External Battery Pack for H100 Series

[DeadMan]

I am still waiting for an answer from iRiver. 3 emails sent now in the last 2 weeks and no reply.

[DeadMan]

It's like "We do not have a form reply to his query. Oh lets just send it to junk and ignore it" :P

Hence the well known equation:

W=VA

I have a practical question regarding the H120 and watts, volts, mAh etc. The cost of electricity is my area is 6 cents per kwh. How much would it cost to charge up my iRiver if charging time is 3 hours ? The specs says the external adapter is 5.0 V, 2A. According to your formula W=VA, is it just a matter of multiplying 5.0*2 to get 10 watts. So is the cost .01 kw *3 hrs * 6 cents = 1.8 cents ? (which seems a bit low ??)

[Mr Whippy]

'bout right. Cost is in pennies. Not like using a three bar electric heater all night

Nokia chargers have the same polarity as the iriver, but only need 3.7v
Try it, it wont hurt the iriver, worst that will happen is that the charger wont work & it wont charge with only 3 batteries.

ive never tried 6v so not sure if its ok. Has anyone??

Zeez!

Well, I made a big mistake. turns out the nokia charger I found can hold 3 AAA's. not AAs.

I also tried to plug the charger into my 120, (without batts of course) but the center hole of the plug is too small for the pin inside the 120.

[zezayer]

Oh well, we all now know not 2 use the nokia chargers for the iriver.

A i was saying before, easy enough to make your own, only involves connecting 2 wires, or no effort if u buy the battery pack from maplins.

Nice try tho, wouldve been good if it had worked.

[NPswimdude500]

target (and other stores, i presume) now have chargers than are disposeable for nokias. there was one with the correct size pin hole, but i'm not all that sure about whether they can be used or not....plus, they're $10

[DeadMan]

iRiver replied. They basically said they don't support it therefore won't give a definitive answer. :P

D'you think 3 AAAs would be enough to charge the ihp-120? I can always change the plug of the charger I found.

I've just recieved a set of Travelsound 200's for my christmas and was wondering if I can use the iRiver H3** charger to run the speakers? The H3** charger is 5V-2A and the travelsounds require 5V-1.2A. Can someone please tell me if the ammps will have a negative effect on my speakers, ie. will they blow them up or something?

Thanks

I'm fairly sure that the current rating on the charger is the maximum current that it can supply to a device, so if the speakers will only draw 1.2A even though the charger can supply up to 2A. So i think you should be fine.

I've used my H1xx PSU on my Travelsound speakers and my Travelsound PSU on my H140, zero problems, in fact I've taken to using the Travelsound PSU all the time for charging my H140 because the plug is longer and holds in better than the original PSU as the player has an iSkin on.

edit: if you're wondering about using more amps on the speakers than the Travelsound PSU supplies, don't worry the speakers will be fine as they'll only take as much amps as they need

[damagician]

That's great. I don't know very much about electricity and wouldn't want to blow my brand new speakers. Thanks for helping me out yet again Mistic River ;o)

Hello i have a question for "technicaly challenged guys",

Okay i must admit i've not made my "battery pack" by myself... Indeed i bought recently the Boxwave minisync (with charging plug) and also the battery pack that plugs into the minisync to recharge the iHP with 4 AA batteries...

The issue is that if i use AA not-rechargeable cells (aka LR6) i'll get:
4x1.5V=6V this is more than the required 5V I imagine it will fry my iHP...

So the other solution is to use 4 NiMh rechargeable AA cell that are 1.2V (each one). The i'll get:
4*1.2V=4.8V ok then it isn't to much but it isn't really enough since 4.8V<5V... :/
Will it be an issue?

Another question is that: the Boxwave battery pack is made to fit into the minisync which will be pluged into the iHP...
So is there any "resistor" that adapt the 6V entry to 5V output (according to the USB specification)?
I'll ask to boxwave customer service about this but if someone can answer my questions i'll be evry happy

Best regards,
tanguy

PS: Sorry if I'm not a DIYer but i've really no time at tis moment to make theses accessories by myself (if i had the technical competences, i guess i may have)
ANyway I'll enter the DIY club when i'd able to buy a bigger 1.8'' HD (40Gig monoplatter) and a more powerfull internal battery (2100mAh)... I already bought my T5 minitorx (from jeff eStore ) for this convenience..



Cheers;

4x 1.2 rechargeables will be fine for about 2 charges (Get 2300mAh types if you can). I even heard there are 1.25v ones available so if you can get those which will = 5v. Using 6v is probably a bad idea. Might fry it with prolonged use.

Shame you can't use standard alkalines as that would be useful if you are stuck with no place to charge from. Still at least this is something. I got a battery pack from Maplin on the cheap (Like £3!) that works great

[Tang]

UP! (i forgot how we say, i used to say BOUNCE but seems it's not the good word... )

[Mike]

Silly question, but: couldn't you use 3 "live" alkalines and one "dead" one (thereby getting 4.5v)? I've also heard of "dummy" batteries but wouldn't know where to get 'em.

[Astec]

Actually guys if you check it out there are lots of users using 4 AA alkalines, this works fine the player is designed to accept more than the stated voltage for safetys sake and the battery protection. There is no need for a dummy battery. Also alkalines in their nature deteriate in proformance, try a torch with them over time it gets dimmer, rechargables will give the same output for longer often till they near depletion. Plus the cost of 8 batteries and a charger is refunded in about 5 charges compared to Alkalines asthey are just disposed of.

[Tang]

Thanks astec, i wait for more advices but thanks for your post... Cheers!

[Tang]

Bump! (i remember "bump" that's it! )

[Tang]

Bump again... No electronician here to let me know what's the point with 6V or 4.8V instead of required 5V???

[NPswimdude500]

as astec told me previously....the player can handle 6v, but it uses 5v for safety reasons ? (i think). anyway, i am using 6v on my altoids pack, and its fine. 4.8v is close enough, but i'd go with 6v to make sure its really gets enough juice

EDIT: *link*

[Tang]

Okay NPS500 allright, thanks... I'wanna go for four 1.5V AA battery
