45W HP Laptop Charger (19.5V 2.31A) with 4.5mm x 3.0mm Blue Tip for HP EliteBook, Pavilion, ProBook & more
Product description
The essentials
A dead laptop charger is one of those annoyances that quietly ruins the day. This 45W HP laptop charger is built around the common HP power needs shown in the specs: 19.5V at 2.31A, delivering 45W output. On paper, it’s aimed at being a like-for-like replacement when your original adapter is lost, worn out, or simply no longer holds charge reliably.
What you get here is a power adapter with an output match and a specific connector size: 4.5mm x 3.0mm (blue tip). If your current HP charger matches these basics, this kind of replacement can be a straightforward fix rather than a whole new device purchase.
It’s not perfect for every situation though. If your laptop needs a different wattage, voltage, or a different plug size, this won’t be a safe bet—so it’s worth checking before you buy.
Key takeaways
The main reason people consider a charger like this is simple: getting the laptop back to usable, without overcomplicating things. The adapter input supports AC 100–240V at 50/60Hz, which is helpful if you travel or use different wall sockets, as long as your country’s plug type allows it.
On the compatibility side, the listing provides an extended set of HP model names to help you match quickly. That’s useful, but it’s also a reminder that model numbers are only part of the story—connector size and the laptop’s required power rating matter just as much.
Worth noting: it’s positioned specifically as a 45W, 19.5V (2.31A) replacement. If you’re chasing more power for a higher-spec configuration, you may feel constrained.
What really stands out
A few details in the specs make this feel practical for everyday replacement rather than a generic “works with some HPs” situation:
- Output is explicitly listed as 19.5V 2.31A (45W), which helps you verify whether it lines up with the charger your laptop expects.
- The connector size is clearly stated: 4.5mm x 3.0mm with a blue tip. For many HP power replacements, the connector is the make-or-break detail.
- Input is 100–240V, 50/60Hz, so it’s set up to handle a broader range of mains voltages.
If you’re using this for common home and office scenarios—plugging in to work, browsing, finishing assignments—this sort of 45W adapter is exactly the category you’d look for.
Still, take the compatibility list as guidance rather than a guarantee for every exact configuration. If you’re unsure, it’s safer to confirm the voltage/wattage and plug size first.
Is it a good fit for you?
It’s a good fit if you have an HP laptop (from the models listed) that uses a 45W charger at 19.5V 2.31A, and your existing adapter uses the 4.5mm x 3.0mm blue-tip connector.
It makes sense if you want a replacement adapter for day-to-day use—keeping one at home and one at work, or replacing a cable that’s seen better days.
It may not suit you if your laptop requires a different wattage/voltage, or if your original charger’s connector doesn’t match the 4.5mm x 3.0mm blue tip.
It might not be a great match if you’re trying to power a higher-draw setup and you don’t have evidence the 45W rating matches what your device expects.

What to know before buying
Before you rely on any charger listing, you’ll want to double-check three things: the output rating (19.5V 2.31A / 45W), the connector size (4.5mm x 3.0mm blue tip), and that your laptop is indeed one of the HP models referenced.
The model list is long, which is helpful for searching, but it also means it’s easy to miss the exact variant you have. If your laptop model is close but not identical, don’t assume—verify the charger requirements on the label of your current adapter (or the laptop’s documented power spec, if you can find it).
Warranty and returns
The listing states a 12-month warranty, plus a 30-day return and exchange service. That’s decent cover for a charger purchase, where faults can show up after a bit of normal use. As always, keep the receipt and packaging details until you’re confident it’s the right match.
Should you buy it?
Worth considering if you need a 45W, 19.5V 2.31A HP laptop charger and your connector is 4.5mm x 3.0mm (blue tip). With the specs clearly stated and the warranty/returns mentioned, it’s the kind of replacement that can make sense when your current adapter is no longer reliable.
You may want to skip it if you’re not confident the wattage, voltage, or connector size matches your laptop. Chargers are one of those accessories where “probably works” can quickly become “doesn’t work at all”—or worse, raises safety concerns.
If you’re shopping for a replacement mainly because you’ve misplaced your charger or the cable has deteriorated, this is the right category to look at. If you’re aiming to upgrade power for a higher-demand setup, stick to the exact power requirements instead of assuming more is better.
