Nitecore UI1 Charger Review

Nitecore sent me a pre-release copy of their new single bay charger.  This is the Li-ion only UI1.  It’s a simple charger; read on for some photos and a bit of charge testing!


Official Specs

There isn’t an official listing for this item yet – but have a look at the pdf manual below for the full specifications.

Price

No product listing yet = no price.  Sorry!

Short Review

This isn’t a bad little charger, but with no powerbank feature, and only charging at 0.8A, the usefulness may be limited.

Manual and Packaging

I don’t have any packaging, but here’s the manual:

UI1_UM_EN

So new that the manual isn’t even a pdf!

What’s Included

The charger and cable were included in my package.  Probably the only addition in the retail package will be a manual.

Build Quality and Durability

The UI1 is on par with other single bay Nitecore chargers.  The back is nicely imprinted with all the applicable cells.

The ends don’t have much going on – just a micro-USB input.  There are no output features (this is not a powerbank.)

Size

Dimensions:  122.5mm × 29.2mm × 32mm

Weight:  40.5g

This isn’t the smallest single bay charger.  It’s not even the smallest single bay charger with USB output.

Power

The UI1 is powered by micro-USB, which connects at the end of the device.  A cable is included, and it’s a nice cable indeed.

This charger will charge many sizes – from 16340 all the way up to 21700 in length and 26650 in size.  Essentially any Li-ion cell that fits in here will charge.

I’ve run a couple of charge tests on an 18650 cell.

Charging proceeds as it should.  The charge rate is around 0.8A

User Interface and Operation

There are no buttons on the UI1.  Just put the cell in, and off it’ll go.  The charger will detect if a 0V cell needs correction, and there is reverse polarity protection, too.

During charging, blue LEDs flash to represent the level of charge.  Three solid LEDs indicate that the cell is fully charged.

Conclusion

What I like

  • Good set-it-and-forget-it charger
  • LEDs adequately display the information

What I don’t like

  • No powerbank feature
  • Low 0.8A charge rate

Up Next

I’m going to sneak in a Fun Fund Friday tomorrow!  Something I’ve been putting off, but will possibly be interesting to at least one user out there!
