Sandberg® Solar 6-Panel Powerbank 20,000 mAh

Description

Sandberg® Solar 6-Panel Powerbank 20,000 mAh – independent energy anywhere

The Sandberg® Solar 6-Panel Powerbank combines a large 20,000 mAh capacity, a foldable solar panel, and versatile charging options. It is a practical energy source for hiking, camping, road trips, summer houses, festivals, or your home emergency kit.

When the grid or a wall outlet isn’t available, you can charge the power bank using the six-part solar panel. The larger solar surface collects light more efficiently than power banks with small integrated panels, allowing you to maintain your energy supply even during extended stays in nature.

According to the manufacturer, the 20,000 mAh (74 Wh) capacity is enough to charge a typical smartphone up to eight times. The actual number of charges depends on the device’s battery size, charging loss, the cable used, and the ambient temperature.

Foldable 7.5 W solar panel

The biggest advantage of this 6-panel power bank is the foldable six-part solar panel. The panel can be opened into a large light-collecting surface and, if necessary, detached from the power bank.

The set includes a carabiner to attach the power bank or solar panel to, for example:

• a backpack;
• a tent or canopy;
• a camper or caravan;
• a sunny spot at the campsite.

The solar panel output is up to 7.5 W. The manufacturer’s stated solar charging time is approximately 12 hours, but actual speed depends on sunlight intensity, panel position, cloud cover, season, and temperature. For best results, point the panel directly at the sun and avoid shadows.

Solar charging is primarily suitable for topping up energy reserves away from the grid and for emergencies. Before a long hike or trip, it’s recommended to fully charge the power bank via USB cable and use the solar panel to restore energy along the way.

20 W USB-C PD fast charging

The Sandberg® Solar 6-Panel Powerbank supports USB Power Delivery (USB-C PD) fast charging with up to 20 W. Using a suitable device and cable, you can charge compatible smartphones and other USB-C devices faster than with standard USB charging.

The power bank has a total of three outputs:

• 1 × USB-C PD output up to 20 W;
• 2 × USB-A outputs up to 18 W.

You can connect up to three devices simultaneously. This allows you to charge, for example, a phone, GPS device, headlamp, sports watch, wireless headphones, or other USB-powered camping gear.

The USB-C port can be used for both charging the power bank and charging other devices. Additionally, the power bank has a Micro-USB input.

Suitable for hiking, travel, and emergency kits

The 6-panel solar power bank is an excellent choice for situations where access to the power grid may be limited or completely unavailable.

It is well-suited for:

• hiking and camping;
• extended stays in nature;
• car, boat, and caravan trips;
• festivals and outdoor events;
• fishing and hunting;
• summer houses or country homes;
• home emergency and power outage supplies.

The power bank features a built-in flashlight for use in tents, on dark trails, during power outages, or as emergency lighting.

The IPX4 rating means the device can withstand water splashes from various directions. This makes it suitable for normal outdoor use, but the device must not be submerged in water or left in heavy rain for long periods.

Power-through charging

The power bank supports power-through functionality. This means you can charge the power bank while it is simultaneously charging a connected device.

This feature can be useful when using the solar panel or when only one charging source is available. Charging speed may decrease when multiple devices are connected or in power-through mode.
