New Xiaomi mobile power supply 2, 18w two-way fast charging, but unfortunately the charging port is not type-c, so we will force it to participate in our C port unification cause
Those who are too lazy to read pictures and texts can go to my video channel for viewing
Power bank uses a single-sided security blade to pry open
from the edge gap and pry it flat, so you can remove
Once you reach a little, the one behind is very easy
The same is true for you. . . (Give a point here)
Unscrew the two screws at the bottom
and use a random piece to pry out the black piece
Use your finger to push out the inner core. . . Repeating words, disgusting
circuit board two screws removed
pry stick and pry it out
Because the battery cell and the board are spot-welded, I don’t want to remove it and then solder , so I operated on the live
lighter method to remove the micro mother seat, awesome
Pay attention to the angle and heating time, pull the tweezers out slightly, don't burn the surrounding components, after all, the flame temperature claimed by the seller can reach 1300℃
The remaining plastic is soldered with a soldering iron
Because the mother seat of the C port is relatively large, in order to make room for it, the original positive and negative electrodes are soldered in another place, and the solder joints are also large, killing two birds with one stone
micro The 5 solder joints are the positive electrode on the left, and they are connected to a circular electric shock
micro The 5 solder joints have the same negative electrode on the rightmost side and the row below. Choose a lot of
Let’s first we solder the fly wire to the c-port mother seat. The solder joints are from left to right, positive electrode, cc1, cc2, positive electrode, negative electrode
After welding, check
After testing correctly, put ab glue fix
and solder to the board
is fixed with double-sided foam glue and has the effect of insulating
Replace the battery rack , check the position of the charging port, prepare to polish
a little bit, slowly file
file a few times to compare once, slow work and work hard
When the size is appropriate, prepare the final fixed
You can guess the effect of this step. Spray some lubricant on paper
smear on the c port data line
After inserting into the c port mother seat, fix the mother seat with hot melt glue
The angle will be a bit biased. Stand it up and use its own weight to correct
Hot melt glue test again after cooling , confirm that you can charge
Finally, after polishing the surface cover, the shape of the c-hole of the surface cover is basically completed.
Still a little anxious, it is not very perfect
There is still a gap
Overall, it is OK, but there is no USB voltage tester on your hand, and you don’t know how much the charging current is. There is also no cc wire, so you can’t use C To C cable charging depends on personal needs. I can't use the cc cable, so it doesn't matter.
Finally, let's add the unified plan for C port
