Compatibility — which laptops does this fit?
This 150W HP charger is the OEM-spec power adapter for:
Wattage and connector are the two factors that decide compatibility. The 7.4mm × 5.0mm big barrel connector physically matches only the listed models — do not force it into a different-size port. If you have a related but different model, WhatsApp us with the exact spec sticker text and we'll confirm before you buy.
What's in the box & build quality
Every charger we ship includes the brick-to-laptop cable (fixed), the Pakistan 3-pin C5 'mickey-mouse' wall cord, and a soft pouch for travel. Build quality on this HP unit is exactly what came with the laptop new — same chassis injection, same internal magnetic shielding, same cable strain-relief.
What you get
- 1× HP 150W adapter brick
- 1× Pakistan/UK 3-pin AC cord
- 30-day check warranty card
Real-world use — what to expect
Plug it in and the laptop charges at full speed: 0-50% in about 35-45 minutes on most modern HP machines, full charge in 1.5-2 hours. The brick warms up to 40-45°C under load — that's normal for a switching power supply, not a defect. The white LED on the tip turns on the moment AC is connected, so you have instant visual confirmation the brick is alive even if the laptop battery is fully drained.
How to verify you've got the right charger
Three checks before you buy:
1. Wattage
Look at the sticker on the bottom of your current charger — if it says 150W, you're matched. A higher-wattage HP charger is also safe (laptop only draws what it needs); a lower-wattage one will run the laptop but won't charge under heavy load.
2. Connector size
Use a calliper or compare to the sample photo. 7.4mm × 5.0mm big barrel is the only fit — don't force a wrong-size pin.
3. Voltage
Must be 19.5V. Never use a HP charger from a desktop or printer — those are 12V DC and will damage the laptop board.

Frequently asked questions
What about the new USB-C version — should I switch?
If your laptop has a Thunderbolt or USB-C charging port (most HP models from 2019 onwards do), USB-C PD is the future-proof choice — you can charge from any compatible 65W+ brick, phone bank, or hub. For older slim-tip / barrel models, stick with the original-style charger listed here.
Will this 150W charger work with my HP Pavilion Gaming 15?
Yes. This adapter outputs 19.5V at 7.7A which exactly matches the HP Pavilion Gaming 15 (and all other listed models). The 7.4mm × 5.0mm big barrel connector is the OEM specification — no adapter or convertor required. Plug it in and you're charging at full speed.
Can I use a higher-wattage charger instead?
Yes, higher wattage is safe as long as the voltage matches. A 175W or 195W HP brick with the same 7.4mm × 5.0mm big barrel works fine and will not damage the laptop. The laptop only draws what it needs — extra headroom helps for fast-charge mode and heavy GPU loads.
Does the charger include the wall cable?
Yes. Every charger ships with the Pakistan 3-pin C5 (mickey-mouse) AC cable to the wall. The brick-to-laptop side is a fixed cable for slim-tip and barrel models, and a detachable USB-C cable on USB-C models.

Real customer feedback and tips
Buyers frequently tell us this charger handles hours of gaming without voltage droop. For example, on an HP Pavilion Gaming 15 running Fortnite or GTA V, the brick stays cool enough to hold comfortably — a sign of genuine HP engineering. Pair it with a UPS for uninterrupted play during power cuts. If your laptop uses USB-C, consider our USB-C PD chargers instead; but for barrel-port machines, this is the exact match. Visit the shop to test before you buy, or order through nnlaptops.com for quick delivery. Our 30-day check warranty means you can return it if it doesn't fit or fails — no questions asked.
How to identify a genuine HP charger
Counterfeit chargers are common in the market. Look for: smooth seam lines on the brick, a recessed HP logo, consistent cable thickness, and a weight of around 300g. Ours are genuine HP units sourced directly from HP Pakistan distributors. Each comes with a warranty card from N.N Laptops. If the price seems too good to be true on other sites, it's likely a fake. Stick with us for peace of mind.
