TP405 5V Mini USB 1A Lithium Battery Charging Board Charger Module (FS00728)

Specifications

  - Charge module- linear charging

  - Current- 1A adjustable

  - Charge precision- 1.5%

  - Input voltage- 4.5V-5.5V

  - Full charge voltage- 4.2V

  - Led indicator- red is charging blue is full charged

  - Input interface- mini USB

  - Work temperature- -10℃ to +85℃

  - Inversed polarity- NO

  - Size- small to 25x19x10mm

Note

  - Ampere meter can only be connected to 5v input end of the module.

  - It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAH, current of 400 is enough.

  - The connection wire should not be too thick.

  - Make sure the connect point is good

  - If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-substract the charging current to avoid burn damage to chip.
