AC to USB Charger Question

[nismo95tt]

Hi All,

I have a question about charging 3 separate devices with an AC to USB charger. I've been searching high and low to try and find the answer for- but so far, no luck.

I was hoping since this is somewhat phone related, that the knowledgeable members of PPCGeeks could finally shed some light on this one for me, with a definitive answer:

Here's the situation:

I've got 3 devices that I carry with me at all times:

Sprint HTC Touch Pro
iPhone 1g (for use as an ipod touch for music, apps, and games)
Jawbone2

I've got 3 separate AC to USB chargers that came with each product. Here are their specs:

Sprint HTC Touch Pro:

INPUT: 100-240V - 0.2A 50-60 Hz
OUTPUT: 5V - 1A


Sprint HTC Evo 4G

INPUT: 100-240V - 0.2A 50-60 Hz
OUTPUT: 5V - 1A


Palm Pre/Pixi:

INPUT: 100-240V - 0.2A 50-60 Hz
OUTPUT: 5V - 1A


iPhone 1g:

INPUT: 100-240V - 0.15A 50-60 Hz
OUTPUT: 5V - 1A


Jawbone2:

INPUT: 100-240V - 0.1A 50-60 Hz
OUTPUT: 5V - 550mA


I'd like to ONLY carry one of these AC to USB chargers with me, to charge all 3 devices (one-at-a-time, obviously).

I'd prefer to use the iPhone AC/USB charger since it is physically the smallest.

Will it be safe (in terms of battery/device health, fire hazard) to use any of these single AC to USB adapters with each of the 3 different devices?

Thanks in advance for any help that anyone can provide.
