LG LM40 Power Adapter
When choosing a new charger, choosing the LG brand one is the best one to choose. The LG LM40 power adapter is needed for two reasons, charging the battery and to provide a source of power for the unit. If buying off-brand, make sure to check both the volts and amps outputs. A universal AC adapter is a possibility if you are desperate. Because LG uses one power charger that powers multiple other machines, make sure you check the part number for the correct one.
Major clues the power charger will not last the year
- The unit will not operate without the battery installed
- Battery does not charge up whatsoever
- Most LG adapters get warm when they are plugged in for a period of time
