Samsung Wireless Charger Pad Slim (EP-P1100) Teardown Review
We have reviewed several wireless charging products including. They are all impressive products but however priced relatively high. To popularize wireless charging, Samsung released an entry-level wireless charger pad at the end of 2018, the EP-P1100, aiming at bringing 10W wireless charging to the masses.
It comes with a white plastic packaging.
Specifications on the back.
Package contents: wireless charger, user manual, warranty card, no power adapter or cable.
ADVANCED CHARGE lettering in the center.
Matte plastic material with a circular rubber pad.
Non-slip rubber pad on the bottom.
There is an LED indicator on the side which emits different colors to indicate the status.
USB-C port for power input.
A slim design of merely 11.9mm (0.47in) thickness.
Using the wireless charging aging tester, we read a "PFP" which means it passed the 5W and 10W test but fails the 7.5W test. So it supports normal 5W and Samsung 10W, but does not support Apple 7.5W wireless charging.
It starts charging instantly when we put the Samsung Galaxy S10+ on top, the screen shows the phone is getting fast wireless charging.
Removing the rubber pad on the bottom reveals 5 screws.
Remove the back cover. Inside is a circuit board with input pins and coil pads.
There are two chips on the circuit board, which are wireless charging IC and MCU.
Compared to a 1 Yuan RMB coin.
There are only a few small components on the back of the board.
The coil is soldered to the board through the opening on the board. The solder joint is round and full. The right side is the resonant capacitor, the MOS transistor, IDT IDTP9235 and ABOV MCU are used to apply for the voltage.
ABOV 8216 MCU
IDT P9235 wireless charging controller IC.
Four MOS tubes form an H-bridge, which performs wirelessly charging with a resonant capacitor drive coil.
Input overvoltage and overcurrent protection components to avoid damage to the charger.
