Here are the best 20,000mAh power banks you can get on a budget.
Things to consider when buying a 20K power bank
How hard can it be to buy a power bank? Well, not much but we still want to prescribe the factors that help you get the best option for your device. Here are some of the things to consider:
- Build quality matters: You might not know this but power banks deliver better results based on their build quality. A good design ensures the internal heating is kept to a minimum, which results in better and more effective charging. Make sure the power bank you are buying won’t break apart.
- Multiple ports come in handy: Go for a power bank that carries multiple versions of USB ports. This way you can charge older and recent models that come with micro USB and USB C ports, respectively. These ports also mean you get the right amount of charging speed compatible with your device.
- Power discharge for better speed: Buyers should also read through the detailed specs of the power bank to make sure it supports the power discharge supported by their device for faster charging.
- Multi-level protection: Power banks are basically batteries and power control circuitry, wrapped inside a casing. That means a faulty power bank can heat up while charging or provide the wrong output current, harming your device. That’s why you should only go for models that offer a minimum of three or five-layer charging protection.
