It uses a linear regulator. You can easily change the sense resistor to set current . The strategies programmed inside are useful fo revive dead batteries. and to protect in case of problem... at the moment no one. the linear regulator can whithstand more than 5V. (if im not wrong, 14). Of course power dissipable is limited by package and PCB, so current ... Read more
Board is very small, it makes it easy to hack it into any devices. Charge the battery as intended. Pads available to connect battery and power supply makes it easy to hack wires to it. One of the boards has one side uncut (a board that was in the outer section of the pcb panel) its not a big problem, that makes the pcb 2 mm larger... I hacked this little ... Read more
This is a great product and works fine. The quality is great and at this price, it's a steal. One can't really ask for much more. Good job DX for offering this quality, this cheap. One of the pros is definitely the shipping times. I received it in just 15 days in Greece which is more than excellent considering that i chose the simplest shipping method ... Read more
its very small, good to use. Output 1Ah thats very good for cheap charger, also this charger doing "smart charge" of battery at end of charging output is 20-100mA, it gives longer life for battery.
I like it. Doesnt have a fuse. I destroyed charger when ? mixed up + and -.
Next is output 5V, but need 4.2V or maybe i was unlucky with 1 charger ... Read more
Soldering quality is decent and the board well cleaned up (no flux residues).
The board is very small and can easily be hidden away in your project. Although the board is small the soldering pads are large ans easy to solder to. This board is the cheapest I found with the TP4056 chip on it. The pin for battery temperature shutdown (see datasheet for ... Read more
Chip code visible on my boards, TP4056...Thanks Ralph! I have not yet connected one, but they seem pretty good from a build standpoint. Should be quite useful!
Use with an overload protected cell, and all should be well. Fuse your supply line, USB will limit itself.
Safely Packed for ESD protection. Linear power consumption is good and quiet, not quite ... Read more
Very simple and easy to use! Only install the battery + and - points. I loved because it is exatly i need. I recommend for all users, experts or not. It is very small product. It is perfect, the best circuit I bought here informação the DealExtreme. Only lights is confuse, red is finished charger. I recommend! Very simple and easy to use! ... Read more
