Can I Use A Charger With Higher Amperage


I want to power cpe modem of 12 v 2A with a closed lead acid battery of 6v! So I made a mad dash to Radio Shack to replace it. If it doesn't match then the fix is simple, just cut the jack off and swap the wires around. It turns out there’s a method to all this madness — but first we have to explain how USB power actually works. weblink

Anonymous OK, thanks for the clarification :) thomas kim This is a bit misguiding, read the first reply first up above. Though i can charge other devices with that charger. THAT's intelligent innovation. the original adapter says 4.85v 800mA.

Can I Use A Charger With Higher Amperage

Current too high – If the adapter has the correct voltage, but the current is greater than what the device input requires, then you shouldn’t see any problems. migrated from serverfault.com Aug 5 '10 at 6:18 This question came from our site for system and network administrators. Or, the device may power on, but the adapter may not be able to keep up, causing the voltage to drop (see voltage too low above).

I am currently risking using an IBM Thinkpad adaptor (my old laptop) after checking the specification. Your computer will "pull" more amps when it's working hard than when it's not. The key is to match the DC output of the adapter to the DC input of your device. Can I Use 19v Charger For 19.5v Laptop Therefore I was hoping I would just plug that into my iPad charger and charge it without blowing it up.

Buy now! Laptop Charger Different Voltage If an OEM wanted to, it could program the USB controller on the device to only talk to an "authenticated" USB host/charger. The current rating of a supply is what it can deliver, not what it will always force thru the load somehow. https://askleo.com/can_i_use_a_charger_that_provides_the_same_voltage_but_a_different_amperage/ Wireless charging is also branching out from its roots to become even more useful to consumers.

A Vita and Nook Color can use each other's chargers, since they're both looking for that data short, but not most other non-computer chargers. Can I Use A 12v Adapter For 6v Device: 6V 1A Adapter1: Output: 12VDC 500mA Adapter2: 15V 1.5A Adapter3: Output 7.5VAC 350ma :S any advice would be great thanks. How was I able to just plug in my headphones and listen to ATC and pilot chatter? The device could power on, and just draw more current from the adapter than it’s designed for.

Laptop Charger Different Voltage

The charging downstream and dedicated charging ports provide up to 1,500mA (1.5A). USB 3.1 bumps throughput to 10Gbps in what's called SuperSpeed+ mode, bringing it roughly equivalent with first-generation Thunderbolt. http://lifehacker.com/does-it-matter-which-charger-i-use-922783980 Don't Miss a Single Tip! Can I Use A Charger With Higher Amperage Using try/catch for preventing app from crashes Do men and women have the same number of genes? Can I Use A Charger That Provides The Same Voltage But A Different Amperage Unfortunately the comparatively high set-up cost and lack of consumer device support is really slowing adoption.

God bless Reply MikeM December 29, 2015 at 2:46 pm # If I am following this thread correctly… my "old" AC Adapter specs: -AC Input: 100 ~ 240V 50 ~ 60Hz The charging procedure is performed at constant voltage with current-limiting circuitry (i.e., charging with constant current until a voltage of 4.2 V is reached in the cell and continuing with a Iphone and Android devices use DIFFERENT charging methods. Polarity This one catches many people by surprise, especially when replacing simple or small power supplies with generic replacements. Lower Amperage Laptop Charger

You could buy the 65 watt adapter and *probably* be fine - it produces nearly as much power as the original, and your device probably doesn't draw its maximum current most But when I am using a 5V 1A charger, the charger heats up fast. (And smells foul when I am very near it) When I tried using a 0.7 A charger, What is the reason to use the Heal skill assuming that other means of healing are not prohibited? I’m willing to bet that any given household has a dozen or more of different types of cell phone chargers, AC/DC adapters, power bricks, power cables, and charger plugs.

Check your power supplies before you travel, of course, but it's very, very convenient.

It has helped. And, some SMPS can have minimum load currents. –Thomas O Jun 29 '12 at 7:58 5 @clabacchio and others: Yes, there is a lot more that can be said about The result or potential resultdepends on the device it is used with. Power Supply Amperage Too Low The phone battery was hot and the phone was inoperable.

Jocy John February 17, 2015 at 8:07 am read all the article , one doubt. You can choose which port did you want to connect the Samsung Galaxy Note 3 to the powerbank. Name: Subject: Message: Wireless charging technology: what you need to know Featuresby Robert TriggsJanuary 11, 2017 33 10 Wireless Charging has had a hit a miss relationship with the mobile industry, I'm sure other companies can use it too, but they're too stupid or cheap to do that.

What these outlooks don’t take into account is the various protections and versatility of adapters and devices. A 9 volt 5 amp supply is a superset of a 9 volt 2 amp supply, for example. The device may work with voltages that are close, but often at the cost of shortening the lifespan of the batteries being recharged. Additionally, the OUTPUT values as printed on the bottom of the induction charger are 12V and 500mA.

When the device sees shorted data lines, it knows that it can draw up to 1.5A -- that's what the Battery Charging Spec dictates. Not the answer you're looking for? As mentioned earlier "Amperage is taken by (or pulled) by the device being powered" lot of cases we experience when the ampere in the power supply is more the device regulator Hard to read black sharpe on black adapters… 😉 Reply Barbara June 30, 2013 at 9:10 am # I put nail polish dots on my cables AND the devise.

that is a wise choice. Forum Rules | Contact Forum Editor | Report a Post Mobile charger with slightly higher output than required-how safe? OriGuy I think this is WebOS doing this, not the Touchpad hardware. As far as current goes, the device calls the shots, and the adapter will have to do less work.
