Both chargers output up to 45W over USB-C PD, but they're optimized for different phones. The Google 45W charger uses PD 3.1 with PPS tuned for Pixel devices, while the Samsung 45W charger uses PD PPS tuned for Samsung's Super Fast Charging 2.0. Either will charge any USB-C phone — but pairing the matching brand gets you the fastest, most predictable result.
Quick Comparison

| Protocol | USB PD 3.1 with PPS | USB PD with PPS (Super Fast Charging 2.0) |
| Best paired with | Pixel phones, Pixel Tablet, Chromebooks | Galaxy S/Note series supporting 45W |
| Plug Type | EU two-pin | EU two-pin |
| Cable Included | No | No |
| Origin | Made in Vietnam (genuine Google) | Genuine Samsung |
Will a Samsung Charger Slow Down My Pixel?
Not dangerously — but it may not hit peak speed. Pixel phones are tested and tuned against Google's own PPS charger profile. A Samsung charger will still deliver PD power the Pixel can use, but the fine-grained voltage steps that unlock the very top of the charging curve are calibrated by Google specifically for its own hardware.
The reverse is also true: a Google charger will charge a Samsung Galaxy phone, but won't guarantee Samsung's fastest "Super Fast Charging 2.0" curve.
Practical Takeaway for Pakistani Buyers
- Own a Pixel? Get the Google 45W charger — it's built for your device.
- Own a Galaxy phone? Get the Samsung 45W adapter instead.
- Own both, or share chargers at home? Either charger works across both phones safely — you're only trading a small amount of peak speed, not risking the device.
- Buying for a Chromebook or tablet? The Google 45W charger has the edge, since Chromebooks are commonly tested against Google's own charger specs.
FAQs
Can I use a Samsung charger on a Google Pixel safely?
Yes. USB-C PD is a universal standard, so the charger and phone will simply negotiate a safe power level even without brand matching.
Which charger charges faster — Google or Samsung 45W?
On their respective matched phones, both reach similarly fast speeds. Cross-pairing them (Samsung charger on Pixel, or vice versa) typically charges slightly slower than the brand-matched combination.
Do both chargers work with Pakistani wall sockets?
Yes, both the Google 45W and Samsung 45W chargers use an EU two-pin plug that fits Pakistani sockets without an adapter.
