RE: 有無最強多位PD充電器介紹?

就算係100W嘅 "大牛",不同廠家設計,輸出條件/限制,亦各有不同。

例如V牌呢款4 ports貼牌貨,兩個C ports同時插devices時,每個port PDO係60W max,USB-A1(18W max) 或/及USB-A2(18W max)再插入device時,對C1 C2嘅PDO冇影响,但若各ports都扯盡,例如有人會誤以為可以 60 + 60 + 18 + 18 = 156W,隻牛就有機會overload,自行cut斷輸出或/及reset。

而X牌呢款5 ports貼牌貨就比較 "智能",兩個C ports同時插devices時,C1係60W max,C2係30W,3個USB-A port再插入device時,對C1及C2嘅PDO會有影响,可以睇返#71樓嘅介紹。

以上呢兩款100W貼牌牛,各有優缺點,論裏面用料做工,5 ports係稍好,而且有 "智能" 調整(限制)各ports功率,安全性理論上亦較好,但因為每次插/拔device時,佢都有機會進行 "智能分配",各輸出port會暫斷一下電,再重新輸出,部份正在以PD快充協議(C port)充電嘅device,未必可重新 "咬" 返個對應嘅PDO,導至未能充電,有可能要重新拔插一次,但隻火牛又會再次自動 "智能分配" 一次,有時比較困擾。

而4 ports嗰款使用上相對 "比較" 方便,但安全性 "理論上" 相對稍差。

MOMAX未收到,未知。

ELECJET及DIVI係可以同時20V,但要留意呢類65W 3ports (或2 ports)設計,雖然係兩組 ...

    how about baseus pls?  

thanks for your expertise in this GAN PD charger.  

I have asked CS of momax, CS says 18 w is either 9 or 12 volt.  no thank you if that's the case.

found it.  baseus also sw3510.  ie, same as momax.  no need to pay for momax then.  

shame elecjet is bit relatively pricey.

Sales及CS不嬲都係斷估。。。
問佢哋,不如自己睇spec或search review。

if momax can c1 + c2 both 20v, would buy.   but still searching can't find the answer yet.

found It, indeed momax c2 only 9 or 12 v when c1 and c2 both used.  

no thank you.
