    Re: HP Powerup Backpack can recharge your laptop

    I know power banks are currently a popular thing that shops give away for free with every purchase over xx bucks, but isn't charging a battery with a battery super inefficient? Lithium batteries are super cheap right now and will probably get even cheaper, but if we waste our resources for this kind of stuff, we are gonna suffer in the future.

    Not for a while yet though (lithium at least should outlast oil, not sure about cobalt) and the batteries are recyclable though the process is a little dangerous. I'm more concerned with how many of them are cheap junk. Those cells that provide 20% of their rated capacity are junk, those chargers that're less than 80% efficient are junk, the ones that provide power way out of spec and damage devices are junk. It's only going to get worse as manufacturers try to resist passing the increased cost of smart circuitry to handle USB-C connections on to the consumer.

    Indeed - you get about 40% energy waste doing it this way. But on the other hand, the compulsive craze for manufacturers to get rid of removable batteries have kinda forced this on us.

    Wouldn't it just be easier to carry a spare battery for your device?

    Probably, but a lot of devices don't have replaceable batteries any more, and in the case of laptops it does have the advantage of not having to power off to switch cells, which is something.

    Shame it looks like.. that.

    All these batteries in luggage is worrying me a bit. I've seen suitcases with wheels and motorised systems being advertised so you can ride on your luggage around airports. Surely bringing all these batteries on board is a fire risk? I mean just look at the hoverboard battery and ee powerblock fire issues what happens if they had been in an aircrafts luggage at the time of fire. These same batteries might be part of your luggage in the future which is worrying.

    It was, until manufacturers starting making it impossible. Been complaining about the same with phones for years.

    Lenovo has a solution for that which still allows you to switch batteries without powering off, and have had it for years...

    No, you've not seen suitcases with wheels and motorised systems being advertised so you can ride on your luggage around airports. The ads specifically don't include any shots of airports, because they're banned and cannot be taken on aircraft.

    As for fire risks, well yes, of course, that's why batteries on planes are already heavily regulated. Hoverboards and EE powerbars aren't allowed in aircraft holds. There are also strict limits on the size, type, and number of batteries that can be brought onto planes in carry-ons and these rules have been around for years. While some people ignore the rules, security are trained to spot these in your bag during X-rays and will remove them from you if you are seen taking the piss.

    Then again, back in the old days you could smoke on planes, and lighters were allowed...

    Because all the stupid consumers keep buying devices with non-replaceable batteries! I insist on sticking to my LG G3 as a matter of principle.

    Out of interest, have you bought a spare battery for it?

    (My wife has a G3, and we haven't bothered yet though it was a thought in the buying process)

    Jeez, and I thought walking around with a back-breakingly heavy backpack full of battery was a thing of my distant Army radio operator past...

    All Li-ion batteries wear out, mine was no exception, so of course its on its 2nd battery already! All phone users will spot the 1st sign - when the phone does not last as long. Then the phone will power off or reboot when the battery is nowhere near 0%.

    Of course, it helps to have a rooted phone where you always know it is not software related battery drain (Greenify+Amplify+Power Nap, Titanium Backup freezing unnecessary stuff).

    What has powering off to switch cells have anything to do with it? Irrelevant!
    If you buy something without removable batteries, you have nothing to switch!

    This is even more about consumers being stupid enough to buy phones with non-removable batteries in the first place.

    If you all had boycotted the fruit phone, boycotted Samsung when they removed that feature, it would not have happened. Eg. When Samsung removed the micro-SD card slot, sales tanked immediately and they had to restore it in the next phone.

    That is what consumers should be doing - by voting with their wallet and hurting manufacturers when they do stupid things.

    Re: HP Powerup Backpack can recharge your laptop

    I think the only phone I have ever replaced the battery on was an HTC One-X, where you aren't supposed to be able to replace the battery. It can be done, there are usually youtube videos saying exactly how to do it, it just isn't trivial.

    Replaceable batteries was a part of buying the LG G3 though.
