charge these babies up and store them in a hot car thinking you’ll be good to go. The high car temps will eventually render the lithium battery useless. Same goes for a phone.
@Kidsandliz@lhroller It’s not all that bad just being stored at those temps unless you’re charging it at the same time. My oldest unit is at least 5 or 6 years old and has been in the car all that time except when brought in the house for charging and is still working normal. I bought the Energizer jumper pack from Meh as a backup and it’s been in the car all that time as well.
For many people, a lithium jumper pack will likely be more useful than a traditional lead acid base model. Like me, most don’t want to deal with the size, weight and frequent charging a lead acid base jumper would need to remain useful. A good lithium pack ignored for 8+ months in the car would have a much better chance of still being able to start a car than a lead acid pack will.
I have been on the lookout for one of these. One of the requirements I have is that it has to be able to be charged using a Micro or Type-C port - this meets that requirement. The other is that it has to be powerful enough to jump my small hyundai hatchback - with a completely dead battery - its unlikely that this one will do it - Ill stick with getting the NOCO when its on sale. Maybe JNP.
@jst1ofknd you’ve reminded me that more than Instagram double pointless taps we can have a pointless conversation and agree together and be happy. I’m the last person for world peace but you make my heart and soul smile strange friend.
