| 1419850 | 2016-04-30 11:43:00 | We have two samsung phones in this home, came with a charger each, of course. Specs for the chargers: Output 5.0V 1.0A and the other: Output 5.0V 2.0A Can we use the higher output unit (2.0A) to charge both the two phones or we have to use the specific charger that came with the phone? |

| 1419851 | 2016-04-30 13:28:00 | Should be ok, won't necessarily charge any faster though. Depends how the charging circuit is designed. Phone chargers are really just power supplies, the circuitry that controls the charging is built into the phone and/or battery. | dugimodo (138) | ||
| 1419852 | 2016-04-30 21:09:00 | You can use the 2 Amp charger for both, each will only take what it needs. As dugimodo says, the phone may only draw 1 Amp and charge no faster, though. What I would not do however is use the 1 Amp charger on the phone that came with the 2 Amp charger. Depending on how its charge circuitry is designed, it is possible that the phone may try to draw 2 Amps from the 1 Amp supply and overload it, although I think that is rather unlikely. However, as a general rule, you should not use power supplies rated for less current than a device expects, due to the potential for overloading the power supply. |

| 1419853 | 2016-04-30 21:27:00 | Thanks guys for the inputs. Am I right to sum it up that it is safe to use the 2A charger for both the phones? Logically, (not technically, as I am not the expert in this area) the phone with the lower (1A) charger will not be damaged for using the 2A charger? |

| 1419855 | 2016-04-30 22:45:00 | Its not higher output. Its a maximum rating. The charger is just a power source who can not do much but pass on power and die of heart attack if the device it is charging tries to make it run faster than it can handle (overload). |

| 1419856 | 2016-04-30 23:19:00 | Exactly, the current rating of a power supply is only the maximum it can supply, you could connect your phone to a 5v supply capable of supplying 50 Amps, and the phone would still only draw 2 Amps if that's all it needed. The power supply would not try to force the full 50 Amps into the phone. | Agent_24 (57) | ||
| 1419857 | 2016-04-30 23:24:00 | Mind you, you would be better off with one of these..............www.harveynorman.co.nz I have a cheaper model |

| 1419858 | 2016-04-30 23:44:00 | I've got something similar to that pad, but for a Lumia phone. But it was a lot cheaper about $8 on Ebay. Instead of using power, I use a solar powerbank. Which supplies 1/2A Does a pretty good job. |
