Frequently Asked Questions
Q: What USB sources can I use to recharge the ESMARTER COB LED work light?
A: The built-in 18650 battery charges via any standard USB port — including a laptop, power bank, AC wall adapter, or car charger. Four USB cables are included in the box for added convenience. A full charge takes approximately 3 hours from zero.
Q: How long does the battery last on a single charge?
A: On High COB LED mode, expect 3–6 hours of runtime. Switching to Low COB LED mode extends battery life significantly — up to 10–16 hours — making it ideal for all-night camping or extended work sessions.
Q: Will the magnetic base hold the light securely while I work?

Q: Is this work light waterproof?
A: The ESMARTER W51 is water-resistant, meaning it performs reliably in rain or light snow conditions. However, it is not designed for submersion — do not place it directly in water.
Q: What is the difference between the Big and Small models?
A: Both models share the same 5 lighting modes and features. The Big model measures 14.8 × 4.7 cm, while the Small model measures 11 × 3.6 cm — ideal if you need an even more pocket-friendly option for everyday carry.
