Questions about this item

Does the 120W adapter run hot or draw much power when left plugged in all day?

The unit includes over-heating protection with a smart chip and over-current protection, and it operates on 100-240VAC 50/60Hz world-wide input, so it stays within safe thermal limits during continuous use.

What must I already have on my laptop for this charger to work?

Your laptop must be one of the listed HP Envy 17t-j000, 17-J, 17-j001sg, 17-j003sg, E1P04AV, E1P05AV, M7-j000, m7-j010dx, m7-j020dx, 15-j051nr or 15-j059nr models so the barrel connector and voltage match.

Will this 120W supply safely charge an older HP Envy 17-J that originally shipped with a lower-wattage brick?

Yes, the adapter is 100% OEM compatible with the specified Envy 17-J series, includes over-voltage and short-circuit protection, and meets FCC, CE and RoHS certification, so it will not damage the original charging circuit.
