This is a merged topic combining a number of threads about the V’s compatibility with portable battery banks.
The answer to this popular question is: Any charger or battery bank following the USB-PD standard should work, but only use of the supplied Eve power adapter is officially supported and covered under warranty.
As good as the V’s battery will be, it may still need a boost during a long day of being out and about. I’ll be busking with it all over NYC (heavy CPU usage; sampled pianos and Abelton loops of lots of drums and percussion, bass, and other instruments), and will use it at Jazz clubs afterward for a quick look at any tunes that I might not know as well as I should. So I’m looking into a charger, with weight and size being prime considerations, as well as not having to bring the V’s wall wart & cord.
On the Acer community for their Alpha Switch 12 (a V and Surface Pro 4 competitor), a poster stated that THIS:
charger worked, via USB-C, due to the variable voltage (30 volts, in this case).
OOTH, THIS ONE has 65 watts of output, but not via USB-C; it’s via an ac plug, which means bring the wall wart:
I already had this concern, so I participated in the IGG campaign and received a Pro model unit earlier this year. It has a cable option for USB-C. I am very pleased as my unit that has output 120v of 100W and a battery of 20400 mAh.
I have a CLEVO P650SE laptop and can be charged directly with a cable that comes along with the Omnicharge or the AC port.
I’m sure it will give me much more hours of use not V out of the outlet.
More information can be found Omnicharge IGG.
Is your tablet also called Eve V?
It was strictly said that with Eve V, you can’t use Qualcomm chargers. And it voids the warranty.
I won’t get into the details of how it works because I don’t know it well enough, but from what Peter said, I understood that Qualcomm uses a different communication protocol for setting the voltage, so it might sometimes start sending, for example, 12V while the tablet was only expecting 5V. Basically, Eve V doesn’t speak Qualcomm language and Qualcomm language doesn’t speak USB-PD language.
If you use a 220V socket (although I didn’t see one when I looked at the battery linked above), there will be no problems. But it’s horribly inefficient as the energy needs to be converted from DC to AC and then back to DC, in addition to changing the voltage from 3.7V up to 220V and back to 5-12V. So it can be used, but a significant part of the battery capacity will be “lost” in the conversion.
The chargers are using Qualcomm technology. Go ahead and use them, I’m not stopping you. But I did warn you that it WILL void your warranty.[quote=“Jeffrey_Newton, post:14, topic:5541”]
Isn’t’ there a brand of cell phone called "Qualcomm?
No, Qualcomm makes mobile chipsets (processor + radio modules, charging circuits, basically all in one chip).
If you see “Quick charge” mentioned somewhere, that means it’s Qualcomm because it’s their trademark.
