The Sigelei Laisimo F4 features a massive 360 watts of power, two or four batteries, a power bank function, a 1.3 inch color screen, temperature control with TCR and a customizable LED light.  The device is available in black, red, silver and blue.


For a mod that uses up to four batteries, the size is still decent at 83.5mm x 43mm x 51.5mm. The unit’s appearance is bulky, but very modern with curved corners and ventilation holes that perfectly integrate into the design.  A Laisimo logo on the side lights up thanks to a customizable LED that can be set to purple, green, yellow and more.  Further enhancing the look of the Laisimo F4 is a large 1.3 inch color screen on the control face with vape data that includes indicators for current mode, current battery level, wattage/temperature, resistance, voltage and number of puffs so far. At the top, there’s a 510 connector for compatibility with most standard builds or tanks.


Powered by either four or two 18650 batteries, the F4 can charge other USB capable devices — smart phones and tablets for example —  in power bank mode. The four cells are bottom loaded by opening a convenient hinged cover that slides open and utilizes powerful magnets to ensure it stays in place.  An onboard charging system that connects to any wall outlet/computer via the micro USB port permits charging the cells without removing them from the mod.  When connecting the mod to a computer, you may update the operating system by downloading the latest firmware from the Laisimo website.  In this way, you will ensure compatibility with newer atomizers in the marketplace.

The Sigelei Laisimo F4 is built with a whopping 360 watts of power, but if you use only two batteries, the output is limited to 220 watts.  There’s also a temperature control output system that allows for a higher output — 662 degrees Fahrenheit — compared to other high wattage devices.  Variable temperature mode works with all the standard atomizer heating elements — nickel, titanium, stainless steel — and there are two memory slots in which you may set TCR values.  With a low resistance capability of 0.05ohm, this mod is sure to work with any build or tank in your collection.  Safety was also of concern when designing this mod, so Sigelei designed the Laisimo F4 Mod with low/high battery warning, overheating protection, short circuit protection, overtime protection, puff monitoring and intelligent atomizer detection.

Batteries (4 x 18650) &/Or External Charger




We do not recommend using the built-in USB charging feature on mods that use replaceable lithium ion cells. Lithium ion batteries must be balance charged using a proper external charger to avoid damaging the cells and to reduce the risk of venting. Micro and mini USB ports are notoriously fragile and as such we do not offer a warranty on any USB charging ports if you choose to ignore this warning.

    Brilliant mod, perfect size for my Aromamizer Titan tank. Hits hard for a regulated mod. Easy menu system, flash pretty lights ( turned mine off to save power) colour screen. Battery life is awesome even with my Titan running at 127 watts ( yes I’ve got big insane coils mounted) and I still get 2 days out of the mod, more if I use it occasionally. Fast shipping from these guys as well. Excellent place to shop.
