The one amp on the mod spec is pretty much just telling you it is rated for one amp for charging the battery. it shouldn't be a problem plugging in a 2 amp plug into it. It should definitely be fine with 1 amp, but any higher, it will regulate it down to 1 amp. This is probably because the internal battery isn't rated for a charge rate very high.

There are a lot of charging circuits on chipsets that regulate what they need and others that do not. Best advice most of use give is do not use a wall outlet converter (adapter) that outputs higher than what the mod uses or the charger accepts. If it says 1amp input, max wall outlet output 1amp, though a 0.5amp would take twice as long, a trickle charge like that is gentler on the batteries and make them last longer in the long run. If the wall outlet outputs 2.1amps (Apple iPad wall wart as example) I would not suggest using on a mod with a charge circuit that accepts max of 1amp.

If that is all you have, I'd suggest investing in a simple Android charger, $10USD wall adapter is far cheaper than replacing a whole $60USD mod.

Thanks for the reply! So I have a Samsung outlet for my old Note 2, should this suffice? My mod has these protections built in, not sure of these are at all relevant to my question, but here they are.

  • Low voltage protection
  • Short circuit protection
  • Over-current protection
  • Over-voltage protection

most generic "chargers" actually put out more than whats on the label... volt wise and current wise. The specs on the unit are usually the rating under load and will increase a tad as the load requirement decreases... e.g. as the battery becomes charged, the voltage and current continue to climb to the no load voltage and current capacity of the charger.... which in most cases is 5.5ish VDC.... ( for a 5V unit) Ive seen 12VDC wall warts output 15VDC.... :shock:

Damn, I didn't know that! What would be the best thing to use to charge my mod in this case? Can never be too safe with these things. I'm also thinking this mod has LiPo batteries in it, need to be more safe lol so yea, what would be the best thing to use? This mod did not come with a charger or USB cable of any sort, it's just sold without one.

Hey guys! This is a complete noob question, so I figured it belongs here. So I have a Tesla Two Sub Mod, and it says on the charger port is charges at 1amp. My question here, is if I use a phone outlet that is a bit over 1 amp, is this dangerous? Or does the mod itself know to charge at the correct pace?

No.

If you use a 0.5 amp outlet, it just means your mod battery will take long to charge.
If you use a 2 amp outlet, the mod will only draw 1 amp max anyway.

The charger is in the mod and it controls how many amps it gives the battery. The USB port, be it in a computer, a wall wart, or something else is simply a power supply that outputs a voltage close to 5V and is rated for a maximum amperage draw. Your charger in the mod will not take more amps from the USB port than it wants to no matter how many amps the USB port is rated at.

I have a mod with a built in battery and a built in quick charger that connects via USB cable. It draws a bit over 2A in its first charging stage. The first time I charged it I used a 1A wall wart (I was impatient and didn't want to wait until my higher amp rated wall wart got to me) and the wall wart heated up to a point I was uncomfortable with after about 20 minutes. I stopped the charge until it cooled down and reconnected it. I did that twice to get it charged and never used a 1A wall wart with it again.

I got one of these 2 port USB adapters rated for 2.4A per port and heat generated became acceptable to me ... just slightly warm during the high amp initial charge stage.

I also bought one of these USB voltage/current testers to let me see what amps and voltage the USB port was actually putting out. Neat gadget for $10 :). Here's a review of it on lygte-info.de. It also tells you how many total mAh were put in the battery which is also useful.

I don't charge many things with a USB power supply, but since I got the Ravpower it's become my go-to wall wart for all of them. Chargers that only draw 0.5A charge just fine at 0.5A and I'm not stressing this 2.4A beast in the least.
