Sofirn IF23 Review: A Dual-Light Emergency Flashlight That Doubles as a Power Bank

Introduction

Some flashlights try to do one thing well. The Sofirn IF23 tries to do several, and for the most part it succeeds. On the table it looks like a fairly standard handheld light, but it packs a front-facing spotlight, two sets of side emitters, a strong magnetic tail, waterproofing, and reverse charging into one body. That combination makes it one of the better emergency or home flashlights you can put in a drawer or a car.

Who This Product Is For

This is not an everyday-carry flashlight by any stretch. It is built for the house or the vehicle: something you reach for during a power cut, when working under the hood of a car, or when trying to get someone’s attention. It runs a nice swath of uses and works well as a complement to the smaller lights you may already carry.

Standout Features

The IF23 uses two different sets of emitters. The front emitter tops out at 4,000 lumens and steps all the way down to 1 lumen, while the side panel runs from 1 to 500 lumens. Add a genuinely strong magnetic tail that easily holds the light upright against its own weight, a USB-C charging port under a well-fitting silicone cover, and an IPX7 rating that makes it fully waterproof, and the hardware side is very well sorted.

Reverse charging is the feature worth highlighting. The IF23 essentially works as a waterproof power bank. With its 5,000 mAh 21700 battery, it can transfer roughly 80 percent of its rated capacity, meaning it should fill up a phone around 4,000 mAh after losses. In many situations you may not need a flashlight but you do need more juice, and storing that in your flashlight makes a lot of sense.

User Interface and Light Modes

The interface is where things get complicated. From off, a single click turns on the front LED and cycles through low, medium, and high; a double press jumps to Turbo for the full 4,000 lumens. The side light turns on with a double press from off, cycles the same way, and its Turbo delivers 500 lumens. Double presses from there cycle through tactical strobe, SOS, and Beacon, with Beacon being a sensible low-drain distress signal for extended use.

The frosted lens on the side panel distributes light remarkably well, evenly enough that it could plausibly serve as a small video light or a card-playing lamp. Holding the switch for one second activates Moonlight mode, which remembers whether the front or side light was last used. It is a clever design that avoids requiring half a dozen presses.

A triple press reveals a bonus: the center strip of multi-colored emitters, which can cycle through a range of hues by holding the button. There is no obvious practical application for it, but it is a genuinely fun extra. Lockout is handled with a four-press sequence, and even while locked the light still works in momentary mode, which is exactly how it should be done.

Things to Consider Before Buying

The only real drawback is learning curve. This is not a light to hand to someone who has not used it before, and even regular users will take time to learn all the ins and outs. The hardware makes the interface about as good as it can be given what the light can do, but it still takes getting used to.

Also note that reverse charging requires a USB-C to USB-C cable; the included cable will not do it. The pocket clip is present but feels unnecessary for a light this heavy, and there is no headband, so headlamp use does not make much sense. It ships with a lanyard and spare O-rings.

Buying Advice

If you want a bag light or an emergency light that covers spotlight, flood, signaling, and phone charging in one waterproof body, the IF23 is a very strong pick. Sofirn is known for aggressive pricing, and the brand runs frequent sales through its own store and ships from a US distribution center, so it is worth checking both the Amazon listing and the manufacturer’s site before buying.

Conclusion

The Sofirn IF23 is a home run for home and vehicle use. Strong magnetics, useful dual emitters, sensible emergency modes, and reverse charging come together in a light that is hard to fault once you have learned its interface. If you can spend an evening with the manual, you will be rewarded.
