NO, not only in America both companies are American therefore would not break copyright laws, the energizer bunny is a trademark, the problem lies with lowlife foreign companies who steal american intellectual properties. counterfeit batteries are a well known problem in lesser countries.

I made a guide inspired by the circuitry found on the web and I optimized.

Anyone else notice that the Duracell box had the Energizer Bunny on it?

i did. WTF

Only in America does Energizer have the bunny as a trademark. Elsewhere, duracell also has bunnies.

What is the polarity on phones using a Micro mini USB connection like the Motorola phones and the LG phones?

where do you connect the resistor in the positive flow or the negative?

Doesn't really matter here.

bit of a noob question: do i need a regulator/resistor at all?
can't i just use a 6v battery combo to charge a 5.2v device?
or will that be a very bad idea?
suggestiond please.

I would just do the same, except with a 6-volt spring-terminal lantern battery

I have to say that it is clever but not very useful. If in order to create this charger you require a cable that plugs into the phone it is most likely that that original cable could be used to charge it either through a computers usb or the mains anyway. I guess it is useful to take with you on a trip.

If there was a way to charge a phone BATTERY so you don't need a cable to plug into it then it would be more useful.

I think you should just make it 6 batteries and hook it up to a 5v reg.

Dec 12, 2009. 9:27 AMivaneduardo747 says:

Thats much better than putting a 2 ohm resistor, specially because if the cellphone does not use much current.

Dec 12, 2009. 10:18 AMBOOM5601 says:

The reg is supposed to use 5 ma anyway.

for how much times will it work??

Aug 19, 2009. 7:46 AM555mst555 says:

this one is not very good....coz once ur batteries go to below 5v u cant charge anymore....u should use a 9V and hook it up to a 5V regulator...i made one...it worked well on my psp

untill the batteries die.. :)

does this work for every cell phone?

Jan 28, 2009. 6:34 AMjedi pen-gui-n says:

it depends on the plug you use . it should

Jul 15, 2008. 11:05 AMblue200316 says:

how will i check the phone's polarity, how will i find out which wire is positive and which is negative of the charger plug? i have many old nokia chargers and use a nokia phone. please tell me, i really liked this and i want to make it my self.

Aug 2, 2008. 12:20 PMcomputer_gui says:

the center of the plug is genraly positive some of the older ones are colour coded so red is (+) black is (-)

thanx for the info.now i will make this charger. :)
