I have a Dell XPS 15 laptop, and am looking for a power adapter with specific requirements. Here's what I'm after:
- Must have
- Works on XPS 15 9550 (ir-6700HQ with 1080p screen)
- Works with EU (Dutch) Type F power sockets
- Can at least support my laptop in "Balanced" power mode doing moderate development work (typically CPU usage < 50%, no big GPU usage) while not draining battery
- Can charge my laptop about from 10% to 80% when idling with screen off
In short, it should allow me to at least continue working while on power, and start charging the battery if I leave my PC in idle mode.
To further specify, I've measured how much power my laptop currently draws. It wants about 30 Watt when CPU usage is low to idling, and draws about 65 Watt at peak moments (e.g. when I'm running a few builds). Over an 8 hour day, I measured 0.20 kWh, which means about 26 Watt. These measurements were taken using a 130 Watt adapter.
- Offer Powerbank features for charging a smartphone
- As light as possible (while still offering enough power per musthaves, above)
Nice to have
- Official Dell branded hardware
- Powerbank supports QuickCharge through usb-c
Price is not too important: although I don't need a gold-plated or autographed device, I'm happy to pay a premium to get all functionalities in.
I have tried and returned the PH45W17-CA (12800 mAh usb-c powerbank with 45W adapter), as it was incompatible with my model.
For reference, charging over USB-C will not work on the 9550 with some adapters (incl the above, as well as one I borrowed from a colleague's Thinkpad), but it will work with others (e.g. some Apple chargers I borrowed in the past, as well as my WD15 Dock).
