Re: Battery bank - charge and serve at a time

Dragging this up again!

I have actually ordered one of the Tecknet Power Banks.

I can confirm that it will allow powering and charging at the same time, which is great. However it doesn't seem to power the Pi Zero for much longer than 30 seconds if not connected to the mains as well.

I'm not sure if this is down to the fact the Pi Zero only draws minimal power or something else.

Anyone else come across this?

According to Amazon questions and reviews, there is a brief power interruption when it switches from AC to internal battery.
There is however this product: http://a.co/9xRU1ee which is exactly a USB micro UPS. I use it on my raspberry pi for this purpose. Works great.

Any updates to this whole idea of using a battery pack?
It's tricky - and the short answer is "There's no canonical answer."

I've tested several battery packs to try to get one that works (where by "works", I mean that you can both charge and run it at the same time, while the Pi is running - and, most importantly, that when power is removed from the charging side, the Pi does not crash.)

Almost by accident, I found one (one of all those I tested) that works (but see below). The on that works is called a "3G Wi-Fi Router" and cost about $15 on Amazon. Yes, it is billed as a 3G router, but a) I was never able to get it working as a router and b) it also serves as a battery backup unit.

However, the glitch is that it worked - for about 6 months (of 24x7 use). Then it stopped working (and could not be revived). It basically "wore out" - which is something that electronics are not supposed to do, but it did.

I never had any urge to replace it.

I am currently using a Kolumb 5000 mAh (kolumb Ultra Portable Pocket Charger: One All USB Electronics Design, External Mini Backup Battery Pack, Basic Power Bank Cell Phone iPhone Android HTC (5000mAh, White Adapter iPhones) from amazon, around $16. I can plug it in to my RPi 3B and to 5v 2.4 amp Pi supply at the same time. I can leave my pi on for days. However if there is any disturbance of the plug into 110 v supply or of the 5 v between the 110v brick and the battery, the power to Pi is turned off and on very fast, but the Pi reboots. So I like you am looking for the in between battery that will keep supplying power to the Pi without the reboot. This is light weight and cheap but doesn't bridge 110v disturbances. That said I do have one that does, albeit heavier
The "XTPOWER 10000 mAh /37w Mobil Power battery Li-polymer does not shut off when 110v ac is disturbed, you can plug it in, unplug it and my Pi just keeps on green light going. It has several outputs and has 4 big leds on the front showing charging or level of charge Amazon (XTPower MP-10000 External Battery Pack with 10000mAh - dual USB 5V + DC 9V / 12V 2A for Tablets, Digital Cameras, PSP, NDS, ) about $60.00 it comes with a variety of output voltages and plug adapters, I bought to charge my cameras and phone. It comes with a car adapter for input power so camping with your Pi is ok.
I use my Pi to display 2 pages of music full size on a 24" monitor when I'm on the road.
