ZeroHour Relic XR2

This is a super-bright tactical flashlight, comfortable in the hand, and compact. It’s not too heavy to carry around as it has been developed to fit on a weapon and a bike as well. It’s not just the convenience of having such a useful tool to carry in a bag or on your belt; the charging capabilities the ZeroHour RELIC provides will have it replacing every other power bank you need to carry, and this saves on weight and space.

The packaging includes a drawstring pouch, charger, and extra accessories. The Type C power bank charges both iPhone and Android, making this a flashlight with multiple uses besides simple illumination. Speaking of lighting, the XR2 packs a powerful 2,000 lumens – making it a ferocious tactical flashlight – capable of blinding anyone at any meaningful proximity at night.


The IPX8 rating is one of the optimum valuations a tactical flashlight can receive when being tested for waterproofing and submersion capabilities. See our previous review to find out more about how this testing is done.

The XR2 is a good looking piece of equipment, constructed with aircraft-grade aluminum and capable of an amazing 2,000 lumens output due to the Cree-XHP35-Hi-Intesity LED. This particular ZeroHour model has effectively doubled the luminosity power of the XR and the XD. This progression is in keeping with the continuation of ZeroHour’s dedication and commitment to only using the finest design materials available in its class. The design also allows easy access to the variable control ring which features maximum flexibility when you need to choose a level of brightness (0 all way up to 2,000). Additionally, there is the option to click to access the XR2 model’s preset modes:

  • 10 lumens
  • 2,000 lumens
  • Blink
  • Strobe

Type-C USB Rechargeable and Portable Charger

If you need an extra backup power boost, the 3,100-mAh Samsung high-drain IMR batteries each XR2 flashlight model features can provide another full charge for any device. Unscrew the center ring to access the port to charge up your devices with the USB or recharge the flashlight itself. If you haven’t switched up to USB-C capabilities yet, ZeroHour has included a USB-A cable in the package, and you can use this for backward compatibilities.


1 x 18650 high-drain battery 20A-IMR will provide 3,100-mAh of power – enough for one to two full charges for most of your smart devices. The battery cells are manufactured from one of the most trusted names in electronic power, Samsung. The XR2 can fully charge or recharge most devices with a USB port, but the Samsung-S8’s 3,500-mAh won’t be charged fully.

You can recharge the XR2 using the USB-C port and the USB-C/USB-A cables that come supplied in the package. Any standard wall socket that you use to charge your devices will recharge the ZeroHour RELIC XR2 as well. The model with going into “Breathe” mode and glows intermittently if the power cuts out when it is charging, making it easier to locate.

  • Battery charge will last for 100hours running at 25 lumens (low)
  • For 1.2 hours when running at full capacity 2,000 lumens (high)
  • Variable brightness strength means variable running time
  • Overheat protection circuit steps it down to 1,000 lumens

Pros & Cons

The XR2 design makes it very versatile. It was no small thing to integrate the high power LED with a high standard battery that also routes to a portable charger. The XR2 design is patented, and no other tactical flashlight on the market can be compared to it. The incorporation of a tail cap switch that has a “momentary-on” click setting, plus the rolling ring and removable clip ensure optimum high functionality.
