What is a Power Bank
People use more and more gadgets such as smartphones, tablets, mp3 players, smartwatches and many more on a daily basis. In order to make these gadgets compact and portable, manufacturers typically fit them with smaller and lighter batteries. The downside though is that the reduction in size has also resulted in a shorter battery life. This is where a power bank comes in handy. This small electronic device has been designed for charging your gadgets on the go no matter where you are. With a power bank, you are not bound to the sockets and can quickly bring back to life the dead battery of your phone or tablet. A power bank comprises a few batteries concealed inside the enclosure and features several USB-enabled built-in ports. In this review, you'll find some useful tips and guides on how to choose the right power bank that will match your needs and applications.
We would like to draw your attention to the best iPhones - the most famous Apple smartphones with the newest technologies and features. Additionally, if you want to charge all your gadgets organizing them in one place, opt for the right charging station.
What Features to Compare
Capacity and Output Current
The first thing you need to consider when selecting a power bank is its capacity. Measured in mAh, this spec shows the number of times your mobile device can be charged. What you should know, though, is that the bigger the power bank capacity is, the heavier the device will be. The current, measured in A (ampere), typically determines the charging speed. Usually, you will need 1A of output current to charge a smartphone and 2A to charge a tablet. As for the capacity, opt for 3000 mAh capacity power bank to be able to charge a smartphone and for 6000 mAh or higher to charge a tablet. If you use a lot of gadgets every day and you want to charge them with a single power bank, it's better to choose the model with greater capacity and several USB-enabled ports.
Compatibility and Functionality
Next, you want to pay attention to compatibility and functionality of the device. In case you need to charge more than one mobile device, you should consider models with several USB ports. Some extra bells and whistles like a flashlight and LED indicators will add to the versatility of use of the device. Also, some power banks may have additional adapters with the help of which it will be possible to charge even a laptop. All these extras may come very helpful when on a trip, for example.
The design of the power bank should not be overlooked. You will use it a lot, so, it should be well designed and produced from high-quality materials. Power banks enclosed in aluminum casings look great and are very pleasant to touch. Needless to say, they are also very durable. Even if you accidentally drop one, it won't break. Plastic models are more lightweight and usually come at a cheaper price. As we've mentioned above, high-capacity power banks are typically very bulky and therefore, may not suit your everyday needs. So, if you plan to carry one with you, the capacity of 15000 mAh will be the biggest one you'd want to have.
Flawless Combination of Design and Safety
This RAVPower model is one of the most up-to-date devices currently on the market and having purchased it, you will be able to feed all your mobile gadgets.
The main thing that makes this item stand out in its class is the housing. A fairly compact body (at 6.50" x 2.76" x 0.94", you can put it in a pocket, let alone a bag) is made of exceptionally durable fire-resistant thermoplastic alloy by Bayer, a material commonly used in luxury models of Mercedes-Benz and BMW cars. Inspires confidence that the bank will serve as long as German cars do.
Then, there are safety measures that manufacturer also didn't neglect. An NTC module monitors the battery temperature and constantly keeps it within limits while MCU offers over-charge and short-circuit protection. As for the built-in battery cells themselves, they went through an upgrade as well, compared to the traditional 18650 cells. The upgrade has resulted in a high efficiency when the device performs almost the same even after hundreds of times it was recharged.
Smart Charging Technologies in Your Pocket
Aside from design reliability, RAVPower engineers have also thought about implementing the newest charging technologies. One of them is the iSmart 2.0, a peculiar technology that automatically determines the optimal power for each gadget you connect to the bank. This allows the fastest charging you have ever seen, probably. And the device has 3 USB ports, 2.4A each, meaning you can charge up to 3 devices at a time. However, note that if you do use all three ports simultaneously, the max output will only be up to 5.8A.
With this portable charger, you will have enough power to fill either nine iPhones 6S, five Galaxy S7 smartphones, or three iPad Mini tablets (and have a bit power left with the latter). The process, at that, will be maintained by the Charging IC technology that ensures constant power level.

To prolong battery life, it’s easy to follow some simple tips that we’d like to share. Whenever you’re out of signal reach, power off your device or use it in the Airplane mode. This way you’ll not run a risk of phone running flat when you urgently need it. The thing is, when the signal isn’t there, smartphones still seek for it consuming a lot more power than they would under normal conditions. Therefore, it’s preferable to switch modes even there where the signal is just weak. Don’t use a ring and vibration mode unless you keep your phone in a pocket. It’s also advisable to deactivate all additional functions such as Wi-Fi, Bluetooth, etc. when they aren’t in use. Speaking about Internet connection, you mightn’t have known but GSM connection consumes much less power than 3G, thereby, sticking with the first will surely make up for battery capacity a lot. We hope that our recommendations were useful and now you’ll be able to get much more use out of your gadgets!
