Hey everyone,
About 12 days ago, I set out on a mission to find out which charger among my collection was giving my iPhone 15 Pro Max the most power. What I didn't realize at the time was that measuring the power the brick draws from the wall is just one piece of the puzzle ( thank you u/janxb) . The real revelation is in how much power is delivered to the phone itself. Today, after finally getting my hands on a USB C multifunction tester, I'm ready to share the results with you.
I created some rankings for both power delivered to phone and brick efficiency.
You may remember this picture from the initial test, these are the bricks that i tested and how much they draw from the wall.
Bricks ranked by power delivered to phone:
| 1) Ugreen CD224 65W charger | 25.737 W |
|---|---|
| 2) Apple Brick 96W (2019) | 25.031W |
| 3) Apple Brick M2 MAX | 24.514 W |
| 4) Samsung EP-TA800 | 23.163 W |
| 5) Apple 20W charger | 19.09 W |
| 6) Apple 18W charger | 17.113 W |
Bricks ranked by power efficiency:
| 1) Apple Brick 96W (2019) | 89 % |
|---|---|
| 2) Apple 18W charger | 88.2 % |
| 3) Samsung EP-TA800 | 86.1 % |
| 4) Apple 20W charger | 81.9 % |
| 5) Ugreen CD224 65W charger | 81.8 % |
| 6) Apple Brick M2 MAX | 79.5 % |
The individual charger measuring are here:
Ugreen CD224 65W charger
wall draw - 31.4-31.7 W
delivered to phone - 25.686-25.737 W
Charger efficiency - 81.8 %
Wattage lost - 5.7W
2) Apple Brick 96W (2019)
wall draw - 28.1 W
delivered to phone - 25.031W
Charger efficiency - 89 %
Wattage lost - 3W
3) Apple Brick M2 MAX

5) Apple 20W charger
wall draw - 23.3 W
delivered to phone - 19.09 W
Charger efficiency - 81.9 %
Wattage lost - 4.2W
6) Apple 18W charger
wall draw - 19.4 W
delivered to phone - 17.113 W
Charger efficiency - 88.2 %
Wattage lost - 2.28 W
In conclusion, these results might change the way you think about charger performance. Not only does it matter how much power a charger draws, but also how efficiently it delivers that power to your device. It's a win-win situation if you find a charger that delivers a lot of power with high efficiency.
Feel free to ask if you have any questions or need more details on this charger efficiency test. Thanks for reading!
For me i'll stick charging with the Ugreen charger since all i care at some days is getting my phone charged as quickly as possible.
