Power Bank Buying Guide – 20000mAh vs 10000mAh

Light cut? Traveling Kota to Jaipur? Coaching 10 hours? Power bank is must. But 70% people buy wrong capacity.

5 Mistakes to Avoid:
Mistake 1: Buying 10000mAh for daily heavy use
10000mAh = 1.5 charge only. If you use phone 8+ hrs, it finishes in 1 day. 20000mAh = 4-5 charges, lasts 2-3 days. For students, choose 20000mAh.

Mistake 2: Ignoring LED Display
Without display, you don’t know remaining charge. Always buy with digital % display like our RJ20 Power Bank 20000mAh — shows exact 1-100%.

Mistake 3: Cheap Cable = Slow Charge
Original power bank + cheap cable = slow. Use 20W Type-C cable. We bundle fast cable at RJ20.

Mistake 4: No Overcharge Protection
Cheap ₹600 power banks blast battery. RJ20 power banks have 6-layer protection — overcharge, short circuit, temp control. Safe for hostel use.

Mistake 5: No Bill = No Warranty
Local shops sell without bill. At RJ20.in Bhonhra Circle, you get GST bill + 6 month replacement warranty.
