Best Portable Charger - Top 5 Reviews And Buying Tips 2021

There are a few things that are more frustrating than running out of charge in an area where there is no immediate access to power outlets. Be it a phone, a tablet, or any other type of electronic device, it is inevitable that the battery will run out at some point during your trip. The solution to this is to bring a portable charger with you. These practical devices serve as a convenient backup for your device battery and are often equipped with a number of great features that contribute to boosting the overall performance of your phones, tablets, and even laptops. In this guide, we will go over the essential features of portable chargers and we will help you pick the best option on the market in 2021.

Best Portable Charger Buying Guide

As it is the case with any type of electronic device, portable chargers come with a wide range of features and specs that can be confusing to a novice user. While some of these characteristics are essential and highly integral to the overall functionality of the unit, a great percentage of them is nothing more than superfluous functions that are used to inflate the price. To help you navigate this market and figure it out how to assess the intrinsic value of portable chargers, we have narrowed all the features that you need to focus on to these few points.

The charging time

This is a fairly intuitive feature. A portable power bank is supposed to add convenience to your life by providing with quick charging for all your devices regardless of where you are. In order to achieve this, the charger needs to have the capacity to deliver a full charge within a reasonable time frame. It is also essential to keep in mind that the charging time is not entirely dependent on the quality of the charger itself.  In a lot of cases, a poorly-designed or defective battery will take too long to charge even when you are using a high-end portable power bank to charge it.

The capacity

The capacity of the portable charger is one of the first things that you should pay attention to. It is generally correlated with size, so the bigger the charger is the higher its capacity. The power banks that can provide enough power for more than a day of continuous use tend to be significantly bulkier and heavier than the ones destined to power a phone for a few hours.

As for the actual capacity, it is usually represented in mAh, a unit of electric charge that measures power over time. The standard capacity for small chargers is around 3,500 mAh, whereas larger models can easily exceed 20,000. If you want to power bank that can provide you with enough power when you are completely off the grid for a few days, you should be looking at a unit that boasts a minimum capacity of 15,000 mAh.

The output and input ports

This might not seem like an important factor at first glance, but having a clear idea about the types of input and output ports that are included in a portable charger is extremely valuable. This will help determine its compatibility with your devices as well as the charging speed that it can offer. Neglecting this critical aspect will inevitably lead you to buy a charger that is not suitable for your needs.

When it comes to ports, there are only two options that you should familiarize yourself with; USB-A and USB-C. While the first option has its own set of benefits, USB-C ports are generally recommended due to their ability to deliver fast charging times. This is mostly due to the fact that both input and output are consolidated into one port, which results in quicker power transmission from the charger to the battery.

The cables

Cables are an important factor that has direct implications for the functionality of the power charger. Their quality will determine the unit’s ability to deliver a reliable charge to all your devices. More importantly, well-made cables can protect them from overheating and other power surge issues. To make sure that you are getting good quality cables, inquire about their thickness and ruggedness before making a purchase decision.

Pass-through charging wireless charging

These features are extremely valuable and they add a lot of practicality to the portable charger. The pass-through charging function allows you to charge your devices while the power bank is in charge mode. This comes in really handy when you want to use your phone without unplugging it or waiting for it to be fully charged. As for wireless charging, it is mostly designed for Samsung and Apple phones. Its main purpose is to eliminate the reliance on physical wires and provide a faster and more seamless charging. The most common wireless charging standard is QI.

The quality of the display

The screen display is a highly important component of any portable power charger. A good one should give a clear and easy reading of all the data that is relevant to the charge status of the battery. If you want to avoid the terrible user experience that is associated with poor quality displays, you need to make sure that the screen is wide enough to provide good visibility.

Maintenance requirements

A common mistake that many users make is purchasing a power bank without inquiring about its maintenance requirements. It is important to note that some models necessitate constant maintenance as well as some degree of know-how and technical prerequisites, whereas others are extremely easy to maintain. In order to ensure that the charger you get is in the second category, check some of the reviews left by users who purchased the same product. This will give you a reliable firsthand account of what to expect.

Safety features

Batteries of all types are exposed to a number of risks that are engendered by a power surge and electrical current issues. The most common of these include over current, over voltage, and over-charge/discharge. If you want to avoid these potential problems, your portable charger should come equipped with built-in features that safeguard the battery every time it is plugged in. These features protect the battery by regulating power output and maintaining the charge at the optimal level that is required to operate the device. Models that lack these features run the risk of encountering these issues within a few months of use.

The warranty

Due to the relative complexity of these devices, it is recommended that you opt for an option that is backed by a good warranty. Power chargers are prone to experiencing several malfunctions that are related to electrical current issues, so having a comprehensive warranty that safeguards you against this potential problem is simply invaluable.

Frequently asked questions

1 – Should I get a battery case or a portable charger?

This question is often asked by people who are not sure about the differences between these two devices. The reality of the matter is that each option is ideal for certain uses. If you feel that you are prone to forgetting your backup battery when you are heading out, a battery case might be the right option for you. On the other hand, the charging capabilities of these units are often underwhelming, especially when compared to portable power banks.

As we have mentioned previously, the best decision that you could make is to opt for an option that has low maintenance requirements. With that being said, there are still some precautions that you need to take if you want to ensure a smooth and safe use. The main one is to register your device by providing the serial number that comes with the package. This will activate your returns policy and ensure that the product you purchased is not counterfeit.

3 – Can I charge multiple devices at the same time?

This will depend on two variables; the capacity of the charger and the number of USB ports that it is equipped with. For a unit to offer simultaneous charging of multiple devices, it needs to feature multiple ports and must boast a capacity that exceeds the 10,000 mAh mark.
