The build quality feels robust, with a textured finish that provides a good grip.

The design is sleek, with a matte finish that resists fingerprints. I found the subtle textured grip to be effective, even when my hands were a bit sweaty.

The unit has a clean, minimalist design with a matte black finish that feels good in the hand.

Frequently Asked Questions
Can I Use a 100w Power Bank to Charge My Phone?
Yes, you absolutely can. A 100W power bank is designed to provide high power output. It will safely charge your smartphone, even if your phone doesn’t support 100W charging itself.
The power bank will communicate with your phone. It will negotiate the maximum safe charging speed that both the power bank and your phone can handle. This ensures your phone charges efficiently without any risk of damage. Most modern phones benefit from fast charging technologies.
Will a 100w Power Bank Charge a Laptop?
This is the primary use case for a 100W power bank. Most modern laptops, especially ultrabooks and many gaming laptops, can be charged via USB-C Power Delivery (PD). A 100W output is sufficient for most of these devices.
Always check your laptop’s charging specifications. Ensure it supports charging via USB-C PD and confirm the wattage it requires. Some very high-performance or specialized laptops might need more than 100W, but this is rare for typical consumer models.
How Long Does It Take to Recharge a 100w Power Bank?
Recharge time varies greatly depending on the power bank’s capacity and its input charging speed. A large capacity (e.g., 30,000mAh or 50,000mAh) will take several hours to recharge. This can range from 3 to 8 hours or more.
To minimize recharge time, use a high-wattage USB-C PD charger (ideally 60W or 100W). Using a standard phone charger will take significantly longer. Some power banks include a fast charger to speed up the process.
Are 100w Power Banks Safe to Travel with?
Yes, 100W power banks are generally safe for air travel, but there are specific regulations. Most airlines allow portable lithium-ion batteries up to 100Wh (watt-hours) in carry-on luggage. You cannot check them in your checked baggage.
A 100W power bank typically falls within this limit (e.g., a 20,000mAh 3.7V battery is about 74Wh). Always check the specific airline’s policy before flying, as rules can vary. Keep the power bank easily accessible for security checks.
What Is the Difference Between 100w and Other Power Bank Wattages?
The main difference is the speed at which devices can be charged and the types of devices that can be powered. A 100W power bank can charge power-hungry devices like laptops at their maximum speed. Lower wattage power banks (e.g., 18W, 45W) are suitable for phones and tablets.
A 100W output is significantly faster for compatible devices than lower wattages. It can also charge multiple devices simultaneously, provided the total output doesn’t exceed the power bank’s capabilities. For laptops, 100W is often the minimum required for efficient charging.
Final Verdict
For the best all-around 100W power bank, we recommend the Anker 737 Power Bank (PowerCore 24K). It consistently delivers 100W output, has a substantial 24,000mAh capacity, and supports rapid recharging. Its robust build quality and comprehensive safety features make it a reliable choice for charging laptops, tablets, and multiple phones simultaneously. It strikes an excellent balance between portability, power, and convenience.
