What the specifications mean

• Capacity — 6500mAh

This is the total amount of energy the powerbank can store.

Higher mAh = more charging power.

6500mAh is enough for 1–2 full charges of most modern smartphones.

Because energy is never 100% efficient (typically around 70–80% efficiency), the usable capacity is closer to:

➡️ ~4500–5200mAh of real charging power

Input — 5V / 2A

This is how fast the powerbank itself recharges.

At 2 amps, the powerbank charges reasonably quickly.

Charging time for the powerbank:
6500mAh ÷ 2000mA = ~3.5 hours
(Usually 3.5–4 hours in real usage)

Output — 5V / 2A

This is how fast the powerbank can charge your phone.

5V = Standard USB charging voltage

2A = Enough for normal-speed charging for most phones

It does not support fast-charging systems like QC or PD, but provides solid everyday charging.
