Thanks ChibiM. Done a bit more research and does look it is smart in that current is varied “depending on temperature and battery status”. I’ve edited my post above.
I don’t really need another charger but the powerbank feature is interesting and looking to put all the Tones I’ve accumulated to good use.

I have it.
It is totally smart.
But with old batteries (high internal resistance) it has a bit of problem.
When using as charger… It reports them as “batteries should be replaced”.(but it charges them… Other chargers simply refuse to charge them)
When using as powerbank… The output current is not 1Amp… More likely 500-700mA.
If you want full 1Amp output, you must use young/new batteries with low internal resistance.
With my old eneloop XX( with a few cycles) it shows that behaviour.
With my white eneloop (with many cycles) it works like a charm. No yellow led indicating batteries should be replaced and full 1Amp output

Ah good to hear! Shame to hear about the output but I guess I could just keep some new cells with me if I need to use it as a powerbank.
Did you look into the little flashlight attachment?

Based on the charging time table, it looks like those current values apply if you charge all 4 cells simultaneously. If you only charge 1-2 cells, charging times are cut in half, which would indicate that current is doubled, so a single AAA cell would be charged using 0.5A current.

What flashlight attachment? I am not seeing anything on that page, unless I missed it or my ad blocker got it.
Are you referring to something like this?

Hmm ok, makes sense. I’ll take another look through the manual.
Here’s the attachment which I mentioned and also ChibiM posted a few pages back.
There’s probably nothing special about it and a 3rd party USB light would probably be just as good or even better.

Any way to get that led light attachment? Can be purchased separately?
EDIT: the led usb light attachment is included only in japan version. Eu version dont include

Correct, only available in Japan as far as I know. Still a fun attachment. I have one personally.
XTAR sell a little USB light as well, if it’s any use:
XTAR UL1-120 EDC Light-ShenZhen XTAR Electronics Co., Ltd-· One LED for a four-color light
· One button for seven modes
· Wide application
· Strobe mode for self-protection
· USB port, plug and use
· USB metal hose for 720° light control
·...
I don’t have one myself, though, so that’s all I know.

All aneloop and nihm type batteries are overrated and overhyped if you need run device with minumum 1.5 voltage battery. I’m really disappointed.

NiMH are nominal 1.2 V and they excel for their purpose.

How many devices out there require 1.5V minimum?
Most standard or alkaline batteries do not stay at 1.5V very long. For those applications, something like Tenavolts (1.5V Li-Ion) may be best.

Not many that I have personally, but my current clamp ( uni-t 210E) starts reporting wrong numbers when the cells are under ~1.45V, it’s really bad. My meteo station modules seems to have a high cut off, although not as bad.
I’m wary of the potential self discharge rate of a li-ion cell coupled with a voltage converter, but more importantly they are extremely expensive.

Yes. Luckily I bought some on sale for under $12 for 4 AA Tenavolts and a charger. That’s about the same price as 4 eneloops.
I am using them in one of my universal Harmony remotes.

If that sensor is going to sit outside, exposed to significant temperature extremes, your best bet would be lithium primary.

One of my old Canon digicams would show low battery almost immediately (maybe take a half dozen photos first, that’s about all) with any NiMH. I put some lithium primaries in and they were good for a couple hundred pics.

Some devices don't really like NiMH batteries because of their voltage, but that doesn't mean they still are one of the best rechargeable NiMH batteries on the planet..

New fake Eneloops spotted in India this time. Thanks to a reader named Shashi, who tipped me.
What do you think looks weird on this packaging?
