Keychain flashlights aren’t overly bright, they’re not going get you through the apocalypse, and, for many, they’re not even a crucial part of everyday carry. That said, they are perfect in a pinch, better than your phone’s so-called flashlight, and they practically disappear on your keychain.

Keychain lights certainly have a place in this world and there’s no shortage of great options, especially as LED and battery technology advance and shrink. Below, you’ll find 10 of the best USB rechargeable keychain flashlights as of January 2019.


Nitecore TUP

The Nitecore TUP is the newest, largest, and brightest torch on this list, and it’s undeniably the most innovative. The TUP features an LED display readout that shows the brightness level and a countdown timer for the battery life.

The Nitecore TUP also uses Nitecore’s traditional dual-side switch interface with two lockout modes, a removable clip, and micro USB recharging via a port along the side of the light. The biggest drawback to the TUP is its size, as for many it will be too large to tote on a keychain.


Nitecore TUP key features:

  • Price: $64.95
  • Interface: Dual side switch, 5 brightness levels, LED display readout
  • Ultralow: 1 lumens @ 70 hours
  • Low: 15 lumens @ 19 hours
  • Medium: 65 lumens @ 9.75 hours
  • High: 200 lumens @ 3 hours
  • Turbo: 100 lumens @ 15 minutes
  • Water resistance: IP54
  • Weight: 1.88oz/53.2g
  • Dimensions: 2.77in (70.3mm) x 1.16in (29.5mm) x 1.03in (26.2mm)
  • Battery: Internal 1,200mAh, micro USB rechargeable




EverBrite LED Keychain Flashlight

The EverBrite LED Keychain Flashlight is different from most of the other lights in this list. For starters, it’s the only one with an RCR123A battery, which means it could pair really well with another, larger light that takes the same battery. At the same time, despite the larger battery, its max output is just 160 lumens. The upshot of that lower max output, however, is its runtime — two hours at max brightness.

The EverBrite keychain also has an interesting interface. While it’s a twist function torch, screwing down the cap doesn’t make the light brighter. Instead, each time you twist to turn the light on, it will advance through the four different modes — low, medium, high, and strobe.


EverBrite LED Keychain Flashlight key features:

  • Price: $18.49
  • Interface: Twist, four modes
  • Low: 30 lumens – 10 hours
  • Medium: 100 lumens – 4 hours
  • High: 160 lumens – 2 hours
  • Water resistance: IP65
  • Weight: oz (g)
  • Dimensions: 2.5in (63.5mm) x 0.8in (20.6mm)
  • Battery: Removable RCR123A, micro USB rechargeable




Nitecore TIP

With a slim, rectangular shape, the Nitecore TIP is a classic form factor for a keychain flashlight. It harkens back to the old button cell-powered keychain lights you used to find at the hardware store. This is just like those … on steroids. You get Nitecore’s typical two-button interface, instant access to turbo mode, and a maximum brightness of 360 lumens. All of this is packed neatly in a very compact and ergonomic form factor.

The Nitecore TIP also comes in an array of colors and has an adjustable clip, so you can opt to clip this light inside your jean pockets, to a hat, or hang it from your keys.


Nitecore TIP key features:

  • Price: $36.95
  • Interface: Dual side switch, four brightnesses
  • Low: 1 lumens – 46 hours
  • Medium: 35 lumens – 6.5 hours
  • High: 150 lumens – 1.5 hours
  • Turbo: 360 lumens – 30 minutes
  • Water resistance: IPX8
  • Weight: 0.83oz/23.5g
  • Dimensions: 2.39in (60.8mm) x 0.96in (24.5mm) x 0.54in (13.8mm)
  • Battery: Internal 500mAh, micro USB rechargeable




Nitecore TINI Cu

If the Nitecore TIP is just a hair too big for your keychain, you might consider its smaller cousin, the Nitecore TINI. With the very same interface, the TINI is, well, smaller. It also looks like some nautical tool for deep sea diving (please don’t take it diving, its water resistance rating is only IP54).

If the design of the TINI isn’t enough, its lumen ratings should push you over the edge. At its max, the TINI can pump out 380 lumens for up to 15 minutes. Given its size, that’s rather impressive. At just 1 lumen, you can squeeze up to 60 hours out of the tiny light.


Nitecore Tini CU key features:

  • Price: $31.95
  • Interface: Dual side switch, 4 brightness modes
  • Low: 1 lumens – 60 hours
  • Medium: 38 lumens – 4 hours
  • High: 145 lumens – 1 hour
  • Turbo: 380 lumens – 15 minutes
  • Water resistance: IP54
  • Weight: 0.76oz (21.5g)
  • Dimensions: 1.7in (43.2mm) x 1in (25.4mm) x 0.45in (11.4mm)
  • Battery: Internal 280mAh, micro USB rechargeable




RovyVon Aurora

The RovyVon Aurora flashlight is no stranger to the Best Damn EDC. We’ve extensively covered it in several videos and roundups. It’s easily one of our favorite lights of 2018, and it’s as if RovyVon pumps out a new version of the popular Aurora every week. The massive output — up to 550 lumens — of the Aurora is its standout feature. It’s incredibly compact, comes in polycarbonate, stainless steel, anodized aluminum, titanium, and a luminous body. Select versions of the Aurora also feature side lights in red LED or UV light.

The thing to note about the Aurora is its runtimes. With such a high maximum output, the Aurora can only output the impressive 550 lumens for up to two minutes before it drops down to 60 lumens. Unlike most of the other lights on this list, the Aurora features a removable and adjustable clip.


