Power bank which charges automatically

aaz01

I need a USB power bank which charges a mobile phone automatically when the phone is connected to it.

All of the ones I can find need you to press a button after connecting the phone.

It's for an in-car build I'm doing and I won't be able to press the button.

Anyone know of one?

How strange.


Conversely to you , I have never seen one where you have to press a button to initiate charge !!
Nor can i find one by googling about

I've got some from Tesco with no buttons but unfortunately they don't sell them anymore. One of the ones I got from LIDL automatically powered too, but they don't sell their anymore either. Models change very quickly

Also, as its for a car build, can you not tap into the 12v supplied to the "ciggy lighter" and use an adapter hidden away under a panel, with just a charging lead protruding from a hole somewhere ?

Why are you using a powerbank in a car when there is a massive 12v powersource?

I have powerbanks with and without a power button. Lots available with and without. If you cannot find one i presume you have never been on ebay.

Poundland ones don't need turning on, but they're pretty low capacity.

Better banks often do need turning on they have displays or negotiate cheering at higher voltages.

I have an "Anker Astro2 8400mAh" which needs a button pressing.
Will be out of date now I bought it 5 years ago.
