Asaan usool: 10000mAh wala bank aam phone ko taqreeban derh se do dafa, aur 20000mAh wala teen se chaar dafa charge kar sakta hai. Apni zaroorat ke mutabiq chunein, baghair wajah bara bank le kar wazan na uthayein.
2. Output Speed Aur Watt
Sirf capacity nahi, speed bhi dekhein. Agar power bank ka output sirf 10W hai to phone bohat slow charge hoga. Fast charging ke liye kam az kam 18W se 25W output aur aapke phone se match karta standard, jaise USB PD, lazmi hai. Box par output ki tafseel wazeh likhi hoti hai, usay parhna na bhoolein.

4. Ports Ki Tadaad Aur Type
Dekhein ke bank mein USB-C aur USB-A mein se kaun se ports hain, aur kitne hain. Agar aap aksar do devices charge karte hain to do ports wala model behtar hai. Yaad rakhein, do devices aik saath lagane se speed aksar dono mein taqseem ho jati hai.
5. Built-in Cable: Sahulat Ya Extra Kharcha
Kuch power banks mein cable sath bani hui aati hai, jo safar mein bohat kaam aati hai. Lekin built-in cable kharab ho jaye to pura bank bekar mehsoos hota hai. Agar aap ehtiyaat se istemaal karne wale hain to built-in cable sahulat hai, warna alag achhi cable ke saath simple model zyada dair chalega.
6. Safety Protections
Power bank battery wala device hai, yahan samjhota bilkul na karein. Over-charge protection, short-circuit protection aur temperature control jaisi features box par likhi honi chahiyein. Ghair mashhoor aur bohat saste banks mein ye systems aksar maujood nahi hote.
7. Wazan Aur Size
20000mAh wala bank aam tor par bhari hota hai. Roz jeb ya chhote bag mein rakhna hai to 10000mAh ka halka model zyada practical hai. Bara bank sirf tab lein jab waqai lambe safar ya zyada devices ki zaroorat ho.
8. Indicator Aur Display
LED dots se andaza hota hai ke kitni battery bachi hai, lekin percentage display wala model zyada wazeh maloomat deta hai. Ye chhoti si cheez roz ke istemaal mein bara farq daalti hai.
