Was in Target for the 30% clearance and noticed this power bank has also dropped to $48.30 in price. Same as the one previously on OZB here but with further discount:

Looks like it has selectable outputs and pins for the laptops too on top of the USB output as well as the battery jumper function. Not bad price imo.
@Dragoneye: id not keep it in the car at all for 2 reasons, one is the temp in summer inside a car is way too hot, can get well over 70c inside a car. 2 is being able to stop it from bouncing around or getting crushed in an accident.
but if you are set on doing it anyway i would try and pack it in the globe box securely. less chance of it banging around enough to break it or cause an internal short which could send it into overload. while eug has a good point in his above post you also have no idea of the quality of the balance charger or the cells in this target jump starter so imo its just as likely to cause issues as any other cheap lipo device (like the vids i posted earlier)
i guess it also depends on what car you drive, if its some $500 beater that dosnt matter if it burns to the ground then go for it, if its like some of my cars, i own 1 of 1000 ever made world wide, i wouldnt risk it even if it is only a 1 in a million chance of having an issue. i also cant remember the last time i was out and left the lights on long enough that i needed a jump while i was out, only ever needed to do it while im at home so its no problem for me to leave it at home for when i need it or take it with me on the odd occasion i need it elsewhere (like some people above who wanted to use it to power a fan in a tent, id have no concerns about transporting it occasionally)
lastly, last i knew one of the leading ideas for the mh370 crash was a lipo fire in the cargo
I think you're overblowing the risks of LiPo cells. (badum-tish!)
If you're concerned about the battery catching fire in an accident that's energetic enough to crush your boot so much that the jump starter you have in there will also get crushed, I would be more worried about the 50L of flammable petrol you're also carrying in the car.
LiPo technology is safe when used properly. We use them in phones, tablets, and laptops every single day.
They're only dangerous if the cells get damaged, charge-abused, or are of poor quality. LiPo cells use a pouch that can be more easily damaged than the metal canister of a LiIon cell - but if the LiPo cell is within a device, it can't be damaged easily.
All the common burning LiPo videos you see are of RC batteries. Those are unprotected LiPo pouches used in RC vehicles that are subject to lots of impact and charged at high rates, so it's not a big surprise that they can catch fire.
Also, just because you can find videos of something burning on youtube, it doesn't mean that thing is dangerous and you should keep away from it. If you search for burning cars on YouTube, you'll find plenty of cars on fire which have nothing to do with LiPo batteries. Yet we all still happily drive them every day.
lastly, last i knew one of the leading ideas for the mh370 crash was a lipo fire in the cargo
And another idea was that the CIA hijacked it to smuggle weapons or something. Point being, anyone can make up theories without evidence.
@eug: i do agree mostly with what you mean…… but
If you're concerned about the battery catching fire in an accident that's energetic enough to crush your boot so much that the jump starter you have in there will also get crushed, I would be more worried about the 50L of flammable petrol you're also carrying in the car.
which now has a perfectly placed ignition source within inches of the flammable liquid. but more so some of the pockets on the side of the boots of cars only take a small collision into the rear 1/4 panel to completely crush them because they are not a structural member. sure its a 1 in a million chance but if you think that means it wont happen you severely underestimate the vast number of things that happen every day….
We use them in phones, tablets, and laptops every single day.
umm, remember the dell laptop fires? but besides that, how much effort do you think target went to to ensure the charging circuit in their $50 bank they only ever made a few thousand of versus as good as what is in your $1000 name brand fone which they have sold billions of? i dont think the safety margins in them are even slightly comparable specially when it was you that said the fires i posted before were from "unknown quality" chargers?
but if the LiPo cell is within a device, it can't be damaged easily.
cant be damaged as easily sure, but bouncing around in the boot of a car for years sure could lead to it getting damaged.. again its just not a risk id be willing to take myself.
as for the rest of it, i simply bring to your attention
https://en.wikipedia.org/wiki/Plug-in_electric_vehicle_fire_…
Several plug-in electric vehicle fire incidents have taken place since the introduction of mass-production plug-in electric vehicles in 2010. Most of them have been thermal runaway incidents related to the lithium-ion batteries
.
And another idea was that the CIA hijacked it to smuggle weapons or something.
but that is a theory in which any semblance of common sense tells you is not possible, it was also not aliens or a government conspiracy to kill cane toads….. where as it was known that they were carrying a large quantity of originally undocumented lipos (originally it was said it was some fruit iirc) and that there is a good chance that it was an onboard fire which disabled the pilots so the same common sense that rules out your example rules in the lipo hypothesis, if it walks like a duck and talks like a duck, its probably not a platypus…..
which now has a perfectly placed ignition source within inches of the flammable liquid.
Cars have been catching fire without LiPos anywhere nearby for decades now. Why the sudden fear of a "one in a million" chance now? A person is probably more likely to be injured by their phone on their dash flying into their head in a crash than a jump starter in the glovebox catching fire after being crushed in an accident.
sure its a 1 in a million chance but if you think that means it wont happen you severely underestimate the vast number of things that happen every day….
I think you're severely overestimating the probability of all four conditions happening at the same time:
umm, remember the dell laptop fires?
If you think rationally, it's all about probability. Everything has risks, even walking across a room - you could trip on something and hit your head on a table corner.
There are hundreds of millions of laptops around, and only a minuscule number have caught fire. The risk is very low, so we all have no problem using laptops.
There are also hundreds of millions of cars around, and there are heaps of fatal car accidents all over the world. We all accept the risk and still keep driving.
The probability of the scenario I described earlier is very low - very likely lower than the probability of a fatal accident - so rationally, I should fear it less than driving itself.
but bouncing around in the boot of a car for years sure could lead to it getting damaged..
Why on earth would you let it bounce around the boot of a car? The noise alone would be very annoying. Fasten it securely in a net or with your emergency pump, or simply keep it in the glove box, and it won't get damaged.
again its just not a risk id be willing to take myself.
I would consider that an irrational fear, but that's fine as we all have different irrational fears. I just think it's important for people to hear both sides of the story so they can make up their minds for themselves.
and that there is a good chance that it was an onboard fire which disabled the pilots
So the lipos caught fire, set the whole cargo area alight, rebooted, then disabled the ACARS system (but not the satellite transponders), disabled the pilots' oxygen masks, killed the pilots, and kept flying while on fire for 7 hours?
If you do not want to drive down to Target, you can get them from their ebay website:

