To note, that it's 7.62V (i.e., 2S), so it's equivalent to most ~3000mAh packs. Still not great for the money, but not as bad as it sounds.

- skavi 5y agoWhy did the mobile industry decide to use mAh instead of Wh.
- stevenpetryk 5y agoI think that's just the battery industry. Whenever I shop for batteries for robotics or RC vehicles they're in mAh too.
- foobarian 5y agoMaybe it's slightly more convenient because the same value applies no matter how many cells are in the battery pack. So it helps distinguish the packs by electrical current output capacity which we can't get from a power value because power combines two different measures.
- notatoad 5y agomAh doesn't change as you add cells to the battery pack? i'm pretty sure that's not correct.
- samatman 5y agoThis depends on whether they're wired in series or in parallel. Wired in series, mAh won't change, wired in parallel, it's additive.
- foobarian 5y agoMost commonly RC battery packs are referred to as "1S, 2S, 3S," etc. indicating how many single cells there are in the pack wired in series. Those are also individually rechargeable via a low-current charging cable.
- Ancapistani 5y agoYep. I'm very familiar with these from quadcopters. The charging cable is usually called a "balance plug", because it distributes power equally to all cells instead of shoving it all through all of them in series.
- atomwaffel 5y agoMy e-bike’s battery on the other hand is in Wh.
- skavi 5y agolaptops are always Wh in my experience.
- ksec 5y agoMobile Industry standardise on 3.8V, so you have two number to present to consumers, Wh or mah. Since Wh is a smaller number, marketing decided to use mah. Once that got traction, others that were previously using Wh had to follow. And now we end up having billions of consumers using mah as a unit and when they use it defaulting to 3.8V. It is all too late now. Sigh.
- bserge 5y agoYeah, it doesn't get worse than rock bottom. 5000mAh compact is around $20, 10,000mAh $40 for good devices.
- Kirby64 5y agoYou're not really comparing features to features if you're comparing to a boring 5000mAh brick with wired charging. Closest I can find is probably the Anker Qi magnetic brick: https://www.amazon.com/Anker-Magnetic-Wireless-Portable-PowerCore/dp/B08TW7BRTJ https://www.amazon.com/Anker-Magnetic-Wireless-Portable-Powe... 5000mAh, only 5W Qi charging, and $45. Again, not defending the Apple tax here, but it's not as far fetched as it sounds.
- bserge 5y agoOnly 5W? What makes Apple's 5W better (no, it's not 15W when portable)? But yeah, OK, you can attach it with magnets to the back, that's worth double the cost. Oh wait, make that triple, since you need the case. I better stop now, shitting on Apple was a favorite pasttime of mine. I mean, as someone looking to manufacture and sell a premium product, I'm pretty happy with it, people will pay anything for imaginary benefits.
- Kirby64 5y agoI missed that it doesn't support 15W charging when portable. That's erodes quite a bit of the benefits then. No reason you need the magsafe case, as far as I can tell though. Also, the Anker device does have magnets. Looks like they operate just like the magsafe.
- historyloop 5y ago> You're not really comparing features to features if you're comparing to a boring 5000mAh brick with wired charging. So wired charging is boring and magnetically attached is exciting? You know, this is not like AirPods, which are completely disconnected from the phone. It's a lump attached on your phone that you may also unintentionally disconnect and drop on the floor while taking videos of something. I'm way more "excited" by the cable, especially given the price (you can find pretty good 5000 mAh bricks for as little as $12).
