Genuine vs. Fake Power Bank: How to Tell Before You Buy Online
Because power banks look similar from the outside regardless of what's inside, capacity and safety claims are easy to fake in online listings. A few checks before buying can save you from a battery that underperforms or degrades fast.
Check the capacity math
No power bank delivers its full rated capacity to your phone — 15–25% is lost to voltage conversion, and wireless charging loses more. If a listing implies a 10000mAh bank will charge your phone 4+ times, that's a red flag; realistically it's closer to 2–2.5 charges for most phones.
Check the weight-to-capacity ratio
Lithium-polymer cells have a fairly predictable weight for their real capacity. A power bank claiming 20000mAh that feels unusually light for its size is worth double-checking — it may not contain what the label says.
Look for specific safety certifications, not just claims
“Safe and reliable” in a product description means nothing on its own. Look for a BIS certification mark (mandatory for electronics sold in India) and specific protection features listed — overcharge, short-circuit, over-voltage — rather than vague marketing language.
Check seller and brand accountability
- Is there a real brand name, or a generic/rotating listing title?
- Is there a working warranty and support contact?
- Do reviews mention the product by name and specifics, or do they read generically (a sign of review manipulation)?
Bottom line
A genuine power bank's specs should hold up to basic scrutiny — realistic capacity claims, named safety features, and a brand you can actually contact if something goes wrong.
