Complete Rechargeable System

The Streamlight PolyTac X USB delivers a complete rechargeable lighting system built around an 18650 battery with an integrated USB charge port. MULTI-FUEL innovation allows operation with the included rechargeable cell or standard CR123A lithium batteries purchased separately. TEN-TAP programming provides three selectable output modes including high, medium and low settings. High-impact nylon polymer construction with Rocky Stipple texture ensures a secure grip in wet or cold conditions.

Thermals Noise Power Draw

The integrated USB charge port on the 18650 battery enables convenient recharging from any standard USB power source without removing the cell from the light. Polymer housing naturally insulates the hand from temperature extremes during extended high-output operation. No cooling fan or active thermal management is present so operation remains completely silent. Power draw varies automatically with the selected TEN-TAP program to match output to runtime requirements.

MULTI-FUEL Battery Flexibility

This light accepts either the included Streamlight 18650 USB rechargeable battery or disposable CR123A lithium cells for backup power. Buyers who need a light that only accepts proprietary rechargeable packs should choose a different model. The dual-fuel capability ensures illumination is always available even when USB recharging is impossible. CR123A batteries are sold separately and not included in the package.

Questions about this item

How do I install the 18650 USB battery and what step do people often miss?

Insert the 18650 USB battery with the positive end toward the head, then charge fully via the integrated USB port before first use — skipping the initial charge is the common mistake.

What maintenance or replacement will the PolyTac X USB need later?

The 18650 USB battery will eventually hold less charge and need replacement; CR123A lithium batteries are also compatible as a backup power option.

What limit appears first during sustained use of the 88610?

The 18650 USB battery runtime depletes first during extended operation, especially on the high-output setting, requiring recharge or a spare battery.
