A smartphone case with a built-in battery is designed to provide additional power to the mobile device.

The versatility of the portable iPhone charger case is that it is both a power supply for your phone and a protective case. Currently, there are many different cases on the market, which, in addition to two main functions, are also capable of performing other, auxiliary ones. For example, there are cases with stands or car mounts. Attention is also paid to the design of accessories so as not to spoil the appearance of the gadgets.

In this article, we will tell you what the features and advantages of the Apple extra battery case are how to use it, and offer a mini-review of the best, in our opinion, charging cases.


What is a portable iPhone charger case?

The accessory, in principle, has a not so complex design. It has a built-in lithium polymer battery inside. As soon as the smartphone is placed inside, the connector is connected to the connector at the bottom of the gadget and all that remains is to press the power button to start the charging process. In addition, most models have LED indicators that allow you to see the amount of energy remaining in the case battery. Therefore, as soon as the case is discharged, you need to connect the micro USB cable and restore energy reserves. It should be noted that for some devices, the cable is not included and the accessory can be recharged by charging from the phone, connecting to a 220 W network or to a PC via a USB port.

Apple external battery case has a built-in lithium polymer battery inside. Place the phone in the case so that the connector mates with the connector on the bottom of the phone. Next, turn on the switch (on the back or front of the case) to start charging your phone. Many models of cases have LED indicators (from 1 to 4 lights) โ€“ they show the charge level … 25, 50, 75, 100%.

The covers are designed so that you have access to all buttons and connectors on your phone. In most models, where a cover covers the speaker, the sound is redirected from the bottom of the phone to the front.

The case is rechargeable for over 500 full cycles. A full cycle is a charge from 0% to 100%. Partial loops are not considered complete loops. After 500 cycles, the battery can deliver less than 75% of its original capacity. This is the norm for any product with a lithium polymer battery.

What is special about Apple portable battery?

The accessory has three important characteristics: mobility, protection, and the reserve of power necessary for the phone to function. Unlike external batteries, their size is truly portable. The case is like a second skin for a phone, it can merge with it into one whole. In doing so, you will receive power, security for your mobile, synchronization and convenient data transfer. You can restore the strength of the case by connecting it to an outlet.

In addition, the special feature of the cases is that they are much thinner than external batteries. They do not add any additional weight to your belongings while traveling. They do not add weight to the phone itself, but even if they do, it all depends on which model you choose. If with a battery with a capacity of 8000 mAh, then here you have to sacrifice lightness in favor of a large supply of power. However, many thin battery cases on the market are almost invisible on the phone. Moreover, their battery capacity is 5000 mAh.

Another great thing about battery cases is that unlike batteries, they will be with you wherever your iPhone is. You will not forget it in the car or in the hotel, you just need to put it on your phone and put the gadget in your pocket.

How to use Apple external battery case?

Regular case โ€“ phone charger light, compact, easy to carry, easy to use. If it has energy in its batteries, it can work on the principle of “smart” charging, providing power to the iPhone. Nevertheless, you can also use the button on the case to start charging. In any case, you will get a supply of charge for your mobile at a convenient time, and you will be able to protect your phone from external harm, such as moisture, sharp corners or hard surfaces. Just one case and you no longer have to worry about your smartphone’s battery problems. It could not be easier.

After the Apple extra battery case runs out, simply charge it fully using the included micro USB cable. In some models (with the same connector as the phone) – the cable is not supplied, such a case is charged by charging from the phone. You can charge the case from a 220 Volt network or from a computer via a USB port.
