TOPDON TS004 Pro review

What a night out with it looks like

TOPDON's store sells mostly automotive tools, and the TS004 line is its range of thermal monoculars. The Pro version steps up from the original TS004 to a 384×288 sensor and a 19 mm lens, with a 13.8° × 10.4° field, 50 Hz, 1x to 8x digital zoom, a 0.32-inch 800×600 OLED, 32 GB and five palettes.

By our calculator, the 19 mm lens on 12 µm pixels detects a person at about 1,425 m and recognizes a coyote at about 200 m (215 yd), the same as the AGM Taipan V2 19-384. TOPDON itself is conservative: 650 yd (594 m) to detect a person and 145 yd to recognize one. TOPDON also mentions a "TISR" image enhancement and a picture-in-picture mode with a 4x view in the center of the screen.

The 5,000 mAh built-in battery is rated at up to 10 hours of continuous use, which is the second longest in our list after its little brother. At 310 g (0.68 lb), tripod-threaded, it is one of the easiest thermals to carry all day.

The catch

Warranty and battery design. TOPDON lists 1 year of warranty on its US product page, against 5 years from AGM and RIX at similar prices. And the battery is built in: when it is empty, you plug a power bank into the USB-C port or you go home.

NETD is listed at <40 mK, against <25 mK for the RIX K3 and <20 mK for the AGM Taipan V2 384 models. On a dry, cold night you will not notice much; on a muggy August night, the cheaper K3 may show more contrast.

Great if…

• you want 384 resolution and a 19 mm lens for under $900
• you hate swapping batteries: up to 10 hours on one charge, by TOPDON figures
• you want something light enough to forget in a jacket

Skip it if…

• you plan to keep it five seasons: the warranty is 1 year
• you hunt cold nights far from a USB-C power bank (built-in battery)
• you care most about contrast on humid nights (<40 mK)

What TOPDON promises

Points taken from the official US product page.

• 384x288 sensor and a 19 mm lens for $899 (TOPDON US store, November 9, 2026)
• Up to 10 hours on the built-in 5,000 mAh battery, 310 g
• IP67 and 32 GB, but only a 1-year warranty

Sensor, power and recording

Sensitivity: <40 mK (TOPDON US spec table). Battery: Built-in 5,000 mAh, up to 10 h of continuous use (TOPDON figure). Photo and video recording to 32 GB of built-in memory.

Price and availability

US price checked on November 9, 2026 at the TOPDON US store: $899. The price at the store is the one that applies.

Buying advice

In stock at $899 on the TOPDON US store on November 9, 2026 (free shipping over $45 in the US). At that price, compare it with the RIX Pocket K3 ($799 on sale, 5-year warranty, shorter lens) and the AGM Taipan V2 19-384 ($1,195, same lens, sub-20 mK, two batteries).

The verdict

The TOPDON TS004 Pro is for the buyer who wants 384×288 detail, a 19 mm lens and a battery that lasts the whole night for $899: up to 10 hours on its built-in cell, IP67 and 310 g. It scores 8.7/10 overall and tops our compact ranking (9.1). What you give up for the price: a 1-year warranty, a battery you cannot swap and a sensor rated <40 mK.
