The fact that it can take a variable voltage input (9-15V), plus the fact that the SUPPLIED power supply is exactly that - a power supply, not a regulated charger, makes me believe that the regulation circuitry is built into the battery pack.
The fact that it's able to accept a variable input voltage means the input is regulated, this has absolutely nothing what-so-ever to do with it being able to cut-off the charge current at the the right voltage or it having over charge protection.
You also have absolutely no idea if the main socket is a power supply or a charger just from looking at a quick picture.
Thats right, that battery pack comes with a power pack, all the regulation ect is built in the battery pack.
Just like a mobile phone and all other things with plug in power supplies.
Again absolute guess work.
If this is indeed a liPo based battery and you are wrong, you are without a shadow of a doubt putting the op and everyone in the car and driving near him in at an extremely high risk.
If his cells are Lithium based and they do go into a overcharged state, if the op is driving the car will be filled with noxious, toxic and acidic smoke thick enough to make breathing extremely difficult and certainly thick enough to make driving impossible.
That's the best case scenario as well.
If the pack ignites it will flare up with the power of a catherine wheel burning anything within 1/2 meter.
If, maybes and possibilities are simply not enough here.
Unless you are 100% sure you have a responsibility to the op and anyone else that reads this to be 100% right.
Judging an electrical device by a picture of it's external packaging is absolutely ridiculous, pointless and totally unacceptable.
It may seem to some that i'm being a bit over dramatic here, thing is i have been using lithium based cells for around 10 years now, i personally witnessed them burn, RC planes, helicopters and cars to a chard wreck, i've even witnessed a members Toyota burn to a crisp from bad charging practices.
Imagine this happening in the car as the op is driving with his entire family in the car

That LiPo flared up from overcharging exactly the same thing i'm banging on about.
As i say unless you are absolutely 100% sure that this product is NOT running lithium cells and unless your 100% certain the charging circuit is built into the device you are bang out of order and without any over dramatics you are putting peoples lives at risk.
