![]() I was pleased to see this power pack charge my Spectre without issue and even kept increasing the battery percentage while under heavy system loads like video editing, gaming, and synthetic benchmarking. My HP Spectre comes with a larger AC Adapter (90w) as it has a dedicated GPU and Quadcore Processor. My Lenovo ThinkPad uses a 65w AC Adapter, and took a charge from this unit without issues. ![]() There are also marking on the rubber showing the functions of the various ports. The top is a faceted matte plastic and the bottom has a rubberized foot so it won’t slide around. USB C - 60w Output / 45w Input (Power Delivery Spec for more wattage hungry devices).This cable supports at least 60w, but is limited to USB 2.0 speeds. The unit comes with a nice carry pouch, and a USB C to USB C cable with one end at a 90 degree angle. The look and feel of the power pack is top notch, as would be expected from a “Spectre” accessory which in my opinion are the best looking laptops on the market right now. I have 2 laptops that I tested this with, 1) HP Spectre x360 15t w/ Dedicated GPU, 2) Lenovo T570 ThinkPad 15.6in. HP Spectre USB-C 20100mAh Laptop Battery Power Pack - $139 (as of 12/20178) Here is a link to this product if you would like to give it a try. This is not the first "Laptop" capable Power Pack I have tried, and up until now the ones I have tested have been a disappointment. So it will drain the battery faster and shouldnt be switched on for too long.I have been looking at a battery pack for my laptop to use while traveling on work trips, and with this unit advertising 20,100mAh and 60w charging rate via USB-C (Power Delivery Spec), I decided to give it a try. That tool is good for taking a peek, but it will task the cpu up to 10% constantly. The tool I use there is called sidebar diagnostics, you get it as FOSS on Github. CPU Temperature is pretty chill and the dGPU is switched off. I have Teams and the Citrix Receiver running but work 90% of the time on the laptop, so its not idling. The cpu has 3 cores parked here and it will park up to 4 if nothing is going on. And I have the max charge limited to 90% in the BIOS to protect the battery a bit: Here is a picture at roughly 75% battery time last, there are 7 hours and 11 minutes remaining. That should be overall be more efficient. On the other hand, if you just limit frequency, you will prevent it from going into high power consumption states, but its still able to spike for moments in bus frequency and ram frequency to get the job done fast and then go back to sleep. If you limit other stuff, the cpu will be forced to run longer to complete a task and to draw a constant amount of current. I would not limit anything for this cpu, except the max frequency. The cpu is very sensitive, you should check if you have a cpu-intensive app running in the task manager that constantly needs the cpu to be going. If the programs are closed and I am just reading a website or a pdf in tablet mode, it goes up to 10 h tops. With that setup, I get a good 8 - 9 hours. ![]() I have MSTeams and Citrix Receiver running for my work but I mainly use the browser, mail tool and writer on the laptop. Then I switch to energy saving at 1,3 Ghz and have up to 8 threads parked, if nothing is going on. Basically when I start to work, I go to the normal performance power plan, which I limited to 2,6 ghz and fire my programs up. I got me the tool power plan switcher and can change between plans quickly from the system taskbar. But there is more, you can set the aspm power states of the wifi, so you wont have full bandwith but it will consume way less energy. If you reenable the energy saving plans, all this settings will come back and there is an option to set the parking of cores. It comes with 6 cores and 12 threads, so it will park 8 threads and 4 cores.
