More charging, less waiting
The power bank comes with two built-in USB-C cables, an additional USB-C port, and a USB-A port. The primary cable, with a power output of up to 22.5 W, is perfect for quickly charging your smartphone and can even recharge the power bank itself if needed. The second cable is ideal for reliably powering smaller devices like TWS earbuds or your smartwatch. With the additional USB-C port, you can charge a tablet or a second smartphone simultaneously, while the USB-A port easily powers older devices or accessories like speakers or cameras. This way, you always have the right solution at hand – without any extra cable chaos.
Energy in both directions
This power bank is pass-through capable: it charges itself while simultaneously charging your smartphone or tablet. This means you no longer have to choose which device gets power first. It's especially convenient at night on your bedside table or while traveling on a train – one cable is enough, and all devices are powered at the same time.
Control at the push of a button
The integrated LCD display shows you the battery level in percentage. Instead of guessing how much energy is left, you can see it at a glance. This way, you can plan your next charge in advance and always have full control over your mobile energy.
Power without bulk
Weighing only 321 g and with compact dimensions of 10 × 7 × 2.5 cm, this power bank is one of the lightest and most compact in its class. It fits effortlessly into any bag and accompanies you everywhere – from your daily commute to your big trips. This way, you always have strong energy on hand without having to carry extra weight or bulky accessories.
