Samsung - Super Fast Charging 45W Power Adapter - Black - Open Box - Good

Hey there Andy, thanks for your question about the Samsung Super Fast Charging 45W Power Adapter. Yes, the Samsung 45W Power Adapter (Model EP-T4511NBEGUS) will technically charge your HP OmniBook. It features USB Power Delivery (PD 3.0) and uses standard PDO/PPS voltages (including 15V and 20V) so, it can negotiate a safe power profile. Your HP OmniBook likely requires a 65W or higher charger to avoid slow charging. If you have any other questions for us or if you would like further assistance, please let us know by reaching out to Support at your leisure. Thank you for choosing Samsung! - Debra

Greetings Chuck, thanks for asking us your question about the Samsung Super Fast Charging 45W Power Adapter. Yes, the Samsung 45W Power Adapter is backward compatible with the Samsung Galaxy Note 9. However, because the Note 9 relies on older, slower charging standards, you will not get the full 45W charging speed. The power adapter uses Power Delivery 3.0 and PPS technologies, which automatically detect the connected device and supply only the amount of power it safely requires. If you have any other questions, please do not hesitate to contact Support. Thank you for being a faithful Samsung customer. - Debra
