Criteria for choosing portable batteries for mobile devices, ten external batteries that fully comply with them


Most gadgets are exploited mercilessly by users. Often, one battery charge lasts half a day. If the owner of a smartphone is a fan of games, then this time is reduced even more. Therefore, in most cases, you cannot do without an external battery or a power bank. Before purchasing such a device, it is a good idea to familiarize yourself with the rules for choosing such products. Then you can choose for yourself one of several external batteries listed in the rating of our portal.

What to look for when choosing a portable storage device

To a user who is not familiar with the nuances of choosing external batteries, it seems that there is nothing difficult in this process. It is enough to choose the right capacity and size of such a gadget and that's it.

This is not quite the right approach. In practice, things are a little more complicated. Before you buy an external battery, you need to highlight a number of criteria, choose priority ones for yourself. These are the criteria.

1. Charging speed . It's not bad if the compact device has a capacity of 50,000 mAh. However, it is not entirely pleasant to wait if such a charger will do its job for a long time. What if it takes 8-10 hours to charge your smartphone? For many, this is unacceptable. Therefore, it is important that the powerbank maintains fast charging standards.

2. The capacity of the external memory. It should be understood that the choice of a more powerful device entails an increase in its size. It's not hard to find a powerful gadget, but due to its size, it will take up a lot of space in a backpack or bag. The best option is to buy a charger with a capacity of 5000 to 10000 mAh.

3. Availability of suitable ports and connectors. Not all remote batteries offered in retail chains are modern and advanced. There are also devices equipped with ports of outdated standards. For example, instead of the required USB-C, either USB-A or Micro-USB can be used, and it's also a good idea to pay attention to the number of available connectors. There shouldn't be too many of them, but one or two is not enough now.

4. Manufacturer's (brand) data. It is possible that the gadget of the company, which is not yet widely known, will last a long time. However, it is better to buy a product from trusted developers. Inexpensive and high-quality external storage devices are now produced by the brands Anker, Aukey, Xiaomi and some other companies.

5. Dimensions of the device. This was already mentioned above. The size of the gadget grows in direct proportion to its capacity. Sometimes it is enough to have a small external battery at hand for one-time charging of the smartphone. Others need a powerful battery that won't fit into every backpack. It all depends on preferences and relevance.
