Technical overview

Supports 6–24 V solar panels; input via DC-002 jack or screw terminal.
Embedded 3.7 V 10000 mAh Li-Po battery; also a 14500 battery holder and PH2.0 connector for external 3.7 V Li-ion batteries.
Two 5 V outputs: pin header and USB port.
Onboard MPPT SET switch selects the input level setting to improve charging efficiency.
Multiple LEDs indicate battery capacity (LED1–LED4 depending on charge level).
Protection circuits guard against overcharge, over-discharge, reverse connection, overheating and overcurrent.
Operating temperature range: −40 °C to 85 °C.
Dimensions: 108.0 × 71.0 × 25.2 mm.
Fast-charge mode over TYPE-C only works if the power adapter supports fast charging.
Can be used to power SBCs such as Raspberry Pi, Jetson Nano or Arduino.

Commands and examples – verify before use:

Schalter einschalten und BOOT-Taste drücken, damit die LEDs den Ladestand anzeigen.
Solarmodul an DC-002-Buchse oder Schraubklemme anschließen; bei korrekter Verbindung leuchtet die „Solar Charger“-Anzeige, bei Umgekehrter Polung die „Solar Warning“-Anzeige.
Netzteil am TYPE-C-Anschluss anschließen; die Quick-LED zeigt den Schnelllademodus an, falls das Netzteil dies unterstützt.
Bei Änderung der Solareingangsspannung (z. B. auf 18 V): Gehäuse öffnen und DIP-Schalter auf der PCBA entsprechend einstellen.

Notes and version constraints

Lithium batteries can cause fire, injury or property damage if misused; never place non-rechargeable cells in the holder.
Incorrect polarity or an unsuitable charger creates explosion risk.
Connecting multiple solar panels is not recommended; the charging current is limited to 2 A and total power should stay below 10 W.
Charging times depend heavily on environmental conditions; quoted values are from constant-voltage lab tests.
Changing the DIP switch requires opening the case and is version-sensitive – have the manufacturer confirm before proceeding.
