Portable mobile chargers or power banks are convenient ways to juice up your mobile devices, especially when the battery enters the red zone and you are not anywhere near a power socket. However, the market is flooded with so many products that it can become difficult for an average user to pick the right product.
Although your own budget and requirements are important in picking the right product, it’s highly recommended to stick with reputable brands. Let’s start with some important things to consider before moving on to our top 5 picks for the best power banks, which have been carefully selected keeping in view how much value you are getting for your hard-earned money.
Things to Consider When Buying a Power Bank, Traveling Mobile Charger
Buying a power bank is not such a complicated task, but you still have to consider a few things. The main purpose of buying a mobile charger is to be able to ‘quickly’ juice up your mobile device when you are not anywhere near a power socket. Power banks are not just about battery capacity anymore. Here are some of the most important things to consider in a power bank, which we’ll also use as a criterion to benchmark different products against each other.
Size and Capacity
The bigger the better is not always the best option in all situations. Battery capacity (mAh), size of a power bank and weight are all related to each other. Power banks that can easily fit in a pocket are usually good enough for completely charging a smartphone at least once. You have to strike the right balance between portability and capacity. If you need a large capacity power bank, then you also need a purse or bag to carry it around.
The easiest way to determine the battery capacity you need is to check how much charge your devices need. For example, if you only have one smartphone to charge that has a 3,000 mAh battery, then you might want to consider something around 5,000 mAh, which is considered to be a pocket-friendly size.
When talking about battery capacity, it’s worth mentioning that you can take external batteries on board an airplane that are less than 27027mAh. Another thing to keep in mind is that there is some loss in power conversion capacity. For example, a 5,000 mAh battery pack might have a 70% conversion rate, which effectively makes it a 3,500 mAh power bank. That’s why you should consider at least 30 percent more battery capacity than what you think you need.
Many consider input and output ports to be the second most important feature to consider. But charging speed becomes more important when you want to quickly get your mobile device out of the red zone (you need just one port for that). Different manufacturers use different charging technologies, which in some cases are only supported by the stock charger.
There are many fast charging technologies such as Qualcomm Quick Charge, which is supported on a variety of devices, while other technologies are proprietary such as Huawei, OnePlus and Oppo. There are two key specifications to consider when comparing different products and the charging speed.
The first is the Voltage, which is usually 5V for standard charging and 9V or 12V for fast charging. Then there is amperage, which refers to the amount of current flowing from the charger/power bank to the device. Voltage X Ampere gives you the measure of total power in Watts. The higher the wattage, the less time it should take to charge the device.
Some manufacturers boost voltage to charge quickly, while other boost amperage, but most vary voltage dynamically for fast charging. Power banks not compatible with the fast charging technology of a particular phone are designed to be backwards compatible and charge at standard 5V, which is slower but not too bad. Fast charging requires a compatible phone, battery, cable and a charger, so if anything is missing, it won’t charge in Fast/Turbo Mode.
The charging speed also depends on the USB generation being used as shown in the table below:
Max. Power (Watts)
5 to 20 V
Up to 100
Some of the most popular modern fast charging technologies include:
Fast charging Technology
Max Power (Watts)
Max Voltage (V)
Max Amperage (A)
USB PD (3.1)

Apple Fast Charging
Huawei SuperCharge 2.0
Huawei Super Charge
Select Oppo devices
Oppo Super VooC
Select Oppo devices
OnePlus Dash Charge
OnePlus supported devices (older)
MediaTek Pump Express 4.0
USB PD: USB Power Delivery is a modern fast charging standard (both ways) that offers power levels of up to 100W on supported devices.
Qualcomm QC: Developed by Qualcomm, Quick Charge is the most popular standard and used in devices that have a supported Snapdragon SoC. All QC standards are backwards compatible. Qualcomm QC is also used by other companies, including Motorola (Turbo Power).
Samsung Adaptive Fast Charging: Based on Qualcomm QC and compatible with QC fast chargers and power banks (previous gen).
MediaTek: Although MediaTek is Qualcomm’s competitor, many devices with a MediaTek SoC support Qualcomm QC technology, which is great for the end users.
Oppo VooC and OnePlus Dash Charge are compatible with each other, but these technologies are proprietary and not supported by 3rd-party power banks and chargers. Same is the case with Huawei SuperCharge, but it works with Qualcomm QC on certain devices.
Most mobile devices can be charged using a standard USB-A and newer USB-C port. You are likely to find both types of USB ports in modern power banks, but the number of ports you need mainly depends on the battery capacity and the number of devices you want to charge. If you have a device that uses a USB-C port, then you should buy a power bank that also has a USB-C output port. That’s because USB-C ports support more fast charging protocols, but not all power banks have USB-C output functionality.
Wireless Charging and Pass-through
Some portable mobile chargers and power banks support wireless charging, which allow you to charge supported mobile devices without using any cables. Qi is the most popular wireless standard compatible with Samsung and Apple devices, so make sure that the power bank is compatible with the wireless charging standard of your mobile device.
Pass-through refers to a useful feature that allows you to charge your mobile devices as well as the power bank at the same time. This feature comes handy when both the mobile devices and the power bank are low on power and you have access to a power outlet.
Battery Type and Other Features
It’s not possible for most users to judge the quality of a power bank just by looking at it. You also need to keep in mind that power banks contain cells or batteries, which can explode in certain situations. That’s why you should always pick a reputable brand. The two key battery technologies used in power banks include lithium-ion and lithium polymer.
Both technologies are similar, but lithium polymer batteries are more flexible, robust and last longer. Li-Po batteries are also very low profile and lightweight, which means thinner and lighter power banks with more capacity.
Style and finishing is a personal preference, but it’s better to avoid weird square-shaped or soda can shaped power banks that are difficult to carry around in a pocket. Depending on your requirements, there are some other features too that you might want to consider such as support for solar charging, built-in flashlight, FM radio and docking support, but these are not the features we’ll be focusing on in this post.

Anker PowerCore Fusion is a hybrid charger with a built-in 5,000mAh battery. Its main advantage is its size and form factor. It allows users to conveniently carry and use it as a wall charger as well as a battery pack. You get dual-port, high-speed wall charging and a portable battery in a compact package.
Better portability and a compact form factor means a compromise somewhere, which in this case is the battery capacity. 5,000 mAh is only good for charging a phone 1.5 times after which you have to plug the device into a socket. The battery pack is only good for smartphones and occasional/partial charging of other devices such as tablets. According to the manufacturer, when connected to an AC outlet, it charges the connected devices first before recharging the built-in battery (takes around 2.5 hours), which can be a pro or a con depending on who you ask.
