With the 20,000 mAh HEAD Trek solar power bank, you can keep all your gear running during hikes, camping trips and multi-day adventures, with enough capacity to provide up to four full smartphone charges, depending on the model. Its five fold-out solar panels use the available sunlight to recover energy when you are far from a power socket, while 22 W Power Delivery lets you charge smartphones, tablets and other compatible devices quickly. You can also use the wireless charging surface whenever you would rather go without a cable. Its reinforced construction, with IP54 protection, is designed to handle dust, splashes and the demands of outdoor use. The display shows the remaining battery level, while the built-in torch provides light after dark.
Up to 4 charges in reserve
With 20,000 mAh, you can spend longer away from a power socket while keeping the devices you rely on during your trip up and running. Trek provides up to four full smartphone charges, depending on the model, and its large capacity lets you share the available power between your phone, GPS watch, camera, earphones and other gear without using up the entire reserve in a single charge.
Unfold. Recharge. Keep going.
Trek features five solar panels that expand the charging surface when unfolded, helping make better use of the available sunlight. This solar input helps maintain the power bank’s charge during hikes, getaways and outdoor activities. When not in use, the panels fold neatly back onto the power bank itself to take up as little space as possible in your backpack. Solar charging performance depends on light intensity, panel orientation and environmental conditions.
Wired or wireless
When you need to recharge quickly, the 22 W Power Delivery USB-C port can power the devices you are likely to take on an outdoor trip, such as a smartphone, action camera, hiking GPS or rechargeable torch. The USB-A port gives you more options for other accessories, and if you would rather go cable-free, simply place your smartphone on the wireless charging surface.
Built for the outdoors
Its reinforced construction, with rubberised edges that help absorb minor knocks and scrapes, is designed for outdoor use. IP54 protection helps guard against dust and splashes, while the built-in torch is useful for lighting the way, checking your equipment or moving around the campsite after dark. A tougher design for when the route gets more demanding.
Know how much power you have left
The digital display lets you see the exact remaining battery percentage at a glance, helping you manage your energy more effectively while you are out. You will know when it is worth unfolding the solar panels, which devices to charge first and how much power remains before heading even further away from a mains supply.
