The kil-a-watt meter seem good, but based on a search, they don't seem to provide access to the timeseries data, just the accumulated data. At least, it's good to know that even the sub 20 USD knockoffs work well. Sadly, it's missing a core requirement, so I wouldn't classify this as a "all you need" gadget. The functionality is quite similar to the more expensive clamp-meter I mentioned before. A minor issue I've had with knockoffs is that they often have unpredictable errors based on power draw and temperature (and sometimes, their body doesn't feel sturdy). For a personal task, your suggestion would be perfectly fine

I have a candidate: Helper's Lab USB Power Meter for USB power draw measurement. It does meet most of the requirements on paper, but I don't know how good/bad it is. Regarding AC tester, we use a clamp meter, but it has no support for any logging. It's quite cheap, about 50 USD and decently accurate. We tested some off-brand cheaper ones, but they didn't have the accuracy across different samples.

I'm looking for something handy for measuring power draw, ideally just a single device (or maybe two) for measuring: Power draw from AC socket Power draw from USB The minimal features and price range I'm hoping for are similar to netool: Easy to read logs: no unknown format, plaintext is better, but binary format with detailed specification also works Connection to configure/read data: SD Card/Wifi/BLE or even better: directly via USB Minimal display to display stats like current power usage Ergonomic size and weight (best if pocket sized like Multi-Meters) Decent accuracy (at least <2% error) and precision (3 significant digits, more if better accuracy) Range For AC power draw, support at least upto 300W sustained, ideally upto 2000W peak, 1500W sustained For USB power draw, support at least 100W, full support for USB PD 3.1 is better Time scale: configurable with averaged calculated over a period of an hour to 10ms Storage: Store at least 10 million data points (aka at least around 100MB memory) Option to either overwrite older logs or stop logging once memory is full Cost: 200-250 USD for a single solution, 180-200 USD for two (docking 20% due to lower convenience) <-- just a guideline Not all points need to be fulfilled, so I'd like you to give your suggestions even if they don't satisfy 2 or 3 points. They would be helpful to find a decent tradeoff if there's no ideal solution. PS: Personally I'd accept janky/DIY solutions, but this is not personal, so feel free to propose DIY knowing that it'd be helpful for others searching, but not for my situation

Thanks for the ThinkPad's P series. I checked it out, and some of the configuration was out of my budget. Two good options I found are: * P43s custom: 32 GB RAM, i7 8665U, Quadro P520 (2GB VRAM), 512 GB SSD, 15" UHD touchscreen * P52 stock : 16 GB RAM, i7 8750H, Quadro P1000 (4GB VRAM), 1 TB SSD, 15" UHD touchscreen A comparable System76 configuration: * Gazelle custom: 32 GB RAM, i7 10750H, GeForce 1060 (6GB VRAM), 500GB SSD (high speed), 15" HD no touch (I can replace the 500GB high speed SSD for a 1 TB 2100MBps SSD in Sys76) Are there any comparable offerings from Dell?

Any good laptops from System 76, Lenovo or Dell within 1800$ (I'm in Japan, so 200,000 JPY with shipping) with high core count and Nvidia card (for CUDA)? Main OS will be Linux, and workload will be CPU and RAM intensive (compiling code, running multi-threaded applications) with only some light gaming. I'd prefer if the battery life is 6 hours minimum under a typical load of web browsing, youtube and movie watching. Ethernet port and decent IO (SD card, 2 USB, HDMI) are cherry on top, else, an IO expansion dongle needs to be accounted for in the budget. I can go look at the offerings, but I'm assuming someone(s) here might have already taken this decision and can help reduce the number of options I have to compare.
