I have a rechargeable vacuum that I’ve lost the AC adapter for, and it has this sticker on it:
My question is, if I buy the adjustable AC adapter linked to below this sentence, can I use that AC adapter to safely and efficiently charge up the aforementioned device?
I know virtually nothing about this type of thing, but one of my concerns is that the appliance label alludes to ‘500mA’, but the AC adapter details state that it can be adjusted to any of the following, none of which are as low as 500mA:
‘Input: AC100-240V 50/60Hz
Output: can be adjustable for choose:
DC 3-12V 5A
DC 3-24V 2A
DC 9-24V 3A
DC 3-24V 3A
DC 1-24V 2A
DC 9-24V 1A
DC 3-12V 3A
DC 3-12V 2A’
The pic of the AC adapter in the ad clearly indicates that it is ‘REGULATED’. A friendly guy at Jaycar reckoned that meant that it would not supply more charge to a device than that device was supposed to handle … but some reading I have done on the net suggests to me that that is not the case.
Can a learned sparky out there set me straight on this please?
If I bought this AC adapter and set it to ‘DC 24V 1A’, could I expect it to charge the device, without frying it? I’m pretty confident that the 24V would be sufficient, but I am worried that the AC adapter would in fact deliver a full 1 amp (despite being ‘regulated’), and fry the unit.
