Looking for a 2-bay charger with diagnostic display, like UM2 but better

I’ve been using a Nitecore UM2 for the past 2 years and was pretty happy with it. I like the way it works and the info display provided. The movable prongs are better than on the i4, but still a little shoddy. Still, the thing was working fine. The big drawback is Micro USB. And… as I discovered, the port is a weak point. Mine broke off, separated from the PCB.

While I’m going through the motions of figuring out if I’m going to fix this thing, I’m wondering if there’s a good alternative out there in the market. I paid $20 for my UM2 and wouldn’t mind going up to $30 if I’m getting some quality improvements.

I definitely want a diagnostic display (not just LED’s), showing the charge level and the charging rate. I wouldn’t mind a test mode to show mAh capacity, but it’s not a necessity. I’d prefer USB-C and also a lid that closes over the cells (the UM2 is totally naked). Is there one or two chargers out there that might fit these requirements? Oh yes, and it should support 16340 up to 21700 and 26650.

I found it. The Fenix ARE-D2.

The contender was the Nitecore UMS2. This one looked to be more desirable than the UM2, with variable control over charging current (up to 2A). And frankly, at $20 shipped from a reputable eBay seller, not a bad deal.

FENIXUSA20 is the current code over at Fenix-Store, for 20% off. Free shipping, no taxes, for USA purchases. I got the ARE-D2 for $21.50. The reviews are really good. The UMS2 has mixed reviews… and the build quality looks very similar the UM2, which did not impress me.

Btw, there is a Fenix ARE-A2 that is very closely priced, just $3 cheaper than the D2. And, it has a maximum charge rate of 1A. I couldn’t find any other difference, so I think the D2 is definitely worth it.

The D2 is still a micro USB, so you could probably find a faster charger. I think ‘c-to-c’ is usually considered faster, for example. I don’t know enough about chargers to recommend one for your specific needs though.

Yeah, I hadn’t seen a 2-bay charger with USB-C for under $35. Speed isn’t super important to me, because fast charging can wear down a battery faster. So most of the time I prefer to go slower, reserving faster on rare occasions (short on time). I’m hopeful that the Fenix build quality will be better, so the port won’t be as fragile as on the UM2.
