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
