Criteria Used for Evaluation

Capacity

You buy portable chargers so that they can provide decent battery charge and their capacity is measured by the number of times they can charge your smartphone or any other smart device. However, bear in mind that the type of the phone and the battery the phone integrates greatly influences the number of charging sessions you can expect from a particular charger. Their capacity is expressed in mAh, so the larger their mAh, the higher capacity they have. It is broadly accepted that a charger featuring 10 000 mAh is a solid average charger which can provide several charging sessions (in accordance with your device), so consequently, everything that is above it is considered to be of a high range and everything lower to be of less powerful capacity. The best portable charger on our list features a capacity of 25 000 mAh.

Effectiveness

The effectiveness of each of the devices was observed through a detailed analysis of the users’ comments and reviews provided by either those buyers who are more insightful into the electronics of these portable chargers or experts who have provided their expert opinion and detailed analysis. What we mean by effectiveness is the ability of these portable chargers to live up to the description given by the manufacturer. That means that when you would like to buy one of these products you know what to expect and to what extent that product will perform its purpose. As you can see, the best ones are highly effective in their ability to accomplish their task and feature a high level of functionality.

Features

There are a few basic features and a few extras that these portable chargers can boast about. The first one is the number of ports they have (USB and micro) and their charging speed. Within this criterion, we highly valued the smart technology that allows the charger to recognize the type of the device that is being charged and appropriately find the speed that is the most appropriate for that specific device. The lowest speed for a port is 1 amp and the highest is 2.4 amp. Secondly we considered the availability for wireless charging and only one portable chargers has this possibility in addition to all the others, and consequently, that portable charger is the first on the list. We also considered integrated accessories such as added cables or flashlights which increase the convenience of the products. Lastly, we took into account the possibility of the chargers to be charged while they are charging other devices since not all of them have this characteristic.

Compatibility

This criterion refers to the ability of the portable charger to charge multiple smart devices made by different manufacturers. Therefore, as you could perceive all of them provide the option for USB charging, and lightning charging for iPhones. Some also have micro ports and one has wireless charging feature. The possibility for multiple charging was observed and highly valued too.

Materials

The materials that these chargers are made from will ensure durability and high functionality and as a result, those materials were also scrutinized. What we specifically looked into was the type of the battery they feature, the type of protection they have integrated and the material of the casing which is especially important to protect the inside. The most effective and durable batteries are lithium batteries or Li-polymer ones which ensure endurance and consistency even after many charging cycles. The layers of protection and the IC safety protection from a power surge, circuit protection and overcharging is also an important factor that needs to be considered. Lastly, the protective case should be made of extra strong plastic or aluminum which is resistant to impacts and which provides utmost protection from external factors.

Frequently Asked Questions

q: My smartphone frequently runs out of power, so I was wondering what kind of power bank I need.

a:

If you need it just for your smartphone and if you use it occasionally, then any lightweight and smaller sized one to up to 10 000mAh will perfectly do the job. But, if there are other smart devices that you consider charging, then think of bigger ones.

q: My charger has a 200 mAh capacity. Is that enough for a full charge of my iPhone 7?

a:

Unfortunately, that capacity wouldn’t be enough for any smartphone, so you can expect to have it half charged or to maintain the battery to a workable level.

q: What is the difference between 1 amp and 2 amp USB port?

a:

1amp port has lower charging speed regardless of the capacity of your battery, while 2 amp is fast charging USB port that provides the fastest full-capacity battery.

q: Can I charge any other devices besides smartphones and tablets?

a:

Practically, everything that has a USB charging option can be charged by these portable chargers. This includes Bluetooth sets, Kindle, cameras, headphones, headsets, and laptops that feature this possibility.
