Frequently Asked Questions
What should I look for in a portable charger and power bank?
The quality of different power banks can vary greatly, so it's best to stick with recognizable brands like Anker, Mophie, Belkin and the like. However, there are a few things you should always look out for when purchasing a power bank.
First, make sure the battery pack is Quick Charge 2.0, 3.0, or PD certified. Next, don't put too much faith in the company's claims that it can charge certain devices in a certain amount of time, such as the battery being able to charge an iPhone 15 in two hours. Pay more attention to battery capacity as well as weight and size. A large capacity in the 20,000 mAh range or higher should be sufficient for most small devices such as tablets or smartphones. Finally, make sure the power supply has all the necessary connectivity options – USB-A or USB-C, etc.
What battery capacity should you look for in a charger?
For a portable power bank that you can easily travel with, you should look for a battery with a minimum capacity of 10,000 mAh. Most models these days even offer 20,000mAh capacity at reasonable prices. The more mAh, the better. Just remember to match your capacity needs with the physical size of the power bank.
Typically, the more mAh a power bank has, the larger its physical size and the heavier it is. So we recommend that when choosing a power bank, you first consider the amount of power needed to charge your devices, and then adjust your expectations based on the size and weight you're willing to carry.
What is mAh capacity?
The mAh capacity (milliamps per hour) refers to the available capacity of the battery. A higher number means the battery can store more energy and has a longer lifespan when charging the device. For example, the iPhone 13 Pro Max battery has a capacity of 4352 mAh. This means the 10,000mAh battery can fully charge the phone just over two times before it runs out.
