Power banks work by using sophisticated electronics to manage taking in charge from a charger, storing it in a battery and then charging other devices. Power banks are not just a simple battery: they use sophisticated electronics circuitry to manage being charged, and then charging other devices.
On average, power banks last 4 to 5 years and can hold a charge for 4-6 months without losing much power. For example, a 5000mAh portable charger that's powered up once every two days, it will need 1,000 days to reach the 500 charge-discharge cycles and drop to 80% capacity. If the description of a portable power pack doesn't specifically mention your device, compare its specs to those of your existing charger. An iPhone and most Android smartphones need at least one amp (five watts), for example, while an iPad and other tablets expect 2.4 amps (12 watts). It's important to get this right.A small power bank will store somewhere between 2500 and 3000 mAh, meaning it has enough juice to give most smartphones one full charge. Be aware that this isn't always true these days, since many phones are coming with larger batteries, but this size should give you somewhere between 60% and a 100% charge.
