Limefuel Blast L240X Pro Review: Abundant Battery Power

Are you in dire need of a reliable power source? We’ve previously explored various external battery packs from Limefuel, but their latest release, the Blast L240X Pro priced at US$149.99, takes things to a whole new level.

  • Dimensions: 6.1 x 3.1 x 0.9 inches (155 x 79 x 24 mm)

  • Weight: 17.8 ounces (505 grams)

  • Capacity: 24000 mAh / 91.2 WH

  • Charging time: 16-24 hours

  • Total output: 5V/4.2A (Max)

  • Connector: USB to micro-USB/Lightning connector


The aesthetics of Limefuel’s external battery packs are quite appealing, featuring smooth, rounded edges that fit comfortably in your hand, and are available in either a rubberized black or a sleek white gloss finish. The Blast L240X Pro includes a central button that manages all operations including power, battery status check, and an integrated LED flashlight.

Located at the top near this button are several green LEDs that display the current battery level, while the front panel houses a micro-USB input for charging and four USB output ports.

This setup is ideal for charging multiple devices simultaneously, especially when access to a power outlet is limited, as long as the total current draw does not exceed 4.2 Amps across all ports or 2.4 Amps per port.

The Blast L240X can significantly extend the battery life of your devices, with Limefuel claiming it can provide up to 158 additional hours of web browsing, 206 hours of talk time, or up to 552 hours of music playback, which equates to nearly 23 days of continuous use!


The Blast L240X comes with a unique flat cable that serves dual purposes: charging the battery pack itself and charging your devices.

Connect one end to a USB charger (not included) and the other to the micro-USB port. For optimal charging speeds, you might consider purchasing one of Limefuel’s Dual Port Wall Chargers for $16.99, which can deliver 24 Watts at 4.8 Amps.

Given its substantial capacity, the Blast L240X requires nearly a full day to recharge once depleted.

If your daily power needs are high, consider rotating between two units to ensure continuous availability.

Limefuel’s battery packs are robustly constructed, giving a sense of durability and reliability. Moreover, the Blast L240X supports pass-through charging, allowing you to charge other devices while it is being charged.


Although it’s on the heavier side and one of the pricier models we’ve tested, the Limefuel Blast L240X’s massive capacity and multiple USB ports make it an invaluable travel companion for those in need of extensive power on the go.
