So, I’ve ordered the 2026 Razer Blade 16 5090 ( https://www.razer.com/gaming-laptops/razer-blade-16/RZ09-05819EN9-R3U1 ). The specs show the charger for it is “280 W AC Adapter, Output: 20 V DC, 12.5 A, 250 W, Input: 100-240 V AC, 50 / 60 Hz universal”.
I currently have (1) a 2023 Razer Blade 16 4090 and (2) a 2020 Razer Blade 17 2080 Super that are used between 2 users between 3 desks and a travel briefcase from the office. (I keep a spare of the 280w 19.5v from the 2020 Blade 17 in another bag when both need to be out and about). To handle both laptops at every location, I have 4 of the 330w chargers that were OEM for the 2023 Razer. Those 4 chargers are 19.5V 16.92A, Model #RC30-0484. They are the same voltage as the OEM for the 2020 power supply - so I’ve been able to setup the three desks and my laptop briefcase to just carry the 330w to cover using either of the 2023 or 2020 models.
Now, I’m faced with either (a) buying 3 more chargers for the 2026 Blade 16 and keeping BOTH chargers on each desk and either keeping a separate laptop briefcase or switching out the chargers depending on which laptop goes or (b) resolving that the difference between 19.5 v (on the 330w charger) is sufficiently close to the spec on the 2026 Razer Blade 16 5090 (whose charger is 20v 12.5a) such that it can use the 330 w chargers I already have. Additionally, the users would need to be careful to select the right charger plug on each desk when using them.
The amperage and total wattage on the 330w chargers is far more than sufficient - the challenge is whether the 19.5 v provided to the 2026 Blade 16 will be a problem - either initially or over the long term.
I’ve read that chargers often operate within a range around their spec anyway - so perhaps the laptop is setup to handle this much variance without any added wear and perhaps the charger is setup to handle this much variance without any added wear.
I haven’t been able to get an answer clear enough for me to risk delicate and expensive electronics yet. Can anyone help me with an answer? Could Razer get an engineer from their team to help me here?
