Hi,
I’ve been looking for a compact (preferably one slot) USB charger that would be able to charge 15270 & 18650 & Nihm batteries. I’m quite new to chargers so not sure if it’s possible, considering it would be 1.2v, 3.0v and 3.7v, all in one.
If not available, then a 15270 & 18650 USB charger would suffice.
Thank you in advance

XTAR MP1S covers those sizes—by having what looks like 3 removeable spacers
Buster, you could read whatever is written on the batteries you want to charge and post that here.
And compare that with whatever charger you are considering, carefully. Make sure they match exactly.
> 15270/18650
15270 in particular might likely be a lithium-ion “3.0 v” — or might be “3.7 v” — and that takes two different charging voltages.
Some chargers have a switch to handle both. Others, most of them, only do one or the other.
But that size is the same size physically as CR123, which is a non-rechargeable battery.
18650 is almost certainly lithium-ion, and I’d guess more likely to be a 3.7v chemistry. But again you have to make sure.
“NiHM” — is probably “NiMH” — Nickel Metal Hydride — which is a 1.2 volt chemistry, and also requires a different charging method.
Those come in a lot of sizes.
And for charging lithium-ion cells you really need to know what’s what, and where and when and how to use and handle those.
Are you planning to use these in flashlights? What specific flashlight? Because some flashlights have electronics that protects batteries from over-discharge.
Other flashlights will drain a lithium-ion cell so far that it becomes dangerous.
If you’re saying “Hey, what’s the worst that could happen?” then you’re not ready yet.
Never heard of this charger. It looks like it might be an older model, as Xtar’s recent offering is actually the MC1 . However, the MC1 (and MP1S) doesn’t charge NiMH.
It’s available quite cheaply (about $6) from a number of US sources, so no need to wait an eternity to get it.
Thank You for the responses. I’ll have a look at the mp1s
After looking into things, looks like the MC1 supersedes the MP1S. Unless you prefer the design of the MP1S (with its spacers), the MC1 is a better way to go. It’s more compact, cheaper, and doesn’t have spacers to lose.
