Review: "Omnipotent Power" PR-838 AA / AAA 4-channel battery charger

Thanks a lot for the offer Al!

Yep, I like the laptop a lot, great battery life. 0:) Just terrible speakers.

Dont worry i use an external set of speakers when i play games just sounds so much better then the ones on the lappy.

Personally, I couldn't wait 15hr - with eneloops anything that takes less than 2hr is doing harm to the cells - Sanyo recommend no more than 950mA charge current. I imagine most LSD cells are the same, but at least Sanyo tells you so. Some people tell you to charge them at up to 2A - but Sanyo ought to know about their own cells better than anyone else.

I have an 8A (15 minute) charger for AAs, but I prefer not to kill them that way. The cycle life of cells treated that way is minimal. The set of 2000mAh Energizers that came with it very, very occasionally get charged in it (usually in the car), but I don't normally need charged cells that fast and I do own more than 50 LSD cells which can be relied upon to work when required.

But it is a truly excellent name for a charger.

I know some chargers have a hard time knowing when to terminate the charge at low charge rates. Is it finishing the batteries at different times? You said it won't charge a battery that is already charged, so it must know something.

It does appear to be metering the charge correctly. For example yesterday when I started writing the review, I put a cheapo BTY and an Eneloop in the charger, both of them totally drained. After about 8 hours or so the BTY's indicator shut off. But the Eneloop was still going more than 12 hours later, but this morning it had also shut off. This seems logical in view of the drastically higher capacity of an Eneloop compared to the BTY cell.

Looks to me that the charger is doing its job, and for the price that you got them for seems well worth it.Cool

Not too bad eh? After all, it's a charger, and it charges my batteries. ;)

I really love the $5 price tag......you just can't beat that.

Hi! I found here

Great find.. I hope it has 4 single channel like the one used in this review.

I want to buy this charger for my father and my girlfriend but they don't ship to italy...F%£"()$/)!

Old thread,could be an advantage since I want to know if they have been reliable? Anyone?

I still use mine all the time, so problems so far! :) Definitely a budget success.

Thanks for the reply. Saw budget things were completely absent in the forum and ..........................

Can someone confirm “how long” does it take to charge 4 AA eneloops?

If you’d like, I can discharge 4 tonight and charge them on this unit…

That would be absolutely great man. Thanks

…and?

oooops sorry guys, totally dropped the ball on this one…I’m discharging four right now, I’ll report back…sucks being 50!

EDIT: I charged four rather new Eneloops for 14 hours and pulled them at that time, as the charging lights simply don’t work when you charge four cells. I then discharged them on my C9000, and they averaged around 900 mah…so…bottom line seems to be, this isn’t much of a charger for four cells. Seems to work well enough on one or two.

Thanks!
