Hi All,

Any of you guys know of a portable charger power bank
that uses nickel metal hydride rather than a lithium
battery?

Many thanks,
-T

In an effort to help you, I looked up some recent reviews of power banks,
and most of them, as you likely knew already, are _not_ Ni-MH power banks.

There are many "individual" AA and AAA Ni-MH battery chargers of course,
but you're looking specifically for a portable USB-C power bank, right?

Seems strange that it's hard to find a Nickel Metal Hydride portable power
bank - but that first pass check didn't find any reliable reviews for you.

Who knew it was so hard to find?
Not me.

I doubt that there are factory new PBs that use this very old
technology. Energy density and durabilty are inferior.

What is the reason for this?

I was looking for a power pack for my wife's tablet and
did not frighten her. So far Lithium polymer is the
best, but Ni-MH would be even better.

If correctly used this is and never was an issue. The probability is not
much idfferent from zero.

All powerbanks have management circuits which are designed to prevent the
cells getting into a dangerous state where fire is risk. Some are better
designed than others, so it's good to buy a high quality pack (ie not an
Amazon brand made up of Scrabble letters, or from Aliexpress).

After all, your phone has a lithium battery in it, and that's in the same
situation as a powerbank.

I very much doubt you'll find powerbanks with NiMH. Best case is to find a
portable phone charger that takes AA batteries, and carry your own NiMH
batteries and charger.

Also a phone battery is about 10Wh, the average AA NiMH is 3Wh, so you'll
barely get more than a single charge out of a set of 4xAAs.

There are a few, mainly by GP. As far as I could tell, though, none
seemed to have a USB-C connection. Mini and perhaps micro-USB, but not
USB-C.

After two fires, city transport in Madrid has prohibited portable
electric vehicles inside buses and Metro (underground railway). This
breaks greatly the advantage of those vehicles, but it is true that
there have been recent fires, the one on the Metro stopping service
totally in one of the lines for hours.

The airline in which I flew this summer prohibits all kind of batteries
in the baggage that goes into the cargo hold. Even standard AA batteries
or button cell (watch) batteries.

They have to be manufactured perfectly or the
tendrils grow and kaboom. There is a lot of
temptation to cut corners to squeeze and extra
1/2 cent of margin out of them. Dell and
Samsung paid a dear price for that foolishness.

The problem is that customers do not know when they are buying dangerous
batteries. As it is not viable to prohibit whatever batteries from being
sold and used, the only protection is to prohibit battery powered
devices in critical areas.

We would need some organization examining all batteries and then
stamping some seal of safety. All other batteries should be removed,
banned, fined.

It occurs to me. A discharged battery, stored somewhere, is dangerous?
Can it catch fire? I think not, but :-?

Because I'm wondering about my old disused phones and devices in
cupboards and boxes.

Closer to home for me. My daughter had a charging scooter battery catch fire
in her garage while she and family were asleep. Fortunately a smoke alarm
woke them. The fire department was able to contain the fire mostly to the
garage though it did burn through one inside wall. The repairs to the house
cost thousands but it could have been much worse...

Dunno. The wife's iPhone battery swelled up like a balloon causing the case
to pop open some years back and it wasn't a cheap phone...

Now that I remember, at least one of my cameras recommends that when
storing the batteries for long time unused, do so uncharged.

Of course, this is a problem if you keep the camera in a cupboard and
expect to be able to use instantly if the occasion arises.

Probably because it's considered inhumane to make the rats keep
building them.

Depending on the type, over time if disposed in a landfill it can
leak heavy (poisonous) metals into the groundwater.

My Amazon HDX 7" Kindle reaches its tenth year or use this month. I
use it for at least half an hour every day. When the battery gets
under 10% I plug it into the charger, and I'm not very prompt about
unplugging. I guess Amazon really made those suckers bulletproof. (I
don't know what kind of battery it has.)

Wow -- glad it wasn't worse! I asked my bike shop before I bought it,
and they said the riskiest time for fire is while it's charging, or
while stored in high heat. I wonder about that fire Carlos reported
in the Madrid Metro -- is it super hot in those trains?

My ebike lives in my attached-but-uninsulated garage, but when I'm
not actually riding I remove the battery and bring it into the house
so it's not exposed to 100° heat. I charge it in the house, and check
the indicator periodically so that I can take it off charger
promptly.

I've read that laptops should be stored with 50% to 80% charge, and I
just assumed it would be the same for cameras. Luckily my only
cameras are part of phones or laptops!

My phone (Galaxy S10+) can be set to only charge to 85%. But I prefer a
full charge to start the day with (I'm an overnight charger) because you
never know when you'll need it. So far at 4+ years I've not NOTICED any
battery problems (crosses fingers)...