Get more discount with cashreward.
This item is out of stock.
nope…
Out of stock on Ebay now.
Picked one up yesterday. There were 8 left at Target Toombul QLD, so it shouldn't be marked out-of-stock.
I took it apart to have a look. It's reasonably well-made inside (apart from that ugly stray solder blob on the rectifier at the top-right side of the rear pcb!). It's held together by two screws and two large pads of double-sided tape on both sides of the battery.
The battery is 11.1V 3,600mAh, so if you calculate it the usual way, it works out to be 10,800mAh at 3.7V which is slightly under their 11,000mAh rating.
The maximum pulse and continuous discharge rate is 40C, so it can put out 148A continuously.
It's made by Great Power who are reasonably well-established.
The battery manufacture date on mine is 19th Sept 2015.

Not out of stock per se. But I didnt know when the 30% off sale would be - hence timebombed it for the weekend on the post. Happy to change it if it is still avail for the discounted price of 48 bucks. :)
But thanks for the pics. Nice to know its well made for everyone's piece of mind.
It's in stock on their webpage. You can also still buy it in-store at that price, if it's in stock.
There's probably still a bunch more at Toombul. :)

awesome, this is exactly what i wanted to know
It's in stock on their webpage
it certainly wasnt yesterday because i went searching for it. said out of stock.
Unavailable online
Thanks for the great info & photos!
Still a couple at Strathpine
1 left in Civic store in Canberra. So the question now, how do you turn the LED light on? It was asked before,I thought I might ask again and hopefully someone has worked it out….
on my banggood one there is a button on the side that shows you battery level if you press it once, double click it quickly and it will turn it on/off
So the question now, how do you turn the LED light on?
Turn the jump starter on, then press and hold the battery check button for 3 seconds. Just like it says in the manual. ;)
Couldn't find it on the manual. Thank you…..
apparently there is stock at gawler SA. just did a C&C an hour or so ago and just got the confirmation sms.
Just did a discharge test at 1C, the capacity is reasonably accurate. Tested capacity is 3.357Ah at 3.6A discharge, end voltage 8.96V. I might run another test at 100W just for kicks!
Just checked some SA stock:
None in Reynella, Edwardstown, Unley or Marion.
Some had stock in the system but have sold out in the last 24 hours.
If you know any with stock in SA that's south of the city please let me know.
Cheers.
Around 10 units left @Buranda, QLD
Just bought two from Target Blacktown (10/5), plenty left.
Wires look 1/10th the diameter of a pair of jumper leads, must get hot?
usually the actual wire in jumper leads are thin with massive insulation around them.
ive used mine a heap and never had an issue.
Hi
Not sure if the power bank is faulty.
I jump started my old holden vt but then the power bank didnt turn on until i started to charge again.
The power supply read 75% charge so not sure why it didn't turn back on.
Next time i jump start, the red jumper cable desolder from the heat inside the red box.
Also jumper cables melting around metal teeth
Has anyone else had this problem??
did you charge it around 36 hours after took it out of the box?
Posted in the other thread but still 6 available at Toombul a few hours ago at $48.30
@Gaz1: I really wouldn't be too concerned. All those examples are of RC batteries that are subject to abuse and charged with external balance chargers of unknown quality which may have overcharged the batteries.
Your phone likely uses a lipo battery and it's perfectly safe as it's difficult for it to get damaged when it's within a device. The two double-sided pads that hold the battery in this jump starter are thick foam pads that provide some shock absorption, so it could even be safer than your phone.
What I'd be more worried about is cell degradation. Lithium rechargeable cells degrade more rapidly when stored at full charge at high temperatures.
