Earlier this summer we
wrote about Nitecore’s range of Leica-compatible USB battery chargers. There
was one major problem with the charger lineup at the time though: nothing for
the M10! Until now. At last, Nitecore has released a USB battery charger for
the M10 (and M10-P of course) which has a few cool features that users will
appreciate.
If you’re not completely
familiar with what makes these chargers so useful, I’d recommend taking a look
at my previous post, where I break down everything you need to know about
Nitecore USB chargers: Nitecore USB Chargers for Leica Batteries Offer MaximumFlexibility.
Features and Functions
As its name suggests, theNitecore USB Dual Battery Charger ULM10 Pro for Leica M10 & M10-P charges
two M10 batteries at once via USB cable. Unlike Nitecore’s other chargers which
feature a short, built-in USB cable that isn’t really long enough by itself for
much, the ULM10 Pro has a removable micro USB cord. This means you can use a
charging cable that is the right length for your particular need, if the 30
inch (12 cm) included cable isn’t ideal. I’ve been using the Anker PowerLine+Micro USB Cable with good luck, thanks to its super-durable construction. There
is a small channel in the back of the charger to seat the cable during use
which lets the charger sit flat.
Size and Weight
Compared to the “stock”
M10 charger that comes with a new M10/M10-P, the Nitecore ULM10 Pro is not too
much bigger. Here is a chart comparing the key dimensions and weight:
Nitecore ULM10 Pro Leica BC-SCL 5
Length 125mm 91mm
Width 70mm 69mm
Height 29mm 27mm
Weight 97 grams 110 grams
As you can see, the main
difference is that the ULM10 is 34mm longer than Leica’s charger, which makes
sense when you consider that it charges two batteries instead of one.
Thankfully it comes in a bit lighter. It would be nice to see Nitecore also
make a single battery charger for the M10, similar to their other models, so
hopefully that’s something we’ll see at some point.
Charging Capability
The ULM10 Pro features “QC
2.0” technology, which allows it to charge two batteries simultaneously when
attached to a compatible power supply. You’ll know you are getting the full QC
2.0 potential of the charger when “Quick Charge” shows up on the LCD screen.
Otherwise, one battery is charged at a time. As with Nitecore’s other chargers,
the LCD screen will tell you how much current is flowing into each battery,
which informs you how close you are to reaching the ULM10 Pro’s maximum current
of 1,200mA (one battery, QC 2.0) 800mA (two batteries, QC 2.0) or 700mA (either
one or two batteries without QC 2.0).
The “Quick Charge” icon
indicates you are getting the ULM10 Pro’s maximum charge input.
From my testing, a fully
drained M10 battery charges in two hours at 700 mA using the Nitecore USB WallOutlet Power Adapter. This is actually a bit slower than Leica’s own charger,
which performs the same task in about 1 hour and 40 minutes. That makes sense
when you read the specs on the Leica charger, as it has a maximum current of
1000 mA. Using an Anker USB Adapter that is QC 2.0-compatible, I was able to
reduce the charge time of one battery to 1 hour and 25 minutes from completely
dead to 100%. That is quite impressive, especially since it’s rare I let my
batteries get to 0%, which means charging from even 10-15% would take an hour
or less to full.
Final Thoughts
There is no doubt I’ll
never be bringing the standard M10 charger with me anywhere again. With its
ability to charge two batteries, provide detailed information about the battery
status and flexibility of charging sources, the ULM10 Pro will have a permanent
place in my M-system kit. Priced affordably at $60 (the same as Nitecore’s
other Leica-specific chargers), the ULM10 Pro is available now at Leica Store
