Universal charger makeshift

"crack!',my classmate just broke my universal charger.He better replace it or he'll have to find a place for his body to rest x)).While he has not replaced it yet (or is he going to?) i need to find a way to charge my other batteries.Now i got 3 choices,its either i borrow from other people, borrow from my brother or do something with the charger.

After dinner,i turned my room inside out to gather resources,what i got was,a pair of wires,a SIM card and a scotch tape.I examined the charger and found out that if i unscrew the negative and positive receivers(or what ever it is) i can do a wonderful thing with it x).
So here's what i did:

I attached the wires on the base of the positive and negative receivers and connect it to the other part of the receivers which i unmounted and placed it under the SIM card,the scotch tape did all its wonders to keep it there.Then i bent the unmounted receivers (which are now attached to the SIM card) to about 40 degrees,just the right angled to hit the batteries,then i tested it.And it actually works!!!(why shouldn't it? its just basic).

looks crude(looks like an improvised explosive x]) but the important thing is that i works.I think i can get used to this universal charger makeshift while the replacement hasn't been granted yet.
