Sofirn SC28 Review: Big Battery, Bright Output, But One Big Miss

Introduction

The Sofirn SC28 is a large, rechargeable flashlight built around a 21700 battery and a USB-C charging port. With up to 2,800 lumens on tap, it promises serious output and long runtimes. The question is whether the rest of the package lives up to the numbers, and the answer there is more complicated than the spec sheet suggests.

Who This Product Is For

This is a flashlight for someone who wants a bigger, longer-running light rather than a compact everyday carry piece. The 21700 battery typically holds around 5,000mAh, which is a substantial step up from most smaller cells and translates into noticeably longer runtimes. The trade-off is weight and bulk: this is a big flashlight, and it will not suit everyone’s pocket or bag.

If you mostly want a light that stands up on its tail, throws a lot of light, and recharges over USB-C, the raw ingredients here are appealing. The catch is in how you actually get that light out of it, which we will get to shortly.

Design and Build

Out of the box, the SC28 makes a solid first impression. The mid-body has really good texture for grip, the bezel features a lightly granulated, not overly aggressive crenulation, and the light includes fins for heat dissipation. It also tail stands, which is handy for working hands-free.

The optic is one of the more interesting choices here. It uses a spherical-style lens with a honeycomb pattern that produces a very dispersed beam, softening all the way out to the edges. It is a genuinely pleasant beam profile that avoids harsh hotspots.

Grip near the head is less convincing, since there is nothing stopping your hand from sliding up, though it is still not difficult to hold.

User Interface: The Weak Point

This is where the SC28 stumbles. It uses a reverse-click tail switch with a generic interface. To change modes, you have to half-press repeatedly to cycle through brightness levels, then press fully to select. Turning it back on brings up whatever mode was memorized last.

In practice, that means no quick access to turbo or to moonlight unless the light happened to be saved in the right mode. In a dark room, you can end up blasting 2,800 lumens when all you wanted was a faint glow, blowing out your night vision in the process.

The deeper issue is that a tail switch only earns its place if it gives you the brightest output immediately in one full press, especially in a panic moment. Sofirn already makes plenty of side-switch lights that do this well: hold for moonlight, double press for turbo, single click for the main modes with ramping or stepping. Against those options in the same brand’s lineup, the SC28’s interface feels like a step backwards.

Things to Consider Before Buying

There are real positives here. Output of 2,800 lumens is genuinely bright, the 21700 battery delivers long runtimes, and the diffused honeycomb beam is comfortable to use. As is typical for the brand, the value proposition is strong, and the price is expected to come in well under forty dollars, which makes it hard to call it outright bad.

The rechargeable USB-C port also removes any fuss over external chargers, which is convenient for a light of this size.

But none of that fixes the interface. If you cannot get to turbo in one click, or drop to moonlight without cycling through maximum output, the flashlight works against you at the worst moments. For a large tail-switch light, that is a fundamental miss.

Buying Advice

Sofirn makes many excellent flashlights with better side-switch interfaces, and those are the ones worth your money first. If you are set on a large 21700 light, look elsewhere in the lineup before settling on this one. If budget is your only concern, the SC28 still outperforms plenty of worse flashlights from other brands, but it falls short of what this brand has proven it can deliver.

Conclusion

The Sofirn SC28 gets the hardware right: big battery, high output, pleasant beam, and honest value. The generic reverse-click interface undermines all of it, and for that reason it is easier to recommend skipping this one and choosing one of the brand’s better side-switch lights instead.
