Charger question

[DLL9MM]

I am currently using a trustfire tr-001 to charge my AW 2900 Mah and Ultrafire 2600 batteries.
I wanted a backup charger, so I order one from China for $3/shipped. Got it today. Here are the specs....

Input: 100-240V
50-60Hz
Output 3.7V/300mA


My Trustfire TR001:
Input 100-240V
50-60Hz
Output 4.2V 500ma

Should I order another charger or will this charge my batteries. This is a backup charger.

That charger should be ok. Not knowing if it has overcharge protection don't use unprotected cells in it but your AW and Fire Protected cells should be ok.

3.7 is just the nominal charge rating, Your batteries will actually charge closer to 4.2 before the protection kicks in to keep them from going higher and the 300ma is the rate in which it charges. It'll take longer than your TR001.

Awesome. Thanks for the info!
