All about the product
Load more, wait lessThe power bank comes with two permanently attached USB-C cables, an additional USB-C port, and a USB-A port. The primary cable with up to 22.5 W is perfect for fast charging your smartphone and can even charge the power bank itself if necessary. The second cable is ideal for reliably powering smaller devices such as TWS headphones or your smartwatch. The additional USB-C port allows you to charge a tablet or a second smartphone at the same time, while the USB-A port also easily supplies power to older devices or accessories such as speakers or cameras. This means you always have the right solution at hand – without any additional cable clutter.
Energy in both directions
This power bank is pass-through capable: it charges itself and your smartphone or tablet at the same time. So you no longer have to decide which device gets power first. Particularly handy in the evening on your bedside table or on the train—one cable is all you need to charge all your devices at the same time.
Control at the touch of a button
The integrated LCD display shows you the charge level as a percentage. Instead of guessing how much energy is left, you can see it at a glance. This allows you to plan your next charge in good time and have full control over your mobile energy at all times.
Performance without ballast
Weighing just 321 g and measuring a compact 10 × 7 × 2.5 cm, this power bank is one of the lightest and most compact in its class. It fits easily into any bag and can accompany you everywhere—from your daily commute to long journeys. This means you always have plenty of power with you without having to carry any extra weight or bulky accessories.
