The compatibility test is run on specific device models and software versions. Hardware or software updates may affect compatibility. A lot of people don’t know if they’re allowed to take power banks on planes or not. It is very important to know the Wh value of your power bank to comply with the rules and regulations referring to power banks and batteries in the travel industry. For example, you cannot take a battery exceeding 100Wh on planes. Common power bank capacities from mAh to Wh

This is because mercenary fraudsters are aware of the desirable nature of these mythical power banks and are preying on unsavvy consumers who will be allured by the idea of such a marvellous product.

It’s also worth mentioning the fact that if the voltage is smaller than the voltage of your device, charging cannot occur. This is why all power banks come with a step-up voltage converter to produce the 5 Volts required for charging an external device. The Anker Portable Power Station has a whopping capacity of 108000mAh! It has the capacity to power fridges, laptops, wifi routers, power drills and much more and can keep going for days and even weeks before it needs to be recharged!

Common power bank capacities from Wh to mAh

A: It depends on the power bank and laptop specifications. Some power banks offer Power Delivery support, which enables charging laptops with USB-C ports. Ensure the power bank’s output voltage and current are compatible with your laptop’s requirements. The biggest myth about cell phone power banks is that its power is listed in the technical specifications. If you see 10000mAh on a power bank or its user manual, you may assume it can charge your iPhone 11 (3110mAh) at least three times. Unfortunately, it's going to run out of juice before the third charge completes because the real capacity is only about two-thirds the size of the advertised volume. Realistically, a 10000mAh power bank only has around 6000~7000mAh of power to charge up your iPhone 11.

100000mAh power banks. Real or fake?

As the market for faster, longer lasting, more advanced and reliable technology grows, so does the demand for portable power banks that can support them and keep them running. Are 100000mAh Power Banks Fake? So it seems that there are multiple developing technologies that could have a great impact on batteries in general, and power banks in particular. As these technologies become mainstream, we should expect portable charger prices to gradually drop and the overall capacity to increase. Thus, it’s safe to assume that in a few years’ time, 100000mAh power banks will be quite as common as the 10000mAh options we have nowadays. Gallium Nitrate (GaN). Another emerging technology, GaN promises to deliver smaller, faster, and more efficient devices. Right now, it’s found applicability in wall chargers, but leading companies are trying to find ways to include it in portable battery chargers as well. This means smaller, faster power banks that will have higher capacities than currently possible.

As we come to rely more and more on smartphones and portable technology, the popularity and need for effective power banks is also increasing. If you want to do the conversion by hand, here’s the formula behind our Wh calculator: Wh = mAh × V / 1000 Pass-Through Charging: Choose a power bank that supports pass-through charging, allowing you to charge both the power bank and your device simultaneously.
