“Pri” as in Primary winding/Input. Its the Mains voltage of your home and then converts it to 9 volts which is the voltage your machine uses. You didn’t specify the type of voltage for the 9V…does it have a “~” symbol? or a line with dots under it.
There are 9v power banks out there but Anker doesn’t manufacture them. There are also USB step up converters that output to a coaxial power connector. But without much information of the exact model of your device I wouldn’t know which type of connector you need (most likely coaxial type…then there’s the issue of what size, since they vary)
Well can’t be true. Something you told us is not valid.
USB is 5V and yet your round end is 9V. Hence there would have to be a buck-boost inside which is physically bigger than just a voltage drop. Hence either it is more than just a simple cable, or there’s more information on a label somewhere.
Anyhow, what I can infer is the Wattage is very low but not so low it intersects all Anker products, so I can eliminate some less likely to be a good match. 9V-800ma is 7.2W so assuming 5W and say 20% power loss = 1.8A
Hence any of these will power you USB “simple adapter” to the round pin.
Powercore Slim 5000
Powercore 10000 as these are all at least 2A output
and then everything else higher in cost.
Less likely to be a good fit would be:
Powercore+ Mini as these are 1A output.
We must then to narrow the recommendation must work out how big an Anker powerbank you need. To do that can you let us know
is there any more you can tell us like mah, Wh?
how long does it take to recharge your device?
how warm does it get when recharging?
how long does your device last on a charge?
how long would you like it to last?
From this I can guess within an accuracy of factor of 2.
Also, if you know make/model GIYF (we can search for information).
The only possible solution to the way you want to do it, is by obtaining a “step up voltage converter”…making sure it’s rated for at least 2A. Qualcomm Quick Charge technically can operate at 9v ~1.6A but I don’t know how you can make it specifically output that voltage. So your best bet is on a step up converter… which you can get and use at your own risk. Just making sure that the size of the coax end is the same as for your device.
I plugged into the 2A USB socket in the Anker 15000mah and pressed the power button, it came on briefly then went off.
The second SL40 is the one I have.
In view of the ‘Charging notes’ I think I should email Toby Churchill technical and ask for more advice. I had been told by one of there Agents that I could use an external power source
I’d say given your USB cable is just a cable, and given the 9V input, I think it is not actually following USB, it just a USB shaped plug. That is consistent with your existing Anker 15000 not working.
Yes, contacting the manufacturer will help. A USB 5V to 9V converter may help, then you can use almost any Anker USB portable power. There are also non-Anker portable power products which output 9V, but at significantly more expense.
Hi, You asked earlier about how long the battery lasted, over Easter was a lot of chatting and within 4 hours the warning light was on, so I thought the backup power source would need to be either the Anker Power Core+ 26800 or the Anker E7 26800.
What do you think?
