I’ll admit I was charmed by the full-sized specs of this diminutive laptop (or netbook, as you will), and I have a thing for tiny laptops in general. So I couldn’t resist it when Banggood offered it up to me in a full-on tracking cookie assault of marketing. (That being said, I purchased it from Amazon to avoid paying duties.) It’s a solidly built little machine, and a solid performer save for one thing: It’s not what I would consider to be a gaming computer. Though it is indeed sold as one, what with it’s somewhat-included side controllers and advertising to that effect. Sure, it can play some games just fine, but without some kind of even halfway-decent (even mobile-optimized) … Continue reading
I’d been seeing a lot of different brands of rechargeable lithium ion standard-sized batteries on the market, and couldn’t decide which ones to buy. Hence, I bought many of them. Hopefully this helps you out of the same conundrum! I built a test “rig” (really just some plywood) which consisted of 5 each of milliamp-hour meters, 4-position battery packs, and 12 Ohm resistors. In all, I tested 7 brands of lithium cells, as well as 6 sets of alkaline batteries (as a point of reference for capacity), 1 set of non-rechargeable Energizer Lithiums, and 1 set of NiMH Panasonic Eneloop cells. The batteries were discharged until their aggregate voltage reached 3 (or 0.75V per cell) which I felt was a … Continue reading
The WAudio W-3900 Power Conditioner is a well-made PDU/power strip, with a couple of bucks worth of filtering components inside. If it were sold in the $50 price range, I’d definitely recommend it for its solid build quality, decent quality components, and retro looks. But at $180, the amount of power “conditioning” (it’s really just filtering certain frequencies of noise at low levels) doesn’t justify the price, IMHO. To be fair, the product can be found on AliExpress for $137 at the time of this writing. Though the marketing materials promise “the highest level of surge & spike protection”, in reality it is not what I would call a surge or spike protector. One weak PTC thermistor is presumably the … Continue reading
I purchased a Pyle PCO875 Power Sequencer simply to make a video about it, because I didn’t believe all of its claims. Though it does appear to be a somewhat-competently made power sequencer, the manufacturer’s statements about power conditioning, surge protection, spike suppression, filtering and so forth are all false. In the video I covered the Amazon listing’s specs for the device, but the specs are much the same on Pyle’s own website so it was no mistake in importing it over to Amazon. I’ll some screenshots here for posterity, because hopefully they’ll eventually correct their “mistakes”, and I want to have a record of what statements they were making at the time this video was created: I did manage … Continue reading
Another sh*tty power strip
Welp, they’ve done it again. Any by “they”, I mean people that make poor quality electrical devices. Specifically Yellow Jacket, which is a Woods brand, which is a Coleman Cable brand, which is probably somehow owned by either Warren Buffet or the Koch Brothers.
I got this for $16.22 during an Amazon lighting deal, and even though that’s not a terrible price, the poor quality construction and the basic lie about the materials is what really angers me.
Join me as I disassemble and then curse at this poor excuse for a power strip, in my newest installment of first world problems.
First World Problems I gotta start off by saying that I know that this is an extravagant waste of time and resources. I didn’t make this video because the K575 was slightly annoying, but rather because it baffles me that they became worse at designing coffee machines than before. It’s doubly confounding because Keurig has based their marketing on the K575 being a “2.0” brewer. As in a (supposedly) new-and-improved follow-up to their original line. Yes, it has a couple of advantages over the older B70 Platinum that I used for comparison. However, it seems that they increased the features without increasing the cost. That says to me that they designed these new brewers on a budget. A schizophrenic software … Continue reading
Oshkoshbegosh!? Another long ramble about power distribution thingies for the home and/or office?!
Well it’s true. Hopefully my next video will not be about this subject.
This compares the relatively-generically-branded Belkin Advanced Surge Protector (which actually bears the handy model number of BE112230-08, like it came out of some kind of dystopian nightmare) to the easily-spoken Furman SS-6B (which itself sounds shockingly dystopian anyway).
I was searching for an “affordable” power distribution unit for some video-related equipment in a rack. The Technical Pro PS9U looked very appealing with its multiple light-up switches on the front, because they made me all sentimental and wistful for the days of switched under-monitor PDUs.
It took a dark turn when I looked at the negative reviews on Amazon, wherein one person uploaded pictures of a melted-down unit. I still bought the PDU, not because I wanted to use it, but purely because I wanted to take it apart for YouTube.
And indeed the Amazon review turned out to be accurate. I would not feel comfortable using the Technical Pro PDU in my house. In my opinion as a random guy on the internet, it is a fire hazard, is poorly made, and shouldn’t even be on the market.
For my actual use, I also bought a Cyberpower CPS-1220RMS PDU. It’s a bit different than the Technical Pro in that it doesn’t have independently-switched outputs, offers surge protection, and is rated at 20A rather than 15A (though “rated” is a strong word in the case of the PS9U). That’s just on the surface, though. Inside, the Cyberpower shows every mark of quality and clearly supports its 20A rating.
In the video I open up the Cyberpower, just to show you what a quality PDU should look like. The comparison between the two products is day and night, even though I got the Cyberpower unit for a mere $15 more (on sale). It’s absolutely worth the higher price (even when not on sale).
The bottom line here is that when it comes to power distribution — be it rack-mounted or a typical power strip style — you should spend the extra money to get the higher-quality unit. Your fire insurance provider will thank you, as might your family (if it comes to that).
This is a follow-up of sorts to my NiMH Battery Roundup video, except this time I’m looking at triple-As, and only one brand.
I was vexed by the fact that Amazon had EBL AAA cells with an 1100mAh capacity for only 7 cents more per cell than the otherwise-identical 800mAh variety. That didn’t make sense to me, and besides, 1100mAh is rather high for a AAA package size. Hence I bought a bunch of each and tested them.
The Bottom Line
The 1100mAh cells appear to be a big fat lie. The average capacity for those clocked in at 980mAh, with one cell showing as low as 946mAh and the highest at 1005mAh.
The 800mAh cells were respectable at an average of 809mAh, and less of a variance between cells.
Despite the fact that the “1100mAh” units were well under capacity, they are of course the better deal coming in at 852mAh per dollar with the 800mAh cells giving 749mAh per dollar.
I wish I had the time, inclination, or money to pit a whole bunch of AAA brands against each other, but I’m satisfied in imagining that quality scales from my AA cell results.
