50000mAh power bank can charge a laptop, but its ability to do so depends on the laptop's power requirements and the power bank's output specifications. High-capacity power banks like the 50000mAh ones are often designed to be compatible with laptops and can provide multiple charges.
Factors to Consider:
Capacity:
A 50000mAh power bank (or 185Wh) has a large capacity and can usually provide multiple full charges to a laptop.
Power Output:
Laptops need a higher voltage and wattage compared to smartphones. Look for a power bank that supports the voltage and wattage your laptop requires, often indicated by the laptop's charging adapter.
USB-C PD:
USB-C Power Delivery (PD) is a common protocol for charging laptops, so a power bank with USB-C PD output is a good choice.
