What are the best Power Banks in 2020?

1. Anker PowerCore 20.100 mAh

Power bank with an extremely high capacity

When choosing a mobile power bank, you should pay attention to the capacity. The higher it is, the more charging cycles you can carry out. The Anker PowerCore Powerbank is a model that is one of the bestsellers on Amazon and has a capacity of up to 26,800 mAh.

The manufacturer Anker offers this power bank in four different capacities and three colors to order. What is interesting about this portable charger is its compact design. With a length of 16.6 centimeters, it is only slightly longer than a normal triangle, which usually measures 14 centimeters. With a width of 5.8 centimeters and a height of 2.2 centimeters, the narrow device fits well in your pocket.

This power bank supports PowerIQ technology, which allows quick-charging for those electronics devices that allow it. PowerIQ is a fast charging technology specially developed by Anker that recognizes your connected hardware and adjusts the charging current accordingly. Any device, whether from Samsung, Apple, Kindle or another brand, can be charged as quickly as possible.

The weight of the Anker PowerCore Powerbank is 355 grams, so it can be conveniently stowed away for mobile use or for transport. Anker also provides a certified security for this model. Thanks to the multi-protection safety system, connected devices are protected to the maximum, so that overvoltage short circuits or the like cannot occur.

How often can I charge my smartphone with the Anker PowerCore power bank?

How often you can charge your smartphone or other devices with this power bank until the battery of the power bank is empty depends on how high the battery capacity of the device to be charged is.

Does the device discharge when not in use?

No, the Anker PowerCore power bank does not discharge itself automatically when it is not being used. You can charge it a few days before and use it later. After a long charge, you should still check the charge level beforehand as a precaution.

Can I charge and use the power bank at the same time (pass-through)?

No, the Anker PowerCore Powerbank does not have a pass-through mode. However, this is also generally unnecessary for a power bank: If you already have an outlet for charging the power bank, you can plug your smartphone or other device into it as long as the battery of the power bank is charging.

4. Anker PowerCore 5,000 mAh power bank

Super compact portable charger

If a small power bank is an option for you, the PowerCore model from Anker is more suitable for you. The tube-shaped device measures only 10.8 centimeters in length and 3.3 centimeters in diameter and therefore fits in any jacket or pocket. It is lightweight at just 90.7 grams. This external battery with 5,000 mAh, for example, charges the Apple iPhone 6S twice and the Samsung Galaxy S7 completely at least once. Here you benefit more from a particularly compact design, with which you can ensure a short energy boost. However, if you have to live without an outlet for several days, this model is not suitable.

Just like the much bigger brother of the Anker PowerCore, this model also offers the manufacturer’s practical high-speed charging technology (PowerIQ). The device is based on two charging techniques so that each device can be charged as quickly as possible: The combination of VoltageBoost, which prevents cable resistance, and PowerIQ ensures the fastest possible charging of your devices.

Can I charge my cell phone while the power bank is charging?

No, this power bank does not have a pass-through mode. No other device can be plugged in while the power bank is charging.

How stable is this power bank?

The Anker PowerCore is made of robust plastic and is well suited for outdoor use.

Does the device discharge when not in use?

This power bank loses little battery capacity even if it is not used for a long time. It can be stored for several weeks without major losses. Nonetheless, you should check the charge level before use to be on the safe side.

How quickly can the PowerCore be fully charged?

Due to the low battery capacity, a full charge does not take much longer than charging a smartphone. You can expect a charging time of around 2 hours.

All You Need To Know About Power Banks

The Capacity of a Power Bank

Many consumers ask themselves before buying what capacity the battery of the power bank should have when it comes to charging certain devices. Basically, the simple 1 × 1 is not to be used here. For example, if your cell phone’s battery has 2,000 mAh, you cannot charge it five times if you have a power bank with a capacity of 10,000 mAh (5 x 2,000 mAh = 10,000 mAh).

In this example, it is more the case that the smartphone can only be charged three to three and a half times with such a power bank. This is primarily due to the fact that the power bank’s battery loses energy in the form of heat during the charging process, which can then no longer be passed on to the connected devices. A basic distinction must therefore be made in terms of capacity and available energy.

You have surely already noticed that after using a smartphone you will notice a drop in performance in terms of battery for a longer period of time. This is related to the age or use of the battery. The capacity of the built-in batteries will decrease over time. This also reduces the energy that can be stored in the batteries in relation to the power bank and passed on to connected devices.

