Genuine Acer 45W 19V AC Adapter
This genuine Acer power adapter delivers 45 watts at 19 volts with a 2.37 amp output. It is built for the extensive list of Acer Aspire, ES and TravelMate models shown in the compatibility data. The barrel tip measures 5.5 mm by 1.7 mm and is coloured black for quick identification. Buyers needing a higher wattage unit or a different tip size cannot use this adapter.
Sustained operation within rated limits
The adapter accepts a wide 100 to 240 volt input at 1.2 amps across 50 to 60 Hz mains supplies. It maintains the rated 19 volt and 2.37 amp output continuously while the connected laptop draws up to the full 45 watt capacity. There is no provision for short-term peak power above the stated rating. Units requiring more current than 2.37 amps will not be supported.
Fixed 19V barrel interface constraints
The 19 volt fixed output and proprietary 5.5 mm by 1.7 mm barrel connector limit use to laptops designed for this exact voltage and tip geometry. Polarity and mechanical fit must match the device charging port precisely. The adapter cannot negotiate other voltages, cannot supply power over USB-C and cannot be adapted to devices with a different centre-pin diameter or length.

Questions about this item
Does the 45W adapter run hot or make noise when powering an Aspire E5-721 all day?
The 19V 2.37A brick has no fan and no moving parts, so it stays silent and only warms to normal operating temperature under continuous load.
What must I already own for this 1.7 x 5.5mm tip charger to work?
You need a compatible Acer laptop such as the Aspire E5-721 or TravelMate P276-M that accepts a 5.5mm x 1.7mm barrel connector and requires 19V 45W input.
Will this 45W 19V unit safely replace the original ADP-45HE B on an older Aspire ES1-512?
Yes, the ADP-45HE B and PA-1450-26 part numbers are listed as direct replacements, matching the 19V 2.37A output and 1.7 x 5.5mm tip exactly.
