Which Power Bank Suits Your Needs?

Nitecore NB10000 – The Ultra-Light Champion

At 150 g and 10,000 mAh, the Nitecore NB10000 is one of the lightest power banks in its capacity class. USB-C PD and QC 3.0 ensure fast charging. Perfect for ultralight trekkers, trail runners and bikepackers who count every gram.

Nitecore NB20000 – Maximum Capacity for Long Tours

With 20,000 mAh capacity, the NB20000 charges a smartphone up to 4–5 times. USB-C PD with up to 45 W output even allows laptop charging. Ideal for multi-day trekking tours and expeditions.

Varta LCD Power Bank – Reliable with Display

The Varta LCD Power Bank shows the current charge level on an LCD display – so you always know exactly how much energy is available. Robust construction and proven Varta quality make it a reliable companion for travel and everyday use.

Fenix E-USBC – Power Bank with Flashlight

The Fenix E-USBC combines a powerful power bank with an integrated LED flashlight. USB-C input and output, compact form factor and proven Fenix brightness make it the ideal companion for outdoor and emergencies.

Who Are Our Power Banks For?

Our power banks are designed for trekkers, travellers, commuters, photographers and anyone who needs reliable power on the go. Whether for a weekend in the mountains or a multi-week trip abroad – the right power bank keeps your devices running.

Tip: For multi-day tours, we recommend combining a Nitecore NB20000 with a foldable solar panel from our Power Generators category. The solar panel charges the power bank during the day – giving you power even after a week in the wilderness.

FAQ – Power Banks

How many times can I charge my smartphone with a 10,000 mAh power bank?

A 10,000 mAh power bank charges an average smartphone approximately 2–3 times fully. The exact number depends on the smartphone’s battery capacity and conversion losses.

What does USB-C Power Delivery mean?

USB-C Power Delivery (PD) is a charging standard that enables higher power over USB-C – up to 45 W or more. This allows fast charging not only for smartphones but also for tablets and laptops.

Can I take a power bank on a plane?

Yes, power banks may be carried in hand luggage as long as their capacity does not exceed 100 Wh (approximately 27,000 mAh at 3.7 V). All our power banks are within this limit. Power banks are not allowed in checked baggage.

Can the Fenix E-USBC charge and provide light simultaneously?

Yes, the Fenix E-USBC can use its integrated LED flashlight while simultaneously charging an external device or being charged itself. This means it is always ready as an emergency light.

Do you deliver throughout Switzerland?

Yes, fast delivery throughout Switzerland. Shipping is free for orders over CHF 100.
