It comfortably powered two smartphones and a small portable speaker for the entire duration of our weekend adventure.
However, the sheer size and weight make it less than ideal for everyday carry in a small purse or pocket. While it boasts a substantial capacity, its bulk is a significant compromise for casual users who only need a quick boost.

The build feels robust, suggesting it’s designed to withstand the bumps and scrapes of frequent use.
The two built-in ports offer decent versatility for charging more than one device concurrently. While it advertises fast charging, our tests indicated it performs more like a standard fast charger rather than a cutting-edge rapid one. The plastic casing, while durable, has a slightly glossy finish that can feel a bit slippery when your hands are dry.
This power bank is an excellent choice for long-haul travelers, campers, or anyone who needs a reliable power source for extended periods without access to mains electricity. It’s also a great option for families on the go, ensuring everyone’s devices stay charged.

Frequently Asked Questions
Can a 40000mah Power Bank Charge a Laptop?
Yes, many 40000mAh power banks can charge laptops. This depends heavily on the power bank’s output wattage. Laptops require higher power than smartphones. Look for USB Power Delivery (PD) ports. These ports should offer at least 45W or 65W output. Check the power bank’s specifications carefully. Ensure it lists laptop charging capability.
Always verify the wattage your specific laptop needs. Some high-performance gaming laptops may require more. The power bank’s total output is also a factor. If you charge multiple devices, the available power per port might decrease. A good 40000mAh power bank with sufficient USB-C PD output is your best bet for laptop charging.
How Long Does It Take to Fully Charge a 40000mah Power Bank?
Charging a 40000mAh power bank can take a significant amount of time. This varies greatly based on the input charger used. Using a standard 5W charger will take days. Using a fast charger with a high wattage is recommended. A 30W or 65W USB-C PD charger can speed things up considerably.
With a powerful 65W USB-C PD charger, it might take around 5-8 hours. This is still a long time, but much better than older methods. Some power banks support even faster charging protocols. Always check the power bank’s recommended input specifications. Using the correct charger ensures optimal charging speed and battery longevity.
Is 40000mah Too Big for Carry-on Luggage?
Generally, 40000mAh power banks are allowed in carry-on luggage. However, there are airline regulations to consider. Most airlines limit the capacity of lithium-ion batteries. The common limit is 100Wh (watt-hours). You need to convert the mAh to Wh to be sure.
To convert, use this formula: Wh = (mAh / 1000) * Voltage. Power banks typically use 3.7V or 3.8V. So, 40000mAh at 3.7V is about 148Wh. This is above the 100Wh limit for most airlines. You might need to check with your specific airline for their exact policy. Some may allow higher capacities with prior approval.
What Is the Difference Between Mah and Wh for Power Banks?
mAh (milliampere-hour) measures the battery’s capacity. It tells you how much current it can deliver over time. Wh (watt-hour) measures the total energy stored. It accounts for both current and voltage. Wh is a more accurate measure of total energy, especially when comparing batteries with different voltages.
For example, a 40000mAh power bank at 3.7V has about 148Wh of energy. A power bank with the same 40000mAh but at 5V would have 200Wh. This difference is why Wh is crucial for airline regulations. It’s the standard for measuring battery energy for travel safety. Always check Wh for carry-on limits.
How Many Times Can a 40000mah Power Bank Charge an iPhone?
A 40000mAh power bank can charge most iPhones many times. An average iPhone battery is around 3000-4500mAh. So, a 40000mAh power bank could theoretically charge an iPhone 8 to 13 times. This is a rough estimate, as actual charges vary.
Factors like charging efficiency, the phone’s battery health, and background app usage affect the number of charges. Power banks also lose some energy during the charging process. Expect slightly fewer charges than the theoretical maximum. Nevertheless, it provides ample power for extended trips without needing a wall outlet.
Final Verdict
For a reliable and powerful charging solution, we recommend the Anker PowerCore Essential PD 40000. It consistently delivers on its promise of high capacity and fast charging. Its robust build quality ensures durability, and Anker’s reputation for safety features provides peace of mind. The inclusion of multiple USB-C PD ports makes it versatile for charging various devices, including laptops. While it has a longer recharge time itself, its capacity and charging speeds for your gadgets make it an indispensable companion for travel and extended use.
