- measurement of actual output power, voltage, current on each port under load
- thermal imaging of heating zones (inverter, battery, controller, connectors)
- checking fan operation, thermal sensors, cooling system
- measuring standby leakage current
- diagnostics of BMS condition and cell balancing
- checking inverter, charge controller, MPPT (for solar models)
- disassembly for access to internal contacts, boards, and fans
- ultrasonic cleaning of boards, internal connectors, buttons from oxidation and dust
- mechanical and chemical cleaning of fans, heatsinks, air ducts
- cleaning of all accessible internal contacts (battery connectors, boards, ports)
- treatment of contacts with specialized cleaner and protective lubricant
- checking connector tightness and absence of play
- full testing after cleaning: charging, discharging, all ports, fans under load
- issuing a detailed report: detected issues, repair/exploitation recommendations
The service is performed for all popular models of portable power stations.
When Comprehensive Diagnostics with Contact Cleaning Is Needed
The service is especially relevant in these situations:
- power station intermittently drops out under load or individual ports stop working
- poor or unstable contact in charging/output connectors
- crackling, clicking, whistling sounds during operation or fans run too loud/do not start
- station gets very hot in connector, inverter, or fan areas
- issues appeared after transportation, storage in dust/moisture/cold
- output power lower than rated or drops when multiple devices connected
- station sat unused for a long time (over 6–12 months)
- used in dusty, humid, or smoky environments
- after poor-quality home cleaning or use of unsuitable agents
- want to maximize battery and electronics lifespan
- planning long-term use (backup power, travel, cottage) and need confidence in reliability
Cleaning contacts and fans often resolves 60–80% of minor to moderate issues without needing expensive component replacement.
