No. In general, a charger needs to be able to figure out when the battery has reached full charge, otherwise the charger can damage the battery by overcharging it. You need to use the specific charger required for the battery.
And, if you are trying to power a non-battery device that requires 1A from a 5V 100mA source, you will not be able to maintain 5V, so it will not work there either.

∙ 12y agoYes, a 1200 mA charger has a maximum output of 1200 mA. This is the design current that the manufacturer rated it for. One amp is the same as saying 1000 mA. The 1200 mA charger will have no trouble charging a device that is rated at 1000 mA.

Is it ok to use a 5v 1A AC adapter for a device when the original adapter is supposed to be 5V 500mA - will it damage the device?
Yes - what matters is the voltage - it has to be the same. The device will only draws 1A as needed - the adaptor with higher amp,i.e, 2A is fine. As long as the adaptor has amps equal to or greater than those of the device, it will be ok!
Can use 1A power pack for 500mA device?
Yes the power pack can supply up to 1 A, so 500 mA or 0.5 A is within that limit.
Can you use a 1A adapter instead of a 500mA adapter?
A one amp adapter is the same as a 1000 mA adapter. If your device requires 500 mA to operate then there is ample capacity in the adapter to operate a 500 mA device. Be sure to match the type of voltage AC or DC from the adapter to the driven device. Both have to be the same.
Can you use a 12v dc 1A powerpack on a device that required a 12 dc 700mA?
Yes, the device will only use whatever amps it needs.
Can you use a 9v 1500ma on 9v 500ma device?
Yes. (For any pairing of power supply and device, as long as the voltages are a match (in your case: 9v), and the output (in amps or milliamps (A or mA) of the power supply IS EQUAL TO OR GREATER THAN the current required by the device (in your case 1300mA or higher) then you will be fine. Yes it is suitable: The OUTPUT VOLTAGE (5v, 9v, 12v, etc) of a power supply MUST BE EQUIVALENT to the required voltage of the device to which it is to be connected, whereas the output CURRENT (500mA, 1A, 1500mA, 2A... etc) offered by the power supply MUST BE AT LEAST EQUAL TO OR GREATER THAN the current required by the device to which it is to be connected. (in your case, for example, as long as the power supply is rated at 9v, you could use one that has a rating of 1300mA, 1400mA, 1500mA, 1A...and so-on, without any damage to either device)
Can you replace a transformer with an input rating of 120VAC 60Hz 12W and output rating of 12vdc 500mA with one that has an input rating of 120vac 60hz 25w and an output rating of 12VDC 1A?
Yes, you can. Here's why. If a supply's output is rated at 12 volts DC (12 VDC) and 500 milliamperes (500mA), it can deliver a maximum of 500mA at the 12 volt rating. You want to use a 12VDC supply that is rated at 1A (1000mA). That means that the supply is capable of delivering up to 1A at 12VDC. Now the crux of the matter. Your device, that's the load on the supply, needs 12VDC to operate. Your replacement supply is rated at 12VDC. No problem. Your supply delivered a max of 500mA. That does NOT mean that your load, that thing you're powering up, actually uses all 500mA. Your load knows how much current it needs to draw. Your supply has to be rated for more than that. Your supply was rated at 500mA. It worked well. The supply you wish to use will deliver a max of 1A (1000mA). It will easily supply the current your load will use. Oh, and the polarity of the new supply must be the same as that of the old one. That's pretty obvious. Always be safe and consult an electronics specialist for electrical questions. There are a number of savvy folks working at consumer electrical outlets who can get you up to speed.
What fuse should you use for laptop charger UK?
A typical laptop charger draws less than 1A at 240V, so a 1A fuse should be fine. The power draw for a charger will be written on the charger itself, of course; you'll see something like "Input: 100 - 240 VAC, 1.2 - 0.6A". In this case, the two numbers at the right go together, so at 100V the charger uses 1.2A, at 240V it uses 0.6A.
Can a 12v dc 500mA adapter be substituted for a 12v dc 200mA ac adapter?
No.If it is AC output, it will blow out the power circuits of the DC device.If it is DC output, it doesn't have enough current capacity for the load of the DC device.If you want to power a DC device with a wall wart, make sure the wart is:DC outputCorrect polarity (some have reversible polarity)Exact same voltage as the deviceGreater than or equal to current rating of the device
Is 0.83A the same as 500mA?
No. 0.83 Amperes = 830 milliamperes. 1A = 1000mA, it's a base-ten system, just like meters or liters.
2 ports USB charger (1A). I was surprised at how much faster it recharged my phone than using my laptop port.?

Can you use a 12 VDC 2A adaptor on a 12 VDC 1A device?
Yes, there will be no problem with this adapter. The 1 amp device will only be drawing half of what the adapter can produce.
Can you use a 12v dc 1a power supply on device that requires 12v dc 3200ma?
No, 3200 ma = 3.2 amps
