What this adapter does and who needs it
This WAWEIS 19V 1.58A AC adapter replaces the HOIOTO ADS-40SG-19-3 19030G unit for compatible Acer LED LCD monitors and laptops. It delivers 19 volts at 1.58 amps from a 100 to 240 VAC 50/60 Hz worldwide input. Buyers who need a different voltage, higher amperage or a proprietary connector not listed here should look elsewhere.
Installation ease and common pitfalls
The adapter plugs directly into the device and mains supply with a total 10 ft power cord for flexible placement. Ensure the barrel connector matches the original ADS-40SG-19-3 specification before connecting. Forcing an incorrect tip or using the adapter outside the 100 to 240 VAC range can trigger the over-voltage, over-current or short-circuit protections and prevent charging.
Capacity headroom and limits
Rated at 19 V and 1.58 A, the unit comfortably powers supported monitors and laptops within its 40 W design envelope. It runs out of headroom when the connected device draws more current than 1.58 A or requires a voltage other than 19 V. The built-in smart chip and isolation materials maintain stable output until those electrical limits are reached.

Questions about this item
How can I confirm the adapter is delivering 19V 1.58A after I plug it in?
The unit powers on when the green LED lights and your monitor or laptop shows it is charging; a multimeter on the barrel tip should read 19 V with the supply under load.
What cables are included and is there anything else I need to buy?
The package contains the adapter brick and a 10 ft detachable AC power cord; no extra cables are required for the listed Acer models.
Which version matches the ADS-40SG-19-3 19030G label on my original charger?
This exact model replaces ADS-40SG-19-3, 19030G, ADS-40SG-19319030G and ADS40SG19319030G, so choose the one listed as ADS-40SG-19-3 19030G.
