Product details

The power bank comes with two permanently installed 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 needed. The second cable is ideal for reliably powering smaller devices like TWS headphones or your smartwatch. You can charge a tablet or a second smartphone simultaneously via the additional USB-C port, while the USB-A port easily supplies power to older devices or accessories like speakers or cameras. This way, you always have the right solution at hand - without additional cable clutter. This power bank is pass-through capable: it charges itself and your smartphone or tablet simultaneously. So you no longer have to decide which device gets power first. Especially practical in the evening on your bedside table or on the go on the train - one cable is enough, and all devices are supplied at the same time. The integrated LCD display shows you the charge level in percent. Instead of guessing how much energy is left, you know at a glance. This way, you plan your next charge in good time and always have full control over your mobile energy. With a weight of only 321 g and handy 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 a big trip. So you always have strong energy with you, without having to carry additional weight or bulky accessories.
