Power Supply – Power Bank : Raspberry Pi

by **tml3nr** » 09 Apr 2016, 06:14

When playing music from wireless NAS, my Pi 3 use 0.3A. When i shutdown by Rune, it's about 0.1A. Two leds on.

With Asus ZenPower 9600 power bank, when shutdown by Rune, all about off. Maybe it (power bank) off when below a certain threshold power consumption?

As @tml3nr shared, I used 2 power-bank batteries: 1 is Asus 9600mAh and 1 is ZTT 10000mAh. The Pi2 red led is off for the case of Asus after Pi2 shutting down but it is still on in the case of ZTT. That may be the battery it has the threshold board inside to control the supply.

I agreed with PeteB's concern: the issue is how to turn the Pi on. If it's consumption is not much I prefer to maintain it on or a standby rather switching it off. In any case, use RuneUI to turn it on/off for both cases should be useful. Hope it can be done in next release.

Hi @PeteB: The battery banks they have a button so we can turn the Pi on by pressing it simply. So you go with it?

I'm waiting for my 160000 power bank.
I will test it and after it I will leave my feedback.

I have just build a linear power supply with a LT3083, to feed my rpi3 with hifiberry digi+. The power is connected directly to the hifiberry and that also feeds the rpi. The sound is improved a lot, surprisingly :-)
