BIUBOTY 45W 19V DC laptop charger (compatible with selected ASUS VivoBook & ZenBook models)
Product description
What this charger is for
If you’ve ever had to swap a failing laptop adapter mid-project, you’ll know how disruptive it can be. The BIUBOTY 45W laptop charger is a replacement-style power supply aimed at specific ASUS VivoBook and ZenBook lines, using a 19V DC output. On paper, it’s designed to be a like-for-like alternative as long as your original adapter’s output and the plug size match.
It’s also worth noting that this unit is described as 45W, with compatibility mentioned for 33W 19V adapters too (so the power rating looks flexible, but only within the same 19V/connector constraints).
Key takeaways before you buy
The decision here is mostly about match, not magic. The listing provides the key requirements you should check:
- Output is specified as 19V DC at 2.37A (45W).
- The connector size is listed as 4.0 x 1.35MM.
- It advises compatibility for 33W 19V (1.75A) adapters as well.
- It includes protections such as over voltage, over current, over power, over heating, and short circuit (the listing states multiple protections, but doesn’t detail testing or certification).
What you’ll like in day-to-day use is simple: this is meant to power the laptop reliably for normal home, study, and office tasks—docs, browsing, and streaming—without you needing to run the device on battery constantly.
What matters in real life (and a limitation to keep in mind)
The biggest risk with any “compatible with” charger is getting the details slightly wrong. If your current charger differs in output voltage (DC 19V), or if the connector size isn’t the same 4.0 x 1.35MM, you can’t really make it work safely—so it’s not the kind of purchase you want to do on guesswork.
Also, the listing doesn’t describe a specific cable length or whether the plug is the exact same physical style as your original beyond the stated connector dimensions. That’s usually fine, but it’s one of those small practical details that can matter when you plug in near a desk edge or docking setup.
Where it shines
This BIUBOTY adapter is a practical pick if:
- You need a replacement charger for one of the ASUS VivoBook or ZenBook models mentioned.
- Your existing adapter is lost, damaged, or unreliable and you want a charger that meets the same core electrical requirements.
- You prefer an option that includes multiple safety protections as part of its design.
If you’re using your laptop for everyday work, having a correctly matched replacement is often more important than chasing extra features you won’t use.
Who it’s for, and who should skip it
It suits you best if you’re comfortable checking your current charger label and confirming both the 19V output and the 4.0 x 1.35MM connector size. It’s also a reasonable solution if you want a straightforward AC adapter replacement rather than exploring power banks or dock-style charging.
You may want to skip it if you can’t confirm your original charger matches the stated 19V DC output and the connector size. Similarly, if you’re replacing a charger with a different wattage and a different voltage (not just wattage), this listing doesn’t give enough to assume compatibility.

In the box and what to expect
The package is listed as including 1 x AC adapter. That usually means you’re getting the full charger unit needed for use (not just a cable), but it still helps to double-check whether your setup requires any specific accessory—particularly if you’re using a multi-device arrangement.
Buying verdict
Is it worth it?
This charger is worth considering if you match it to your laptop by the two details that actually matter: 19V DC output and the 4.0 x 1.35MM connector size. If those line up, it’s a sensible replacement-style adapter for the ASUS VivoBook and ZenBook models named in the listing.
It might not be the best choice if you’re relying on model-number compatibility alone and can’t verify the electrical and connector specifics from your original charger. For this type of product, that quick label-check is what decides whether it’s a straightforward fix—or a frustrating dead end.
Mini FAQ
How do I check compatibility quickly?
Look at your original charger label for the output voltage (should be 19V DC) and confirm the connector size matches 4.0 x 1.35MM.
Does 45W work if my laptop charger is rated 33W?
The listing explicitly mentions compatibility with 33W 19V 1.75A, so if your voltage and connector size match, it’s intended for that situation.
Is it safe to use if the wattage is different?
The listing focuses on 19V and the stated connector size. If voltage or connector size doesn’t match, you shouldn’t assume it will be safe or compatible.
What protections does it include?
The listing states over voltage, over current, over power, over heating, and short circuit protections.
What’s included in the box?
According to the listing, it includes 1 x AC adapter.
