    Recently purchased the OEM Galaxy S5 spare battery kit from Samsung's official site. I noticed that the included wall charger is rated at 0.7 amps/5V (USB 2.0). The stock charger that shipped with my Verizon S5 is 2.1 amp/5.3V (USB 3.0).

    Any harm in using my phone charger and cable for the battery kit? It can accommodate USB 3.0. There's quite a difference in power and I'm wondering if there's a battery longevity issue with using the higher amp charger. Thank you!

    The Charger should only use the Amperage it needs . They ship it with a lower rated one as that's all that is needed to charge the battery, the Phone one is higher as they know you might be using other functions on the Phone while charging the battery as well. But the standalone will still only pull the .7 it needs off the higher charger .

    It's like putting a new LEd bulb in a light fixture the old ones need that 60watts but the LEd only needs 20 or so and will only draw that.
    If that was an issue of over draw it would blow the LEDs every time.
