A good power bank for your smart phone shouldn't be too big, but it should have sufficient capacity. A 10,000mAh power bank allows you to charge your smart phone about 2 times and it'll usually still fit in your pocket. A larger, 20,000mAh model is useful for a camping trip during the weekend for two, but it probably won't fit in your pocket anymore. Many smart phones support fast charging; check if your device requires Quick Charge (Android) or Power Delivery (Apple and some Android devices).
