Ordering notes
Points to confirm before production so the unit arrives ready to fit.
- Confirm the voltage and current required by the device (this DC output is 12V-1A; for devices exceeding 1A, please choose other models)
- Confirm the output interface: DC 5521 or USB (this model has both)
- Confirm whether DC double-ended cable and charging cable are needed
- Confirm the usage time required for a single charge (convert the capacity based on the time)
- Confirm whether MSDS / UN38.3 and other shipping documents need to be provided with the goods (often required for air freight / express delivery)
- Confirm quantity, packaging and printing requirements in advance.
Installation & usage
Voltage, wiring, sealing and maintenance guidance for the installer.
- After first use or long-term storage: fully charge before use; it usually takes 2-3 complete charges and discharges to achieve optimal performance
- Use designated chargers and approved accessories; do not use non-original chargers
- Charge in a ventilated place; temperature that is too high or too low will affect battery performance
- Do not power external devices while the power bank itself is charging
- Do not drop, hit, or vibrate; do not approach fire or heat sources; do not disassemble by yourself
- Avoid metal objects coming into contact with the charging and discharging sockets to prevent short circuits
- Do not modify or repair by yourself (this will void the warranty)
- When not in use for a long time, fully charge it before storing it, and recharge it regularly to avoid over-discharge damage
