Samsung S22 Ultra超快速充電條件研究與相容的行動電源/充電頭/車充

S22 Ultra買來之後一直都用筆電的Type-C 65W充電器來充,
但是越想越不對勁,這充電速度…真的有45W嗎?
買了一個USB Type-C電流電壓錶來看之後才發現原來只有15W。

看了一下原廠45W充電器EP-TA845的規格是
- Charger: USB PD3.0 PPS. PDO : 3A(9V, 15V), 2.25A(20V) / PPS : 4.05A(3.3-11.0V) or 2.8A(3.3-16.0V) or 2.1A(3.3-21.0V)
- Cable: USB Type-C to Type-C e-mark 5A
其實以這個規格的充電器來說並不貴。(訂價$1590,2022/5已經掉價到$1200左右)

但!依照各大評測,25W和45W的充電速度根本沒差幾分鐘,所以弄個30W以下的相容方案就好了。
經過一番Google決定採用以下方案。
- 充電頭:POLYWELL PD 30W雙孔Type-C
- 行動電源:ZMI QB818
- 車充:ONPRO GT-PD30MINI 30W


2022/6/19 EDIT:
POLYWELL PD 30W雙孔Type-C。已購入測試可觸發30W充電。
ONPRO GT-PD30MINI 30W。已購入測試可觸發30W充電。
三星雙向閃充行動電源 EB-P3300。已購入測試可觸發25W充電。

EB-P3300剛好在網路上找到贈品轉售的,用不到五折價購入,真香。

Samsung Galaxy S22+ and S22 Ultra's 45W charging doesn't really make a difference
> What does this mean? Well, Samsung’s 45W charging rate claim is outright misleading when even paired with the original Samsung charger it does not offer any real tangible benefits in terms of charging times over the 25W solution.

Tested: The Galaxy S22 Ultra’s 45W charging is barely faster than 25W
> we see that charging with the 45W plug hits all the battery milestones faster than when using a 25W charger, but the margins are very slim. We’re talking a 3- to 4-minute difference to hit 50%

[問題] 能讓S22U開超快2.0的行動電源
> → OnePlusDash: 簡言之,三星的45W超快速充電2.0呢,不管是充頭
> → OnePlusDash: 還是尿袋,充電協議裡都要有PPS含有11V/4A的檔次
> → OnePlusDash: 然後線材要有e-mark認證,4A以上的線
> → OnePlusDash: 雖然我覺得糾結這個沒意義..因為跟25W速度差不多
> → OnePlusDash: 買能到25W的組合就好
