I have one and it's pretty great overall except one thing. The base station auto empty vacuum is not powerful enough. It often won't fully…

Yeah, the description has many errors. I linked that particular seller because the lights I have bought from them have been good quality.…

For keyring use my favourite option is [this little LED torch for ~$10](https://www.ebay.com.au/itm/155276527176). I have bought many from…

> Im still not convinced there is any way to get this flashlight to show 1800 lumen final output without a soldering iron. Unscrew the…

Wh listed on power banks is just the cell Ah times nominal voltage, not output Wh. Nominal cell voltage is given by the manufacturer of the…

I'm not defending the manufacturers here - just saying what I've observed. I can't speak to if they are compliant with ANSI FL 1 or not, as…

Wrote more on this in another comment but @Clear is correct with the power banks comparison. Lumens is the output of the LED. Reviewers…

As far as I have seen for Wuben etc, the Lumens rating given is the LED rating at the designed peak voltage and amperage or lumen…

Because by all accounts sellers are terrible at inputting accurate specs into Amazon.

Ahhh. So you need to convert both mAh capacities into Wh to compare them. Wh = Ah x V. The phone records the mAh the battery voltage,…

Out of interest, how are you measuring the Wh output to calculate the 96% efficiency? I have tested a few of the VT103, and based on…

As far as I am aware, it only has two. So you would need to ditch the 2x8GB and install 2x16GB.

Yeah I tend to write a bit much so trimmed it when doing an update. The testing info is still in my TechRadar article. The [RG68…

I tried the same (ordering from in stock stores) and got cancelation from the actual store the first time (claiming they can't post…

A good price but note that it's 5V (12W) only so no fast charging. And charging multiple devices will be very slow.

I have a few of these but grabbed another two. Great deal! Now I just need to get around to making an adaptor that allows me to run two in…

10 hours of video playback. That's about as expected for an older i5, and a 250 nit screen (probably set to half brightness).

RRP $2,499 (hah!), discounted to $1,399, and then 20% off = $1,119.20. Sure, it's an older i5 CPU, but it's damn cheap for a pretty decent…

Yeah testing the bare cells would be ideal. I have done it on various other cells using a load tester (so it can be set to draw a constant…

Make a follow up to this video! – https://youtu.be/LK5G7c8vPcQ

Obligatory trimmer testing video. (The Ozito trimmer trimming things that should not be trimmed) https://youtu.be/LK5G7c8vPcQ My…

Ahhhh yeah ok – I don't have much experience with Nitecore gear, and previous requests for power banks have gone unanswered. Heated…

I always love an excuse to talk about this stuff! And yeah refining the testing methodology is one of my favourite bits. It's a big trade…

Nice! The phone will use a few watts when on. So 30W going into the battery means ~32W to ~34W you are getting the PPS mode for the full…

So my use of “low quality” here is being used to describe a bunch of factors that are not necessarily technically quality issues. And…

Yeah it's frustrating and there's very little accountability for false claims. And few publications actually testing power banks well. The…

Thanks! It's nice to put my power bank obsession to good use.

I had done previous freelance tech journalist work for TechRadar AU and really liked the team, so when a job opportunity came up I applied…

It depends on the laptop. Some models can charge on 12V, 9V or even 5V. But many need 20V, so wouldn't charge from this power bank.

Yep, because while I have tested a lot of Charmast power banks, none of them have been any good. I'm currently working on an updated format…
