What should you consider before buying an external battery?
While the Puro 2400 mAh external battery is an excellent solution for emergency charging, there are certain key factors to consider when choosing the best portable battery for your personal needs. Below, we explain the most important ones:
- Capacity (mAh): This is the main value to consider. Keep in mind that the actual capacity of a power bank is typically 60-70% of the theoretical capacity, due to energy losses during conversion and internal efficiency. For example, a 2400 mAh battery will be ideal for one full charge or two partial charges on smartphones with batteries up to 2000 mAh.
- Weight and size: You have to find the right balance between portability and battery life. If you're looking to always carry it with you, a compact model like the Puro is perfect. For long trips or multiple devices, it's best to opt for a larger capacity, although this increases the size and weight.
- Type and number of ports: The more ports a battery has, the more devices you can charge at the same time. Check to see if they include USB-A, USB-C, or even wireless charging outputs for greater compatibility.
- Charging speed (amps – A): The Puro's 700mA output is standard for its age and size, but there are batteries that offer up to 2A or more for fast charging, compatible with accelerated charging devices.
- Materials and resistance: Look for cases that are resistant to bumps, drops, and scratches, especially if you tend to carry it in your purse or backpack.
- Charge indicators: A good LED system or display will let you know how much battery life is left, which is essential for planning your recharge.
Plus, more and more models offer extra features like a built-in flashlight, a clock/alarm clock, solar charging, or even the ability to charge and be charged simultaneously (pass-through charging). Choose a model that suits your lifestyle and guarantees compatibility with your current and future devices.
