Portable Chargers – Buying Guide

There are quite a few portable chargers a.k.a. power banks on the market nowadays so picking the right one might prove rather tricky.

After all, they all come in various shapes, sizes, capacities, features and of course prices.

That’s why in the coming paragraphs we’ll concentrate on the most important aspects of a portable charger to take into consideration when you’re buying one!

Power Capacity

Power banks come with all kinds of battery capacities e.g. from 3,500 mAh all the way up to 26,800 mAh and beyond.

And as you might imagine, the main difference is how many times the charger will be able to recharge your device to full.

For instance, a larger 26,800 mAh will be able to fully “revive” your smartphone up to 6 times, while a tiny 3,500 mAh charger will most likely recharge your phone to 100% just once.

So you have to figure out how long you’ll be out and about without access to electricity.

If you’re planning on camping for several days, then, by all means, do get a high-capacity charger.

Best portable charger, smartphone charged by a power bank


Some portable chargers are the same size as your smartphone (and they weight the same), while others tend to be quite bulky and heavy.

Some portable chargers weight only 5 oz, while others can go up to 17 oz and above.

Typically, larger capacity chargers are bigger, heavier and most likely won’t fit in your pocket.

While most low-capacity models can fit in any of your pockets nice and easy, without making you feel uncomfy.

And sometimes when you’re planning on hiking for hours, you’d want to carry as less weight as possible.

Fast Charging

Depending on the situation, you might want to recharge your mobile device as quickly as possible, without caring about the capacity, size or else.

This is where fast charging comes into play, and most of the time this technology utilizes an increase in the amperage or a varying voltage to optimize the overall wattage of the charger.

Some examples of fast charging technologies are the Qualcomm Quick Charge, the Anker VoltageBoost and Power IQ and the Samsung Adaptive Fast Charging.

Regardless, the charging circuit of your smartphone is what eventually determines whether it can be charger any quicker or not.

It doesn’t really matter if you have a mega potent battery charger that has a 5 Volts 2 Amp (5V/2A) output if your mobile devices handle only 5 Volts 1 Amp (5V/1A).

In fact, having a portable charger with a higher supply current than your smartphone’s battery capacity might damage your mobile device’s battery.

Safety Mechanisms

You shouldn’t neglect the safety aspect when it comes to portable chargers (or any battery charger for that matter) as they can be potentially dangerous.

You might have or you might haven’t heard stories about how the battery of a portable charger exploded.

This can happen when certain safety features such as short a circuit prevention and overcharging mechanism are absent, usually to reduce the cost of the product.

So to avoid any potential injuries, only look for portable chargers that offer complete charging protection.

Number of Input & Output Ports

As a general rule of thumb, the bigger the portable charger, the more total number of ports it’ll have (mainly output ports).

That’s essential if you’d like to charge more than one mobile device (or devices using a different USB standard) and even more so if you’d like to charge multiple devices simultaneously.

Using the USB-A standard for the output port/s is a common sight in most power banks, although some models have both a USB-A and USB-C ports.

Even better, some portable chargers have a USB-C port that works both as an input and output port adding a great deal of versatility.

What features should I look for in the best portable charger?

When searching for the best portable charger, consider its capacity, portability, charging speed, number of ports, and safety features.

Here are some things to look for:

  • A high-capacity charger will provide more charges for your devices.
  • Portability includes factors like size, weight, and design.
  • Charging speed is crucial for quick recharging.
  • Multiple ports allow you to charge multiple devices simultaneously.
  • Safety features like overcharge and short-circuit protection are essential for protecting your devices.

How long does it take to charge a device using a portable charger?

The charging time of a device using a portable charger depends on various factors, including the charger’s output power, the device’s battery capacity, and the charging cable’s quality.

Generally, a higher output power charger will charge your device faster.

For example, a 2.4A charger will charge your device quicker than a 1A charger.

Additionally, using a high-quality charging cable can also contribute to faster charging.

