How to Keep Your Phone Charged During Long Power Cuts
Quick answer

A phone battery is typically around 4,000 to 5,000 mAh, so a 20,000 mAh power bank gives roughly three to four charges in practice. Charge the power bank when power is on, keep a car charger or solar charger as a second source, and turn on battery saver. Keep the router on a UPS if you rely on Wi-Fi.
