What Should You Look for When Choosing a Power Bank?

A power bank is no longer just an extra battery you pull out in an emergency. For many people, it has become a regular part of everyday life, alongside their phone and wallet. Still, there are significant differences between power banks when it comes to capacity, charging speed, ease of use and design. If you choose the wrong one, you may end up with a solution that is heavy, slow or simply impractical. 

In this guide, we take a closer look at what you should consider when choosing a power bank, and how different models from Happy Power cover different needs. 

How Much Capacity Do You Need? 

Capacity is measured in mAh and determines how many times you can charge your device before the power bank itself needs to be recharged. Many people automatically choose the highest possible capacity, but that is not always necessary. 

• 5,000 mAh is well suited for everyday use, short trips and as a reliable backup. 
• 10,000 mAh is ideal for travel, long days and for those who use their phone frequently. 

The Stockholm Powerbank and Bergen Powerbank both offer 5,000 mAh and provide up to 2–2.5 charges. This covers the needs of most people during a normal day. 

If you need more capacity, both the Oslo Powerbank and Copenhagen Powerbank offer 10,000 mAh, giving you more full charges and greater flexibility. 

How Fast Should a Power Bank Charge? 

Output power, measured in watts (W), has a big impact on how quickly a power bank can charge your devices. Higher output means shorter charging times, as long as your phone or tablet supports fast charging. 

• The Stockholm Powerbank delivers 15W and is well suited for stable, everyday charging. 
• The Bergen Powerbank delivers up to 22.5W and offers noticeably faster charging. 
• The Oslo Powerbank provides 35W and is ideal for fast charging of newer smartphones. 
• The Copenhagen Powerbank is the most powerful option in the range, delivering up to 45W. 

Ready to Use Without Extra Cables 

A power bank should be easy to use, even when you are on the move. Many people carry a power bank but forget the right cable. This is why built-in solutions have become increasingly popular. 

• The Oslo Powerbank has built-in USB-C and Lightning cables. 
• The Bergen Powerbank features a built-in dual pin for both USB-C and Lightning. 
• The Stockholm Powerbank supports both wireless Mag charging and fast charging via USB-C. 
• For maximum performance, the Copenhagen Powerbank supports both USB-C and Qi2 magnetic wireless charging. This makes it an excellent choice if you want fewer cables and the fastest possible charging. 

These solutions ensure that the power bank is always ready to use, whether you are at work, out in the city or traveling. 

Size and Design That Fit Everyday Life 

A power bank that’s left at home is of little use. That is why size and design should be part of your decision. 

The Stockholm Powerbank is a great example of a compact and discreet solution that combines a power bank and a wallet, with space for three cards. Its design also allows your phone to stand upright on a table while charging. The Bergen Powerbank is also small and lightweight, while the Oslo and Copenhagen Powerbank models offer more power without becoming impractically large. 

Can You Bring a Power Bank on a Plane? 

Many people are unsure whether it is allowed to bring a power bank on a plane. The rules are clear: power banks must be packed in carry-on luggage and stay within established capacity limits. 

All power banks from Happy Power comply with current airline carry-on regulations, making them safe to bring on both short and long trips. 

How Much Should a Good Power Bank Cost? 

There are large price differences between power banks, but a higher price does not always mean the product is right for you. 

• The Bergen Powerbank is an affordable and practical choice at 499 NOK. 
• The Oslo Powerbank offers more power and capacity at 799 NOK. 
• The Copenhagen Powerbank is the flagship model at 999 NOK, featuring high performance and wireless charging. 
• The Stockholm Powerbank is perfect if you want an all-in-one solution, also priced at 999 NOK. 

There is also a practical docking station available for the Bergen Powerbank, making it easy to keep the power bank charged and ready at home or in the office. 

Which Power Bank Is Right for You? 

The best power bank is not necessarily the biggest or most powerful one, but the one that fits your everyday life. If you use your phone a lot, travel frequently or want to carry as few accessories as possible. There is a solution that meets your needs.
