Hi guys,
I have a 26 Amp/Hour power supply, 3.8 Amp.
My question is, Due to my knowledge in the Electrical Equipment, that the Amp/Hour is for the batteries only which is mean how long battery lasts.
But the power supply generate a Continuous Voltage forever So, why my power supply is 26 Amp/Hour ?

Thanks.
 
the Amp/Hour is for the batteries only which is mean how long battery lasts.
Correct.

why my power supply is 26 Amp/Hour ?
I don't know.
Stupidity/confusion/ignorance on the part of the manufacturer/supplier?

Do you have a picture or some information that you can show us about the power supply?

hi,
The specification you posted says: Power supply/Charger.
Does the unit have an inbuilt battery, I have seen similar units for camping/caravanning that have an internal battery.

The 26 Ah refers to the maximum size battery it is designed to charge:

EDIT:
It is apparently designed to charge at C/20. That is, a battery capacity of 26 Ah/20 = 1.3 A, which is maximum rated continuous current it can supply.

This is not a power supply as would normally be understood in the context of a discussion about electronics.

It is a power supply which works in conjunction with a built in, or, external battery pack.

In which case, what I said earlier:
Stupidity/confusion/ignorance on the part of the manufacturer/supplier?
was unfair on the supplier/manufacturer.

With this new information supplied by the OP, manufacturer/suppliers description seems to be quite correct.
