A55 is rated upto 25W wired charging.
You can use 15W Samsung charger also. no problem in using that.. that's the answer. But in next comment I'll explain everything about charging and chargers.

Ye kis brand ka charger hai ?

Wese charge to 15W tk theek krega, lekin better hai aap Samsung ka original charger buy kr lein. 25W wala.
Wo ziada batter rhega.

G. Is se charge ho jaega. Lekin better yehi hai aap 25W ka charger buy kr lein

Uski reason ye hai 15W ho ha 25W, heating almost same h dono ki (I have checked on both)
25W 1 ghnte mei mobile charge kr dega. To better km time heat hogi.
15W 2 hrs lega. To 2 ghnte battery heat hoti rhegi.

Jitni battery heat hoti hai utni uski life km ho jaati hai.

Complete Explanation: Kisi bhi mobile ya charging device pr rated capacity se ziada wattage ka charger lga skte hn. Chahe aap 15W supported device pr 1000W ka charger lgaein. Koi issue nhi hoga. Charger ka kaam sirf rated voltage pr power provid krna hai. Mobile 15W ka hoga to 15 W hi draw kr skega charger se. Us se ziada nhi.
Jese utility companies hme connection deti hn, hmare load (device) pr depend krta hai hm kitni power draw krte hn.

Mobiles mei sirf 1 baat ki ehtiyat zaroori hoti hai. Charging protocol same ho.
Charging protocol se mtlb hai rated voltage.
Kuch companies alag alag charging protocol use krti hn.
For example Samsung ye protocol use krta hai
--15W = 5V x 3A
--25W = 9V x 2.77A
-- 45W = 15V x 3A.
Aap Samsung ka mobile jb bhi new charger se charge krne lgein to bs Voltage rating dekh lein k yehi ho. Baqi wattage chahe 100W ho. Koi msla nhi hota.

Kuch brands jo alag protocol use krte hn, unki rating aese hoti hai
For example OPPO
--15W = 5V x 3A (same as Samsung)
--33W = 11V x 3A
--36W = 12V x 3A

Iska mtlb hai agar hm oppo ka 33W ka charger Samsung k 25W supported mobile pr lgaeinge to Mobile 25W pr charger nhi hoga. Sirf 15 Watt pr hi charge hoga.. Q.K Samsung 5V accept krta hai. 11V nhi.

Is liye sirf jin brands ki charging technology change hai wahan pr ushi brand ka charger use krna chahiye. Wattage chahe 100W wala ho us se msla nhi hota