Can a portable charger charge multiple devices at once?

Yes, many portable chargers come with multiple ports that allow you to charge multiple devices simultaneously.

These chargers typically have a total output power that is shared among the ports.

It’s essential to check the charger’s specifications to ensure it can handle charging multiple devices simultaneously without compromising the charging speed or performance.

How many times can a portable charger recharge my device?

The number of times a portable charger can recharge your device depends on its capacity and the capacity of the device’s battery.

The capacity of portable chargers is typically measured in milliampere-hours (mAh) or watt-hours (Wh).

To estimate the number of charges, divide the charger’s capacity by the device’s battery capacity, accounting for efficiency losses during charging.

For example, a 10,000mAh charger can roughly recharge a smartphone with a 3,000mAh battery around three times.

Are there any safety precautions I should follow when using a portable charger?

Yes, it’s important to follow certain safety precautions when using a portable charger.

Some key recommendations include:

  • Use chargers from reputable brands and avoid cheap knockoff products.
  • Avoid exposing the charger to extreme temperatures, both hot and cold.
  • Disconnect the charger from the device once it’s fully charged.
  • Do not leave the charger unattended while charging.
  • Keep the charger away from water or other liquids.
  • If you notice any damage or unusual behavior from the charger, discontinue use and contact the manufacturer for assistance.
  • Read and follow the manufacturer’s instructions and guidelines for safe usage.

Are Power Banks Bad for Your Phone?

Not really – as long as the voltage and current of the portable charger match those of your smartphone.

Let me put things into perspective:

If the input of your phone is 5V/1A (voltage/current), the power bank should have similar values.

For example, using a charger that has a lower voltage will drain your smartphone’s battery, while a higher voltage rating will lead to an overload that will eventually damage the circuit your phone.

Most smartphones nowadays are best charged with a 5V voltage so for example if you’re using a 4.2V power bank, it’ll actually drain the battery of your phone.

So, always check what the current and voltage values on the original charger for your phone are.

Can a Power Bank Explode?

Yes, a power bank can explode just like any other device that’s powered by a lithium battery for that matter.

Here are some of the most common reasons that can make a portable charger go boom:

  • Poor battery quality – Although most manufacturers use either Lithium-ion or Lithium-Polymer batteries, some of the cut corners by putting recycled or counterfeit batteries in their power banks.
  • Improper usage – The way you maintain and take care of the battery of your mobile device is crucial as exposure to overcharging, high temperature and humidity are a big no-no.
  • Fault circuit design – A poor design of the circuit of a power bank may lead to temperature fluctuations, overvoltage and even short circuit.

Can a portable charger charge multiple devices simultaneously?

Yes, many portable chargers come with multiple ports, allowing you to charge multiple devices at the same time.

Make sure to check the specifications of the portable charger to ensure it has the desired number of ports.

Are portable chargers allowed on airplanes?

Yes, portable chargers are generally allowed on airplanes, both in carry-on luggage and checked baggage.

However, there are certain restrictions on the capacity of lithium-ion batteries that you can bring aboard.

It’s recommended to check with your airline’s guidelines to ensure compliance.

What is a Good Power Bank?

This is what makes a power bank (a.k.a. a portable charger) good:

  • Adequate power capacity
  • Compact size
  • Safety mechanisms
  • Sufficient number of ports (output and input)
  • Fast charging times
  • Decent price
  • Extra features (e.g. a built-in LED flashlight)

However, some of these aspects can be rather subjective like price and capacity as some people might prefer more expensive chargers (but with higher capacity).

While others might prioritize price over the outright power capacity of the power bank’s battery.


Eventually, based on offering the most optimal combination of power capacity, size, safety, features, ratings and price, the best portable charger and our personal favorite is the No products found..

It simply offers the absolute best value for money among high-quality power banks that are portable, powerful and reasonably compact.

Now, we’d like to know what YOUR favorite portable charger is?
