Cordless COB Work Light with Power Bank

The WARSUN Y39 is a portable LED lamp built around a 40 W COB panel that delivers up to 1500 lumens. It runs on an integrated 3000 mAh rechargeable battery and offers three output levels plus a strobe mode. A blue TPR-reinforced shell and IPX4 splash resistance make it suitable for outdoor job sites, camping or emergency use.

Magnetic Mount and Hook for Fast Setup

A strong base magnet secures the light to any ferrous surface such as a vehicle chassis or tool cabinet, while a built-in hook allows hanging from tent poles, branches or a wall-mounted screw. Charging uses a standard Micro-USB cable; no driver installation or pairing is required. The only common issue is forgetting to recharge the internal cell before a long shift.

Micro-USB Charging Limits Runtime and Device Support

The 5 V Micro-USB input caps recharge speed, so a full top-up takes several hours and cannot be accelerated with higher-voltage adapters. The power-bank function shares the same 3000 mAh reservoir, meaning every phone charge reduces available light time. There is no pass-through charging, so the lamp cannot illuminate while replenishing its own battery.

Questions about this item

How do I confirm the Y39 is working correctly after charging it?

Press the mode button to cycle through the three COB settings — low, mid and high — and verify the output reaches the stated 1500 lumens on the highest setting.

What comes in the box with the WARSUN Y39 and what must I provide?

The light includes a built‑in 3000mAh battery and a Micro USB charging port; you only need to supply a standard Micro USB cable and a 5V USB power source.

Which version of the Y39 should I choose for maximum brightness?

The single model listed delivers 40W and 1500 lumens with three COB modes, so there is no separate version to select for higher output.
