Nowadays many smartphone users suffer battery issues and slow charge issues due to bad charges you purchase or use on your device.
I have done a survey on one of the best chargers in the market and have understood their specs and charging speed and have compiled a comprehensive list of chargers.
*√Non-Verified* Fake Blackberry Charger Specs: Input: AC 100 – 240v (50/60Hz) Output: DC 5V (0.75A) Speed: Slow.
*√Non-Verified*Most Fake Chargers with Light Specs: Input: AC 100 – 240v (50/60Hz) Output: DC 5V (0.5A) Speed: Extremely Slow.
*√Verified* New Age Energizer Specs: Input: AC 100 – 240v (50/60Hz) 0.15A Output: DC 5V (1A) Speed: Very Fast.
*√Verified* Standard Gionee 1A Charger Specs: Input: AC 90 – 300v (50/60Hz) 0.15A Output: DC 5V (1A) Speed: Very Fast.
*√Verified* UK Based Woo Charger Specs: Input: AC 100 – 240v (50/60Hz) 0.2A Output: DC 5V (1.5A) Speed: Extremely Fast.
*√Verified* Original Blackberry Charger Without USB Specs: Input: AC 100 – 240v (50/60Hz) Output: DC 5V (2.0A) Speed: Excellently Fast.
So purchase only chargers with the verified specs every original charger has the specs written clearly on it then get an original USB cord, cause sometimes slow charge is caused by bad USB cords.
