Input interface: Micro USB
Features: With a Micro USB port, can be charging rechargeable lithium battery directly as a phone charger. Retains voltage input wiring pads, convenient for DIY. This module can charge for single-cell lithium battery or multi-section parallelled lithium batteries, can be powered by USB ports. With LED indicators, easily read the charging status.
Specifications: Input Voltage: 5V Full charging voltage: 4.2V Max output current: 1A Power Indicator: Red for charging, Green for fully charged. Input interface: Micro USB Charging Precision: 1.5% Operating Temperature: -10 ° C ~ +85 ° C Item Size: Approx. 25 x 19mm. It can be used for voltage 3.6, 3.7V, etc. 18650, polymer and other lithium battery charge and discharge protection.
Current Regulation: RPROG(k) - IBAT(mA) 30k - 50mA 20k - 70mA 10k - 130mA 5k - 250mA 4k - 300mA 3k - 400mA 2k - 580mA 1.66k - 690mA 1.5k - 780mA 1.33k - 900mA 1.2k - 1000mA
Cautions: 1. Please make sure the battery is well connected. 2. Please do not connect the output reversely, otherwise it may burn the chip. 3. The connection wire should not be too thin or too long. 4. Current meter can only be connected with the module in series with 5V input. 5. Charging current is better to be 37% of the battery capacity. If you want to charge a battery of 1000mAh, 400mAh current will be enough. 6. High voltage protection, the current will be lower than 1000mAh when the voltage is higher than 5V. It subtracts the charging current automatically to avoid burn damage to chip.
Package Includes: 10 x TP4056 with Battery Protection LIPO Charger Module Board Micro USB
They charge around 1 amp and they just seem to work. I was having some poor results with other chargers either taking eons to charge a single 18650 cell or not charging them all the way. Life has been better since I got these and made a few little 18650 chargers. The rest will be saved for various projects where onboard charging is needed.
These are simple chargers for generic Li-Po batteries. The current needs to be low or the device overheats. No short circuit protection. Be careful. The top off voltage is close but not perfect and since it is at 4.2 V can tend to either over or under charge depending on condition. That said. Charge at low current, low to mid temperature, keep away from heat. A diode or mosfet protection between terminals could improve the design.
Used one on a tablet that the USB broke on bypassing the electronic and hooked straight the the battery and now I can charge the thing
I bought these to attempt to charge a LiPo pack in one of my projects, and despite little documentation, I was able to charge my pack, and decided to begin stocking these in my parts inventory.
Great value!

Product is as advertised
Charge protection only. Does not do over discharge protection at all.
All of them work great. I just need to stop putting in the cells backwards and frying them.
They’re cheap, and they work.
Inexpensive charger for Li-ion or LiPo batteries. I am using one with a solar cell and a boost converter to power a device outdoors.
Yeah, shipped with SMD capacitor bouncing around in package. Not happy at all, need these for STEM project. How about sending me new ones. Seriously, you get what you pay for.
