Mr. Clean Magic Eraser is a household cleaning product that is sold in various stores, including Home Depot. It is known for its ability to effectively remove tough stains and grime from different surfaces. The product is available in the form of a sponge-like eraser that can be used for a wide range of cleaning tasks. The Magic Eraser is made from a unique material called melamine foam, which is highly effective in tackling stubborn stains and marks. When moistened with water, the eraser creates a slight abrasion that helps to lift and remove dirt and grime without the need for harsh chemicals.

Teardown
Pry open the charger case and pull out the internal PCB board.
A large amount of glue was used to fix and dissipate heat between the components on the front side of the PCB. The transformer marked part number of the core type and the date of manufacture.
The input end was distributed with a delay fuse, an NTC surge suppression resistor, a common mode inductor, and three primary filter electrolytic capacitors.
An electrolytic capacitor from BERYL at the input, all three capacitors share the same specification of 400V 15μF, a total of 45μF.
The delay fuse, 2A 250V.
3D-7 NTC surge suppression resistor.
The Y capacitor which belongs to the CD series MLCC by Matsuda Electronics.
PC817 optocoupler for output voltage feedback.
The output USB-C port is fixed to a small PCB daughterboard. Due to the end of the small PCB daughterboard is very close to the primary side, it is wrapped with tape for insulation. Nearby the daughterboard is an optocoupler with glue insulation and there are two solid capacitors for output filtering.
The two output filter capacitors are also from BERYL, the specifications are 560μF 25V.
The blue Y capacitor is glue to the transformer.
Inside the PCB board, there are sufficient spacing reserved between the primary and secondary side.

The PWM controller LD5763GS from Leadtrend. The LD5763CGSU is a green mode PWM IC built-in with brown-in/out functions in an SOP-8 package. It minimizes the component counts, circuit space, and reduces the overall material cost for the power applications.
The LD5763CGSU features HV start, green-mode power-saving operation, and internal slope compensation, soft-start functions to minimize the power loss and enhance the system performance.
With complete protection including OPP (Over Power Protection), OVP (Over Voltage Protection), fast OSCP (Output Short Circuit Protection) and brown-in/out protection, LD5763CGSU prevents the circuit from being damaged under abnormal conditions.
Furthermore, the LD5763CGSU features frequency swapping and soft driving function to reduce the noise and improve EMI.

Skysilicon synchronous rectification driver and LD8526 MOSFET on the secondary side. Leadtrend LD8526 is a secondary side synchronous rectification (SR) driver IC designed for PD. It was suited for flyback low side and high side synchronous rectification in CCM, DCM and QR mode. LD8526 can generate its own supply voltage through low output voltage or high side rectification applications to charge the battery, suited for PD application, which output voltage range from 3V to 20V. In light load condition, LD8526 will enter green mode to reduce operation current by stopping the SR MOSFET driving function.

Reviews for "The Quick and Easy Way to Clean Your Home: Mr. Clean Magic Eraser Home Depot Edition"
1. Sarah - 2/5 - I was really disappointed with the Mr Clean Magic Eraser from Home Depot. I had heard so many good things about it, but it did not live up to the hype for me. I tried using it to clean some scuff marks off my walls, and it barely made a difference. I had to scrub so hard just to get a little bit of the mark to fade. It was also really flimsy and fell apart after just a few uses. Overall, I think there are much better cleaning products out there that are more effective and durable.
2. John - 1/5 - I bought the Mr Clean Magic Eraser from Home Depot thinking it would be a game-changer for my cleaning routine, but I was sorely disappointed. It did not work well on any surface I tried it on. I used it on my kitchen countertops and it barely made a dent in the stains. I also tried it on my bathtub and it barely removed any grime. I ended up having to use a different cleaner to get the job done. I would not waste my money on this product again.
3. Emily - 2/5 - I was really excited to try the Mr Clean Magic Eraser from Home Depot after hearing so many positive reviews, but unfortunately, it did not work well for me. I used it to clean some scuff marks on my laminate flooring, and it left behind streaks and residue. I had to go over the area multiple times with a different cleaner to get rid of the marks and the residue. It was also not very durable and started falling apart after just a few uses. Overall, I was disappointed with this product and would not recommend it.
