power bank par likhi mAh ki sankhya dekhkar hi mat khareedie. usmen se kuchh hissa charj karte samay bekar chala jata hai, isliye asli charj likhe aankade se kam milta hai.
samjhane ki baatein:
1. 10,000 mAh ka power bank aam taur par phone ko utni baar charj nahin kar pata jitna aankade se lagta hai. asli sankhya phone ki battery par nirbhar hai.
2. aautput watt dekhen. aapka phone tez charjing manta hai, to power bank bhi usi speed ka hona chahie.
3. port: USB-C aur USB-A donon hon to suvidha rahti hai.
4. suraksha: ovraheeting, short-sarkit se bachav aur bharosemand brand dekhen. BIS jaisi manzoori ka nishan dekhna achha rahta hai.
5. vazan: badi kshamta ka power bank bhari hota hai. roz sath rakhna ho to chhota len.
6. havai yatra: power bank aam taur par kebin baig mein hi rakhna hota hai. eyralain ke niyam pehle dekh len.