4 Mistakes to Avoid When Charging a Power Bank

Basically, power banks are not dangerous if you pay attention to the correct operation. However, there are some sources of error that you shouldn’t neglect. We have explained four errors, which not only apply to power banks themselves, but also to all other electronic devices that have an internal battery, such as smartphones, notebooks or tablet computers.

1. Avoid Extreme Temperatures

High temperature fluctuations are one of the biggest reasons why batteries can be defective or not as powerful as before. This affects both cold and heat. Make sure that you do not leave your power bank in the blazing sun and do not use it in strong freezing temperatures without protection. Otherwise it may be the case that the battery of the power bank is damaged and can no longer be used as usual.

2. Switch off the Power Bank after Charging

Fortunately, you do not need to follow this tip for the portable chargers explained in this article because they have appropriate protective functions, but it is important if you have a no-name device from overseas.

If the charging process of the battery of the power bank is done, please switch off the device. The power bank should not continue to be supplied with electricity, as this can lead to damage, such as overheating.

With Power Banks without any charging protection and particularly cheap power banks from the Far East, you need to make ensure to unplug it as soon as it is fully charged.

3. Do not use USB devices if the Power Bank is getting too hot

If you think that that the power bank is unusually hot, it may indicate an internal defect. For safety reasons, it is therefore advisable that you stop any charging and replace the device or send it to the manufacturer as defective. Corresponding damage often occurs even after the power bank has been improperly treated.

4. Check your Power Bank for any damage after a drop

If the power bank falls on the floor, it can lead to damage. Under no circumstances should lithium-ion batteries with external damage be used. It is recommended to use a special bag to optimally protect the power bank. Some manufacturers use systems that go with it, so that the internal battery can be given maximum protection in the event of a fall.

General information on Choosing a Power Bank

If you are just wondering which power bank makes the most sense for you, you should pay particular attention to branded products and customer testimonials that are available to you, for example, in the Amazon online shop. You can determine what the experiences of the consumer are in practice over a longer period of time. The majority of the power banks presented above are good branded devices from well-known manufacturers that have proven themselves on the market for years.

Proper handling also plays an important role. To do this, you should pay attention to the sources of error described above and use the battery gently.You can then have maximum enjoyment from your power bank over a very long period of time and can use it to supply all electronic devices of your choice with energy on the go.

Using Power Banks Outdoors - What Should You Consider?

If you buy a power bank, you usually want to use it on the go or outdoors, where there are no sockets. In order to ensure a long lifespan for the power bank, the following three points should be considered when using it outdoors:

1. No Extreme Temperatures

It is best not to expose your power bank to extreme temperatures, as this will damage the battery and its capacity in the long term. If it is very cold outside, it is best to carry the power bank with you in your pocket. In addition, like all technical devices, power banks must not be left in the blazing sun. Find a spot in the shade for your power bank in summer, it will thank you!

2. Watch Out for the Rain

Very few power banks like rain or even falling into a lake. Therefore, you should always protect your power bank, just like your smartphone, from moisture.

3. Watch out what else you have in your pocket

Although many power banks come with sleeves or bags and can be purchased separately, they are actually not necessary in everyday life. Power banks are sturdy enough to be carried in your trouser or pocket or in your backpack.

However, you should pay attention to what else you have in your pocket. Pointy and sharp objects, magnets, stones, pieces of metal and the like can damage your power bank. As a rule of thumb, do not carry anything in your pocket with the power bank that you would not carry in a pocket with your smartphone.

Power Banks in Airplanes - What to consider?

Have you just booked a vacation and maybe read that power banks are not allowed on the plane? 

Basically, there are no general rules regarding the carrying of a power bank in aircraft. There are guidelines from the airline organizations, but in practice these are not implemented by all airlines. They only represent information that the airlines generally do not follow.

To determine whether your power bank is below the maximum limit of 100 watt hours, you need to do a simple conversion. Simply multiply the capacity of the battery in the power bank in mAh x the voltage in volts. You must then divide the result by 1,000 to get the watt-hours as a results. To do this, you can use the example calculation shown here:

10,000 mAh x 5 volts / 1,000 = 50 watt hours – You might be allowed to carry the portable charger on the airplane.
