Frequently Asked Questions
How many extra mAh do I need to get through a full day on campus?
Estimate based on your camera and phone use: a 12400mAh power bank will typically recharge small mirrorless camera batteries multiple times and top up a phone once or twice. If you shoot heavily (video, long timelapses), choose higher capacity or carry 2–3 spare camera batteries sized to your model.
Can a USB‑C PD power bank charge my mirrorless camera directly?
Many modern mirrorless cameras support USB‑C power delivery for charging or running the camera. Check your camera’s manual for USB-C power support and required wattage; a 20–45W PD bank will work for most phones and many mirrorless bodies, while older cameras still need dedicated battery chargers or adapters.
Is it better to carry spare branded camera batteries or a multi-slot charger with a power bank?
Both approaches work: spare branded batteries are the simplest, lightest option for long shoots. A multi-slot charger with a built-in power bank centralizes charging, reduces the number of separate devices, and is best when you have periods with no outlet and want to recharge multiple cells between sessions.
