There is a universal charger that will not damage the battery. I just developed it this year and applied for a patent. The patented product of this invention (Patent No. 200910105433.2) is a car charger, USB charger, and travel charger. It is a new universal charger that integrates an ordinary rechargeable battery charger and a lithium battery charger. It can adapt to batteries of various shapes, and has the ability to automatically identify various battery charging voltages, automatically control charging current, and automatically identify the positive and negative poles of the battery. It is a new product with polarity and other functions, fast charging and easy to use.
This product is designed and developed in accordance with 3C, CE, and UL standards, and adopts advanced and mature charging control technology: including AC/DC control, DC/DC control, battery voltage identification, battery polarity identification and verification. Over-discharged battery forced start identification and so on. The main performance is as follows:
Input:
AC input: 100V—240V 60HZ/50HZ 150MA
DC (USB) input: 5V—24V 2A
Output:
USB output: 5V 1A
OUT1: 1.5V/4.2V/8.4V 1A/0.65A/0.5A (battery nominal voltage 1.2V/ 3.6V/7.2V)
OUT2: 4.2V/8.4V 0.65A/0.5A
The product will be available in mid-March
