Errbbic S1008D Solar Power Bank Features and Specifications

Errbbic S1008D 20000 mAh Solar Power Bank comes with a 20000 mAh (20 Ah) internal battery being able to store ~74 Wh of energy, which is enough to recharge iPhone X or Galaxy S9 Plus 5 times.

The unit has rugged construction with increased protection from water, dust, and mechanical impacts.

According to the manufacturer, Errbbic S1008D Power Bank features IPX4 waterproof level - unit is resistant to splashing water from any direction for 10 (ten) minutes, which makes the unit suitable for camping, hiking, fishing, and other outdoors activities.

Note: Errbbic S1008D Power Bank should NOT be submerged underwater!

Errbbic S1008D Power Bank features two USB charging ports, 5.0V/2.1 Amps USB and 5.0V/1.0 Amps USB charging ports.

Note: Errbbic S1008D Power Bank features a maximum output current of 2.1 Amps, so if the 5V/1.0 Amps port is used for charging, 5V/2.1 Amps port can deliver only ~1 Amps!

The third port is used for recharging the internal battery via a wall USB charger or using a laptop/desktop USB port.

Errbbic S1008D Power Bank features a 2W solar panel that allows the user to recharge the internal battery while being completely off-the-grid.

However, this is a 2W solar panel - considering the size and weight of the unit, it can't be any larger!

Under almost ideal conditions, it takes a 2W solar panel 5-7 days(!) to recharge the internal battery completely - enough to recharge iPhone X/Samsung S9 Plus on a daily basis almost fully.

So, it is highly recommended to recharge the battery using a wall USB charger or computer's USB port, especially when the battery is brand new (the first 3-4 recharges should be done using USB chargers and NOT the built-in solar charger).

If You need more energy while being off-the-grid, consider getting a portable foldable solar USB charger.

Such solar USB chargers feature larger surfaces and are able to collect more sunlight.

Additional features of Errbbic S1008D Power Bank include a small magnetic compass and a flashlight consisting of a pair of LEDs.

The LED flashlight features several light modes including constant light, SOS, and strobe and it can come in very handy in many situations, just be sure not to discharge the battery too much, of course.

Errbbic S1008D comes with 5 control LEDs including 1 green LED to signal the solar charging and 4 blue LEDs to indicate the remaining battery charge.

What's in the Box?

When the unit arrives, the box contains one Errbbic 20000mah Solar Charger, one USB cable, a manual, and the D-Ring.

Although Errbbic S1008D is easy to use, when it arrives be sure to read the manual, just in case.
