What should you look out for when buying a good power bank?
There are a few things you should look out for when choosing a power bank. Power bank test reports emphasize the importance of capacity and charging times.
- Capacity in mAh
The capacity of a power bank is measured in milliampere hours (mAh) and indicates how much energy it can store. A higher capacity means that you can charge your devices more often before the power bank itself needs to be recharged. For longer trips or if you want to operate several devices, you should choose a power bank with a higher capacity. However, keep in mind that a higher capacity usually results in heavier and larger devices. Power banks with high capacities can usually be found in the top positions on power bank best lists. - Fast charging times
The charging time is crucial as it determines how quickly the power bank itself can be charged. A power bank with a fast charging time is particularly useful if you have little time and need your power bank to be ready for use again quickly. The Flex5 power bank from Ledlenser, for example, is fully recharged in just 140 minutes.
- Output power for fast charging of devices
Not only the charging time of the power bank is important, but also the output power, which determines how quickly your devices are charged. The output power is specified in watts (W). A higher output power means that compatible devices can be charged faster. Our recommendation for a power bank is to choose a model with an output of at least 5 watts. - Size & weight of power banks
The physical size and weight of a power bank are particularly important if you are on the move a lot. A lighter and more compact power bank is easier to transport, but may have less capacity and possibly a lower output power.
What connections do Ledlenser power banks have?
A distinction is made between the input ports and the output ports. Input ports are used to charge the power bank itself, while output ports are used to charge the end devices.
- Input port: Ledlenser uses Micro USB and USB-C as input. Type-C is more modern than Micro USB and enables faster power and data transfer. Flex3 and Flex7 use Micro USB to charge the power banks. The newer Flex5 and Flex10 models use USB-C, whereby the Flex10 can also be charged with Micro USB.
- Output port: All Ledlenser power banks have a USB output that is compatible with most small electronic devices. The two newer models Flex5 and Flex10 also offer charging of devices via USB Type-C.
What advantages do Ledlenser power banks offer?
In addition to the standard specifications, Ledlenser rechargeable power banks offer further advantages that make them special. This makes them perfect for outdoor use and for use together with other Ledlenser products.
- Flexible power banks with replaceable batteries
Ledlenser power banks are equipped with exchangeable standard rechargeable batteries in either 21700 or 18650 format, depending on the model. These batteries can be easily replaced, which is not only practical when the battery is exhausted, but also increases sustainability as the power bank does not have to be disposed of when the battery has reached the end of its service life.
In addition, these rechargeable batteries can be removed from the power bank and inserted directly into compatible Ledlenser lamps, which makes their use very flexible. The batteries also charge up to 30% faster when they are in the power bank compared to charging in the lamps themselves. These power banks also serve as a safe transport box for the batteries, as they are doubly protected against short circuits and other environmental influences thanks to IP65.
- Always informed thanks to charge level indicator
An integrated charge level indicator shows how full the battery is at all times. This means you are always informed about the current charge level and won't suddenly find yourself without power. This is particularly practical on longer trips into the countryside, as you can better manage your power consumption. - Protected from moisture and dust
Thanks to their IP65 certification, the power banks are both waterproof and dustproof. This protection makes them particularly suitable for use in harsh weather conditions, whether hiking, camping or at work. The robust construction not only protects the internal components, but also ensures that the power bank is ready for use in any weather. - Other features
Our power banks are approved for air travel and can therefore be carried in hand luggage without any concerns. Another special feature is the low current option, which enables the charging of devices with a very low charging current, such as Bluetooth headsets. This is a function that other good power banks do not offer and is particularly useful when you need to charge smaller devices on the go.
