Barnes and Noble Recalls 147,000 NOOK Tablet 7 Power Adapters Due To Shock Risk (betanews.com)
BrianFagioli quotes a report from BetaNews: Want to know something shocking? Like, literally shocking? Barnes and Noble is recalling 147,000 faulty NOOK Tablet 7 power adapters due to shock risk. In other words, owners of this tablet could face an electricity related injury when charging it. If you own this tablet, it is important that you stop using the charger immediately. While there is no guarantee that you will be injured, it is not worth the risk. Barnes and Noble will replace the power adapter at no charge. To make up for the inconvenience, the company will also give you a free gift. "Consumers should immediately stop using the recalled power adapters and register online for a free replacement adapter along with a Barnes and Noble $5 gift card. Once registered, consumers will be able to print a pre-paid UPS label to return the recalled adapters to Barnes and Noble. Consumers will receive replacement adapters in the mail. Until a replacement adapter is received, consumers are advised to charge their NOOK Tablet 7 through their computer using a USB cable," says Barnes and Noble. The book-seller also says, "This recall involves the black power adapter sold with the NOOK Tablet 7. The adapter bears markings: model number TPA-95A050100UU, manufacture date 201610. The NOOK Tablet 7 model number BNTV450 is located on the back of the NOOK. Barnes and Noble has received four reports of the power adapter breaking or pulling apart exposing the metal prongs. No injuries have been reported." If you are affected by this recall, you can visit this site and follow the instructions.
SHOCKING!
I mean, power adapters falling apart? Somebody obviously squeezed another cent out of the $0.05 housing, making it impossible to produce quality.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
instead dumb electricity
its not going to work
Equipment designed to electrocute the owner should then self destroy by battery explosion, so that no evidence is left to investigators.
When I was working in an electronics OEM, I witnessed such tendency: the bigger and more reputable the buyer brand is, the more hellbent they are on the most ridiculous cost saving measures.
Conversations like one below was happening pretty much with all an every American buyer
"-how thin can you make the plastic on this part?
- 0.8mm but I would really would not recommend that...
- guy interrupts, "can you make it thinner than 0.8?"
- yes, but...
- Amazon idiot interrupts again, "how much will it save us per piece?"
That was a sourcing project for the first Amazon ebook reader wallwart. We also did the cover and sleeve cases for them.
We did things that were to bigger extent more stupid than bad on extent of material scale: putting diodes in parallel, doing wire fuses, using leds in a diode role, making cases out of PLA or even crappier plastics, intentionally using recycled li-ion cells, aluminium wiring and stuff like that... All on explicit demand of a customer.
The biggest ever saving any client had through any of those measures was 6.36 US cents per piece.
huh?
Still waiting for the recall of their power adaptors. They shock up to 90V: https://www.youtube.com/watch?t=1&v=3n1U1ZJNBt8
How about getting rid of the ADUPS spyware, once and for all, while they are at it?

Seriously, they know I bought one of the devices. Why do I need to take my time to package the thing and send it back.
Just send me a replacement. The SN of the unit is registered and you have to provide that to get the replacement.
But they want me to print out a shipping label, package the old defective DO NOT USE one back.
I bought one of these at launch, as I was looking for a cheap Android tablet that wasn't total garbage. Since B&N seems to be willing to take a hit or sell it at break-even in order to promote their Nook ecosystem, it's actually a really good tablet considering the price. It's basically a stock Android 6.0 tablet with Nook apps installed and Google Play, unlike Amazon's entry which is stuck with FireOS.
That said, to be clear, this is basically a relabeled off-brand tablet. In adb it shows up as "Southerntelecom". I'm willing to bet this same basic tablet is available for a few dollars more without the Nook logo on the back.
All of this to say that it's maybe less likely that B&N wanted to pinch pennies on the charger and more that the charger was a cheap POS to begin with because the whole gimmick with this tablet is that it's cheap. It may be why that issue with ADUPS showed up a while back (they have since patched it out). B&N sells cases for it at $22.99, nearly half the cost of the tablet itself.

Saving material is green. Whether plastic or metal, less energy has to be spent on extraction, processing, transportation, and less trash is generated. Using lower quality materials wherever possible is also green.
Lowering costs creates wealth (higher purchasing power) and should be encouraged as long as it is does not endanger lives.
Diodes in parallel is conceptually bad because they do not share current evenly. However, if a 80%/20% current sharing is sufficient to get you the design margin after allowing for manufacturing tolerances, you've solved a problem cheaply.
LEDs in a diode role sounds strange but if it solves the problem, why not? I admire the ingenuity.
Crappier plastics sound bad, but it is an aesthetic issue or a durability issue? Sometimes, I've used the same plastic everywhere because it saved me time. This was a good approach when the engineering time dominated the total cost (NRE + material cost * units sold). As the quantities increased, more engineering effort to reduce costs was worthwhile. If we can save 100M people $6.36, we have added $636M to the economy.
Wire or trace fuses should be okay as long as there is a control to test them (you can test the resistance and figure out if it sized right) in the production line. If the likelihood of failure is small, there is no point burdening everyone with a cost of recovering from something that will happen to say .01% of the population, especially if you're not managing line voltage.
Recycled li-ion cells sound bad, but if you don't need 100% of the capacity and are going to charge them slowly and they can be certified to be safe through some process, then why not? Why create more junk on the planet when the specs don't demand it?
Aluminum wiring - again, if you don't need the high current, why spend more energy to extract copper when aluminum is more abundant?
And yes, people should get bonuses if they save money. If you figure out a way to save everyone $10 because you are going to make 1% of that, more power to you, especially if that comes from conservation (cheaper materials, more abundant materials, easily extracted materials, excess capacity components). If you're cheating physics - more power to you! I only have a problem with it if you're cheating people.
You mean BN sends my new hardback by UPS Sure Post, but will pay UPS rates to send a worthless charger back to them?!?
quite Shocking!
