How to choose
Questions worth asking
Can a portable charger charge any laptop?
Most portable chargers use USB-C Power Delivery, which works with many modern laptops. However, some laptops require more than 100W or use proprietary charging ports. Check your laptop’s charging requirements before buying.
How long does it take to charge a laptop with a power bank?
Charging time depends on the power bank’s output and your laptop’s battery size. A 100W power bank can charge a 50Wh laptop in about 1 hour. Lower wattage will take longer.
Are portable laptop chargers allowed on planes?
Yes, but they must be in carry-on luggage. The FAA and most airlines limit power banks to 100 watt-hours (Wh). You can calculate Wh by multiplying the voltage (usually 3.7V) by the mAh and dividing by 1000.
What is the difference between USB-C PD and regular USB?
USB-C Power Delivery (PD) is a fast-charging protocol that allows higher power transfer up to 240W. Regular USB typically provides only 5V at 1-2A, which is insufficient for laptops.
Can I charge my laptop and phone at the same time?
Yes, most power banks with multiple ports can charge multiple devices simultaneously, but the total output is shared. For example, a 140W power bank might deliver 100W to a laptop and 40W to a phone.
How many times can a 20,000mAh power bank charge a laptop?
A 20,000mAh power bank has about 74Wh of energy (assuming 3.7V). A typical laptop battery is around 50Wh, so it can charge it about 1.5 times. Actual number varies due to power loss.
What is pass-through charging?
Pass-through charging allows you to plug the power bank into an outlet while it is also charging your devices. This is useful when you have limited outlets but need to charge both your power bank and laptop.
Are power banks safe to use overnight?
Most quality power banks have safety features that stop charging when the battery is full. However, it is generally recommended not to leave them charging unattended for long periods to avoid any risk.
Why is my laptop not charging from the power bank?
Check if the power bank supports the wattage your laptop needs. Some laptops require a specific voltage and current. Also ensure the cable is rated for power delivery and is not faulty. Try a different port or cable.
Our pick
For most people, the Anker 737 Power Bank is the clear winner because it offers high power, reliable performance, and a great feature set. If you prioritize a slim design, the Baseus Blade is an excellent alternative. Budget-conscious buyers should consider the INIU 140W, which provides similar specs at a lower cost. If you must have an AC outlet, the Mophie or Omni 20 are your only options, but they are heavier and less powerful. In short, pick the Anker 737 for the best balance of power and portability.
