I love it, except for the fact they explicitely state it's not waterproof. Given the backpacking and otherwise emergancy nature of one of the major selling points of meshtastic? that's a key feature that needs to be implimented.

Given the connector it's got, I suspect it might be splashproof or intended to be/become water resistant in a future iteration.
That's what I'm thinking too. Why have a PoGo port if you don't plan on waterproofing. I already have silicone plugs for USB-C ports.
Lol what the hell is that marketing video?
You're....walking in the woods....And then suddenly you're....uh....flashbanged? And then you're in the back of your kidnapper's car with a convenient Heltec device to communicate with?
I honestly have no idea what the actual fuck happened in that marketing video.
Thanks for sharing, bought one to experiment with Meshtastic :D
For your second node, since you're gonna get a second node, get something with replaceable antenna. There's a huge difference in signal between the small stock antennae and something like this.
Has anyone got their yet and want to share some insights about it?
I ordered one but it hasn't shipped yet. I'll post once I get it.
I ordered a 5,000 mAh to try out. It saves me from building something similar myself. Prototyping wireless charging is hard enough as it is without taking radio interference into account.
Did you find out how thick it is?
Only based on what the listed specs are (11-12 mm). They don't ship until April 25th.
By chance, do the numbers seem a bit off to anybody else? From what I understand, the battery capacity is 5,000 or 10,000 mAh, but yet it's only being rated for 3,500 and 6,500 mAh. I heard the bottom 5% is being reserved for the mesh node itself, but that should mean the rating should be for 4,750 and 9,500 mAh.
It seems those ratings are the internal battery size at 3.7v, and then the 6,500mAh is the actual capacity at 5V.
Well, your phone needs at least 5 volts. So it sounds to me as though if you're using the node, then it can take advantage of the entire battery. But if you're using it to charge your phone, you can only take advantage of like 70% of the battery.
I don't know, I personally saw it as dodgy marketing honestly.
That's the standard - listing the raw cell Ah - and it always has been dodgy. I guess in this context ironically it seems more dodgy because they also list the effective capacity. :D
Yeah, that's kind of what it seems like to me as well.
I think their marketing just screwed up, they're supposed to rate output in Wh, not Ah.
I think they just messed up the units, 6.5Ah * 5V = 32.5Wh which seems reasonable from the 38.7Wh battery, as that's a total of 84% efficiency which is pretty typical for a power bank.
So it should say rated capacity = 32.5Wh.
Most battery banks advertise their raw cell Ah/mAh ratings, which of course isn't the effective Ah at 5V. It seems like Heltec tried listing both ratings here.
Yeah it seems like it. Cell capacity is fine in mAh but output energy should always be Wh
The magnetic wireless charging part seems a bit useless, but the idea to combine a usb powerbank with a LoRa meshtastic device is pretty awesome.
Right. Another really interesting idea in my opinion would be to integrate an SX1262 into laptops. That way, if you're ever off network, you can at least have a low bandwidth communication method.
I don't plan on using it for wireless charging (although I could) but it makes it easy to carry alongside my phone using the Qi2 magnet pattern.
I would think it would weigh too much to actually stick it to a phone with a magnetic back. I think it's more for just setting the phone down on top of it and getting a charge from it.
Edit: Eh, 140g. That may be possible. Though having it stuck to your phone would end up making your phone over 300 grams and possibly over 400.
