Power Banks for Laptops, Phones, Smart Electronics

A power bank will help you keep your mobile phone, smartwatch, tablet or even your laptop on standby at home or on the go. It serves as an energy storage and external battery that you can use wherever you don't have access to the power grid. For example, it is suitable for trips outdoors, on the plane or at an open air festival.

In our range of powerbanks you will find:

  • Classic wired power banks, including our unique 30,000 mAh power bank.
  • Practical wireless power banks.
  • Power banks with one of our fast charging systems, such as Power Delivery for Apple or Qualcomm 3.0 Quick Charge for Android.
  • Power banks with all types of connectors you might need. For example, USB-C, Lightning and more.
  • Power banks with capacities from 5,000 mAh up to 30,000 mAh.
  • Power banks for mobile phones, tablets and even laptops.

Most power banks usually have a cable that can be used to charge them. Additional cables, that can be used to connect the device to be charged, usually have to be purchased separately.

The capacity of a power bank may be of interest to you as it determines how many times you can charge your phone or how many devices you can charge at once. Other parameters, such as output current, size and connector types are practically similar to those of conventional wired or wireless chargers. What should I look for when choosing a power bank? We'll give you some advice in our quick guide:

How to choose a power bank? 

Do you need to charge mobile phones, MP3 players, wireless headphones, smartwatches, but also laptops or tablets, all without a mains connection? A power bank, a kind of external battery for your electronics, can help. When choosing one, look for capacity, charging power, dimensions and weight. You need to charge the power bank too. A micro USB cable is usually included.

 

What to look for when choosing a power bank?

To make sure your power bank serves you as you want it to, there are a few things to think about before choosing one. First of all:

  • What devices do you plan to charge with the power bank?
  • What capacity should the power bank have?
  • Will you be using it only at home or at work, or even on the road?
  • Do you need fast charging or is a normal speed enough?
  • Are you limited by price?

Battery capacity

The most important part of a power bank is the battery. Its capacity determines how many devices you can charge from the power bank and how long the power bank will last. The battery capacity of a power bank is expressed in mAh (milliampere hour) and indicates how much current the power bank will be able to supply for how long. For example, a capacity of 2,000 mAh means that the power bank will be able to deliver 2,000 mA for one hour, or 1,000 mA for 2 hours, or even 0.5 mA for 4 hours, etc.

How many mAh do you need to charge your mobile phone?

That depends on the capacity of its battery. You can usually find this information in the device's parameters when you buy it. Again, look for a number with a mAh number. For example, if your phone has a capacity of 2,500 mAh, that means you can charge it 2 times from a 5,000 mAh power bank. Actually, it's more like 1x, because the capacity claimed by power bank manufacturers is usually about 30% to 40% higher than the power bank can actually deliver. From this point of view, it would seem that it is best to choose a power bank with the maximum possible capacity. But realistically, you have to take into account that as the capacity increases, the size and weight of the power bank also increases and it might not be a small device that fits in your pocket.

Ideal power bank battery capacity

  • With a power bank up to 5,000 mAh, you can charge your phone once, maybe even together with a smartwatch or mp3 player. A cheap 5,000 mAh power bank is perfect for travelling because it is light and compact.
  • Power banks above 5,000 mAh and up to 15,000 mAh can charge your phone up to 3 times and are therefore ideal for long stays in the outdoors. If you focus on accessories, the 10,000mAh power bank can also serve as a flashlight in your tent. The 15,000 mAh capacity is also enough to charge a tablet, where you have, for example, a navigation device.
  • With a power bank with a capacity of more than 15,000 mAh, you can charge your laptop, charge your mobile phone up to 10 times, and even charge your smartwatch or Bluetooth headset. The 30,000 mAh power bank with the Power delivery fast charging function will provide enough power for your MacBook, iPhone but also your Apple Watch or you can use it both at home and on trips away from civilisation for several days.

What types of powerbank can you choose from?

If you only need to charge your phone occasionally, even when you're away from the mains, you'll be fine with:

  • A power bank with a charging cable with a USB output and a capacity of up to 5,000 mAh. Get a cable compatible with your type of device. If you're looking for a special power bank that gives you more convenience, and you're not afraid to pay extra for it, you can choose from the following types:

 

  • Wireless power banks

They charge your mobile phone, tablet or headphones without the use of cables. Wireless power banks work on the principle of Qi technology, which uses electromagnetic induction. The condition for its proper functioning is the stable attachment of two coils to each other within a distance of no more than a few millimetres. One of the coils is in the charging pad and the other in the device being charged.

  • power banks for tablets

This type of power bank has a capacity of at least 20,000 mAh. Tablet power banks very often also offer Quick Charge 3.0 for Android tablets or Power delivery for Apple tablets.

  • power banks for laptops

For effective laptop charging from a power bank, choose a capacity of at least 20,000 mAh, optimally at least 30,000 mAh. Laptops are already big energy consumers, and if you don't want to be left completely without power when you're away from the mains, investing in a high-capacity power bank is definitely worth it. Support for fast charging should be a must in this case.

  • power banks with fast charging 

Fast charging is needed for power banks if you don't want to wait and need to have your phone, tablet or laptop charged again in the shortest possible time. For Android devices, power banks with fast charging should have Qualcomm Quick Charge 3.0 protocol, for Apple devices look for Power delivery. It is important to note that the fast charging is supported by your device and that the cable is compatible. For example, to fast charge your Apple iPhone 8, you'll need a cable with USB-C/Lightning connectors.
