Choosing a Battery Charger Portable Power Bank

If you don't want to be left in the dark when your smartphone or tablet battery runs low, a power bank is an easy solution. But with so many options available, how do you know which one is right for you? In this article, we look at the features to consider when choosing a battery charger portable power bank.

Unlike a rechargeable cell phone battery, which degrades over time even when not used, power banks are designed to be regularly charged and discharged as needed. This is why it's important to keep in mind the number of charge-discharge cycles that a battery charger portable power bank can expect to undergo over its lifetime, as this is a good indication of how long it will last.

The average power bank is capable of completing 300-500 charge-discharge cycles, or roughly 1.5 years of use, before reaching its end of life. Keeping this in mind when shopping for a new power bank will ensure that you're getting the most out of it, and help avoid the frustration of purchasing a device that will quickly lose its charging capacity.

The first thing to consider when shopping for a power bank is how much battery capacity you need. This is typically indicated by a unit of measurement called milliamp hours (mAh). Smaller models are usually pocket-sized, while larger ones may be too big to fit comfortably in your hand or bag. You'll also want to consider the type and number of devices you plan to charge. If you only need to keep a single phone charged, a smaller model will suffice, with a maximum capacity of around 10,000mAh and charging speeds of 15 to 45 watts. If you'll be charging multiple devices, a larger battery pack is better suited to your needs, with a maximum capacity of around 25,000mAh and speeds of 65 to 100 watts or more.

Another factor to consider is whether the power bank supports fast charging, which can significantly reduce how long it takes for the battery pack to fully charge your smartphone or tablet. This can be difficult to confirm without checking your device's specs or manufacturer's website, but a high-quality power bank should list support for fast charging on its packaging or within its user manual.

A good battery charger portable power bank should have a micro-USB input port for charging itself, and at least one USB output port to charge your other devices. It should also have a status light to indicate the current state of charge and be protected from overheating, short circuits, and other issues.

Lastly, the battery charger portable power bank should come with a warranty, which can be a peace of mind for consumers. A good warranty should cover the power bank for a reasonable amount of time after purchase, and often requires that the buyer register the serial number or provide proof of purchase via a helpline or online portal to activate it.
