Power Bank Recommendations.

[Wendelspanswick]

In a previous post someone recommended a Tecknet Bluetek power bank quick charger so I bought one (about £16) and it's brilliant. It will fast charge my Samsung phone while slow charging itself from the 12v supply in the van.
The problem is that they are no longer available and we want to buy 10 similar power banks to use as back up power supplies for Raspberry Pi's.
They need to have at least a 2.4 amps output and needs to charge itself while charging the device connected to the output (lots don't).
8000-10000 mAh would be fine.
Any recommendations?

Not really what you are looking for although the specs are close..

Rechargeable led floodlights with usb power output sockets.

They do send power out at the same time as charging themselves up.
Plus they are a light which may or may not be handy for 'backup' ?

Nice thought but they need to be velcroed to the back of a wall mounted TV.

The three brands I stick to are Anker, Ravpower and Xiaomi. I know they all use quality cells or at least they did when they were 18650 powered, now they have all gone to lipo packs, I’m even more cautious of these so quality brands matter.

I’m not sure if they charge and supply output at the same time.

I’ve been using Anker p/banks for the last 3/4yrs. Good gear
