Key Considerations When Choosing a Multi-Device Power Bank
- Check Device Compatibility
Ensure the power bank supports Power Delivery (PD) or Quick Charge (QC) for your specific devices. - Look at the Port Options
USB-C is a must for fast charging modern devices, while USB-A is useful for older gadgets. - Balance Capacity and Size
A higher capacity means more recharges, but also more weight — find the sweet spot for portability. - Charging the Power Bank
Models with USB-C input/output usually recharge faster than older micro-USB models. - Airline Rules
If travelling, make sure the power bank is under 27,000mAh (100Wh) to comply with flight safety regulations.
