Nowadays people are moving around with cell phones, are not they? And sometimes the battery does not last all day … The best solution is to use a portable charger to ensure that your smartphone stays on even when there is no outlet nearby. But when it comes to choosing a charger, you have to do a lot of research so you do not risk ruining your phone, see!

You need to keep an eye on the charge capacity, which is measured in mAh. It shows whether or not the charger can fully charge the battery. It works like this: if the battery of the phone has a capacity of 3.000 mAh, the charger must have at least 3,000 mAh also to have a full charge. If the charger has 6,000 mAh, for example, then it can offer two full loads. Now, if the capacity is 1,500 mAh, then you can only charge 50% of the battery.

Another important detail is the power, which is measured in W [SPEAK WATTS]. Pro mobile if charged, it is necessary that the electric current coming out of the battery is greater or equal to the charging power of the smartphone, ok? If it is smaller, the cell phone will not charge! This mAh and W information is in the manual or in the box.

And to facilitate, look at this tip!

Portable batteries lose their useful life over time, meaning they lose performance and load capacity. To make the charger last longer, just recharge the device when the power is completely finished. Oh, and do not forget to turn off your cell phone when recharging so you do not waste battery power!

The Hard Bank has 2 models of chargers, the Power Bank AS 802 (pictured), which is designed to allow you to stay connected anywhere, with 6600 mHa, has a USB port 2.1A and 1A, which allows simultaneous charging of two devices and features an LED emergency flashlight.


Even with the evolution of battery capacity in new smartphones and increasingly efficient modes of economy, the autonomy of the energy is still a problem for most users. Everything contributes to the energy depletion before the end of the day: games, video streaming , application update, hardware heating and others. However, with a series of simple measures it is possible to significantly extend the battery life of your device.

  • Decrease screen brightness

This tip is pretty obvious, but it should not be underestimated: today’s smartphones typically have a 5-inch or larger screen. The display is the main battery devourer of the device, so it will last longer if you decrease its brightness.

Open Settings and click “Display” or “Display”. Select “Brightness” and turn off auto brightness. Finally, move the regulator to the left until the brightness limit is acceptable to you. This can also be done from the shortcut menu.

  • Turn off Wi-Fi

When you leave home, your smartphone enables data transfer from your plan, but Wi-Fi is still active and searching for networks. This consumes unnecessary energy. So it’s always good to turn off Wi-Fi when you do not need it. To do so, there are two ways:

Download the notification bar with two fingers and long click the Wi-Fi symbol. Or go to the Settings, choose “Wi-Fi” and turn it off.

  • Turn off the GPS

If you do not need the location system for your smartphone, turn it off. Many apps constantly send your location in the background, which consumes a lot of battery power.

You turn off the GPS as follows: pull the notification bar with two fingers and click the “Location” symbol for a long time, or go to the settings and turn off the “Local” option. In the location menu you can see which app had access to the information lately.

  • Identify the battery devourers

It is not always immediately clear why the battery runs out faster in some days than in others. Android gives you a good overview of each application’s battery consumption and each process. Just go to Settings and select “Battery”. There will be listed all the consumer champion apps.

Click on one of them to get more information. Among other things, you can see how long an application has occupied the processor or how much data it has received. If an app has an unusually high consumption, it may help if you clean your cache. If that does not help, the best thing to do is to delete this application and find another one that consumes less energy.

  • Delete Animated Wallpapers

Although cute, animated wallpapers can drain your device’s power. It is therefore best to use a static backdrop.

  • Limit the synchronization in the background

Many applications and widgets update data in the background. Weather applications, for example, search for updated information at regular intervals. If this interval is too short, the battery will have to supply more power. Therefore, most applications offer the option to configure data synchronization intervals.

  • Disable automatic application updates

By default, the Google Play Store is set to automatically download app updates. This affects not only the volume of the data transfer, but also the battery.

To disable automatic updates, open “Google Play Store Settings” and click “Automatically update apps” and enable the “Do not update apps automatically” option.

  • Disable 4G

Do you have a smartphone with 4G but only a 3G plan? Or do not you just plug into the 4G in no way in some places? Then deactivate the fast network in the settings, so that it is not constantly searched.

To do this, open the “Settings” and choose the “More” point under “Wireless networks”. Then click on “Mobile Networks” and select “3G”.