RovyVon Aurora key features:

  • Price: $25-$70
  • Interface: Side switch, four or more modes
  • Low: 10 lumens – 60 minutes
  • Medium: 65 lumens – 40 minutes
  • High: 550 lumens – 2 minutes (65 lumens)
  • Water resistance: IP65
  • Weight: 0.7oz/20g
  • Dimensions: 2.16in (54.8mm) x 0.57in (14.5mm)
  • LED Cree XP-G3 or Nichia 219C (350 lumens)
  • Battery: Internal 130mAh, micro USB rechargeable




MecArmy X3S

The X3S is just one of many of MecArmy’s keychain flashlight offerings, like the X1S, X2S, and X4S. The entire family of lights is made up of tiny twist lights that are just under two inches in length and are made of materials like copper, titanium, aluminum, or stainless steel.

To charge the MecArmy X3S (and its compatriots), simply untwist the cap entirely and plug in a micro USB cable into the port just above the threads. As a safety feature, the cap (holding the LED) is not entirely removable. You can also remove the tail of the flashlight to replace the internal 10180 battery.


MecArmy X3S key features:

  • Price: $24-$50
  • Interface: Twist, two modes
  • Low: 8 lumens – 6 hours
  • High: 130 lumens – 30 minutes
  • Water resistance: IPX8
  • Weight: 0.63oz (18g)
  • Dimensions: 1.83in (46.4mm) x 0.58in (14.8mm)
  • Battery: Removable 10180 (100mAh), micro USB rechargeable




Klarus Mini One

The Klarus Mini One is remarkably like the MecArmy X4S in that they’re both made of aluminum and they share the same interface, nearly the same dimensions, and virtually all features. The biggest differences are in appearance, such as design cues and dimensions — the Mini One is slightly smaller. And price — the Klarus Mini One is just $19.99.

Like the MecArmy, the Klarus Mini One recharges via a micro USB port underneath the cap, which can’t be fully removed. And if you unscrew the tail of the light, you can remove the internal 10180 battery. However, the Mini One does not feature a lanyard hole on the tail. Instead, it has just two holes for split ring attachments.


Klarus Mini One key features:

  • Price: $19.95
  • Interface: Twist, two modes
  • Low: 8 lumens – 5.25 hours
  • High: 130 lumens – 24 minutes
  • Water resistance: IPX8
  • Weight: 0.56oz (16g)
  • Dimensions: 1.73in (44mm) x 0.59in (14.9mm)
  • Battery: Removable 10180 (100mAh), micro USB rechargeable




Fenix UC02

Like most other USB rechargeable keychain lights, the Fenix UC02 features a twist interface and two brightness modes. It also holds a 10180 battery that can be removed by unscrewing the tail cap. The major difference in the UC02 from lights like the MecArmy and Klarus is that the cap must be fully removed to reveal the micro USB port for charging.

Thanks to a textured surface, the stainless steel UC02 is more grippy than other keychain flashlights, but it also comes in a smoother aluminum version. It also features a lanyard hole on its tail cap.


Fenix UC02 key features:

  • Price: $24.95
  • Interface: Twist, two modes
  • Low: 10 lumens – 3 hours 50 minutes
  • High: 130 lumens – 25 minutes
  • Water resistance: IP68
  • Weight: 0.65oz (18.4g)
  • Dimensions: 1.7in (43.2mm) x 0.55in (14mm)
  • LED: CREE XP-G2 S2
  • Battery: Removable 10180 (80mAh), micro USB Rechargeable




Olight i1R EOS

The Olight i1R EOS is the fan favorite. Maybe it’s because it’s smaller and cheaper than most with most of the same featured. Whatever it may be, the Olight i1R EOS completely disappears on the keychain thanks to its small footprint and aluminum construction. It’s also a twist interface with two brightness modes and comes with a split ring attached to the tail of the light.

The i1R EOS has a fatal flaw, however. The battery is internal and non-replaceable. And to recharge the light, you have to completely remove the cap.


Olight i1R EOS key features:

  • Price: $16.99
  • Interface: Twist, two modes
  • Low: 5 lumens – 7 hours
  • High: 130 lumens – 20 minutes
  • Water resistance: IPX8
  • Weight: 0.42oz (12g)
  • Dimensions: 1.61in (41mm) x 0.55in (14mm)
  • LED: Philips LUXEON TX, TIR Reflector
  • Battery: Internal, micro USB rechargeable




Maratac Peanut

The Maratac Peanut is easily the smallest and lightest on this list. In fact, for it to be a USB rechargeable flashlight, it’s unbelievably small and bright. Despite its smaller footprint, it’s got a brighter output than other micro flashlights at 145 lumens.

There is a trick to how Maratac was able to make the Peanut so small and, unfortunately, it’s the worst part of the light. In order recharge, you not only have to remove the cap holding the LED, but you also have to screw on a different attachment that houses the micro USB port and all the recharging circuitry. But if you’re after the smallest and brightest flashlight money can buy, the Maratac Peanut is it.

Maratac Peanut key features:

  • Price: $45.99
  • Interface: Twist, two modes
  • Low: 12 lumens – 6 hours
  • High: 145 lumens – 25 minutes
  • Water resistance: IPX-7
  • Weight: 0.38oz (10.7g)
  • Dimensions: 1.29in (32.8mm) x .52in (13.2mm)
  • LED: Cree XP-G2 S4, orange peel reflector
  • Battery: 10180 (70mAh), micro USB Rechargeable
