We recommend the UltraFire M21 Mini for everyday carry and small camp tasks where a compact multi-function tool is more useful than a dedicated high-output flashlight. Price $15.99. The partner record does not list eligibility for this product. Best for campers who want a light, clip, magnets, and auxiliary work light in one small carry tool.
A pocket light with a COB work light and electric ignition coil.
We recommend the UltraFire M21 Mini for everyday carry and small camp tasks where a compact multi-function tool is more useful than a dedicated high-output flashlight. The front spotlight is listed at 300 lumens, while the side RGB/COB light has seven modes including white, red, red-and-blue flash, and several color patterns. A covered electric ignition coil is built into the same 80mm body. The three-position selector separates the spotlight, side light, and coil, and the reversible clip, two magnets, and keyring slot give it several carry options. The built-in battery charges over USB-C and the body carries an IP54 dust and splash rating.

- Several functions fit in a small body
- The carry options are flexible
- The battery recharges by USB-C

Who should carry the M21 Mini?
It suits people who want a pocket-size light for inspections, short walks, and close camp chores, plus an auxiliary color light. It is not the best one-light choice for a long trail or a large campsite.
Three separate functions
The front spotlight is listed at 300 lumens. The side RGB/COB light offers seven modes, while a protected electric coil provides a third utility feature. The main selector switches among these functions.
Use the carry features that fit the task
Clip the light to a pocket or cap brim, use the magnets on a suitable metal surface, or attach the lanyard and key ring. The maker lists IP54 dust and splash resistance, not immersion protection.
Plan around the missing runtime data
Charge it before a trip and carry a dedicated headlamp when reliable hands-free light matters.

Why we like it.
Several functions fit in a small body
The front spotlight, RGB/COB side light, and electric ignition coil bring different utility functions into an 80mm body weighing 36.7g.
The carry options are flexible
A reversible clip, dual magnets, keyring slot, and lanyard let you carry it on clothing or attach it to nearby metal for hands-free use.
The battery recharges by USB-C
The built-in battery and included cable avoid carrying a separate replaceable cell for this light.
A few things to consider.
It is not a substitute for a headlamp
A clip and magnets can help with nearby tasks, but the product is not a headband light. Keep a dedicated headlamp for hands-free movement on a trail.
The auxiliary output is not quantified
UltraFire lists seven side-light modes but no lumen output or runtime for them. Do not assume the COB panel can replace a lantern.
The ignition coil adds a specialized function
The covered heating coil is unusual in a keychain light. If you only need illumination, a simpler single-purpose flashlight avoids carrying a feature you will not use.
