currently, i own 2 android phone, samsung G5 and ideos X5, both comes with their own micro usb charger.
samsung travel adapter - output : 5.0V == 0.7A
huawei power adapter - output : 5.0V == 1.0A

anyone know whether i can just use either one of this charger to charge both of my phone? will it cause any problem like inadequate power charge/etc?
thanks.

not advisable to share charger... will damage the battery life i guess...

buy multicharger

what do u mean by multicharger?

both the charger that I hv is the same microusb type, having same voltage output but the only different is the Amp output..
thts why i wanna know whether it's possible just to use one instead of both to charger each of the phone.

no worry. batt IC will know when to show you full charge.

that means it's ok to use huawei power adapter - output : 5.0V == 1.0A to charge on the samsung phone?

which the charger can let u charge all type battery ~

do u hv 1? can I know whats the output in term of volt n amp?

Amperage is no issue especially when they are this near. Just use, no problem.

oic.. me nt very good in term of electrical stuff, better be safe then sorry...

IMO, if the voltage is the same, it should be fine i guess.

Indeed. Sometimes, it only take one flip of switch to damage your electrical item if they are not compatible.

In your case, i think it is ok to proceed as the voltage is the same. I can charge a few Nokia phones with a few different Nokia chargers with different output "A".

thanks for everyone for the comment.. found this which is quite informative for me.

i also saw some article mention that higher amp charger will charge the phone faster but would degrade the battery sooner..
is this true?

Both charger are okay to use as long as the Output Voltage are the same. Not much ampere difference so it won't dmg ur phone.

It's ok. If output lower will cause problem then what about charging when you plug into computer USB port which is significantly lower than wall output.

i not EE, but some phone itself do have built-in Amp regulator. using 2A should not be issue.

if u worried it damage, the pick the lowest Amp as universal charger. but u will notice device take longer to charge full.

wont damage your phone. no worry.

I think that is true for me. However, I think the main cause for the battery degradation caused by user is that they tend to use the phone to play game or chit-chatting when charging them. duh....

Thats because PC USB Voltage output is also 5V. Anything lower than that, your phone is in trouble

Lower is ok. It won't charge. If higher, user might be able to smell the hangus smell...

lower amp is fine unless your handphone able to adopt different of load and adjust the charging speed without burden the USB charger...

if the handphone are hunger for power and must use certain amp to operate the charging functionality... if may overload the USB charger, overheat and burnt... worst come to worst, the insufficient load may damage the handphone, but for current technology the handphone should able to adopt at least computer's USB port's power load...

example: i used a power adapter with 1amp only for a equipment, end up the power adapter overheat and burnt after 15 minutes usage... as i checked with adjustable PSU with same voltage, the equipment required 3-4amp at least... means the equipment sucking more power from power adapter and more burden...

what if.. i use the huawei power adapter with higher amp (1.0A) on my galaxy 5..
I know that my x5 need more charging power compare to my G5 based on the screen size, cpu, etc..

will it cause any harm?
or there is way to check on this? maybe some indicator on the battery or somethin like that?

huawei power adapter - output : 5.0V == 1.0A

Added on June 15, 2011, 9:15 amoh.. doesn't they hv some internal breaker or somethin like that?
once it detected the voltage too high, it will auto cut of the power..

Higher amperage is okay if the voltage is regulated. 5A also no problem. Take current as the adaptor's capability. Voltage is the force.

I think it’s not compatible to share with two kinds of phone

Hmm, last time when i tried to charge a N97 mini through my emergency charger with a very low output amperage and it did not charge. Also, if the equipment is switch off during charging, the risk you mentioned still exist?


Most branded smartphones have it, but not 100% of the phone have it.

5A also no problem? I really hope to see there are emergency chargers with that kind of output seriously. Most of the emergency charger takes too long to charge the phone battery during outing......

example:
our house TNB power source is 230V @ 13amp... but u used 230V @ 1amp++ equipment without any issues...

but if u using the equipment required at least 15amp, definitely will overload the wiring and ELCB may trip...

FYI, our common USB port just deliver 0.5amp to USB devices, believe most of smart phone users used the USB port to charge their smart phone (if forced to do so)... due to this issues, most of motherboard manufacturer offered the USB port with higher amp 0.9-1.8amp if detected smart phone for charging purpose... it can be fasten the charging speed and reduce the USB port's burden...

but still still recommended to use the stock charger, believe that they have the reasons to design the power adapter based on their hp's requirements, maybe some hp cant suit with different power adapter... otherwise maybe the cost concerned to manufacture power adapter that higher amp = better component = higher cost...

anyway, i have a adjustable PSU which can support up to 30V @ 18amp, but i plug the power source on customer's equipment for check up purpose which required 12V @ 2amp (of course i have to adjust to 12V as ouput butamp load no adjustable)... no problem so far...


it can be the safety features of the handphone to prevent overload ur power adapter and ur handphone forced to suck more juice from it...

in the market have 5amp power adapter, as what i said cost concerned and lead higher price which doesnt bring much beneficial to hand phone users and manufacturer as hp just required around 1amp...

but... i still will stick with my stock charger to prevent unnecessary hassle in the future...
