    Are you feeling the need for power? We've reviewed external battery packs from Limefuel before, but now they've gone crazy big with the new Blast L240X Pro (US$149.99)

    Specifications

    • 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

    Design

    Limefuel makes one of the better-looking external battery packs on the market, with rounded sides that are easy to grip and either a rubberized black or white gloss exterior. There's a single button near the "front" of the Blast L240X Pro that is used for all of the functions - turning on the battery pack, checking the level of charge, and activating the built-in LED flashlight.

    On "top" of the device near that button is a string of green LEDs to tell you the battery level, and on the front face is a single micro-USB input for charging and four USB output ports.

    That means if you have four devices that need charging at once and you're nowhere close to a plug, you're in luck as long as the maximum total current draw isn't more than 4.2 Amps for all four ports or more than 2.4 Amps for any one port.

    How much life will the Blast L240X bring your favorite electronic devices? Well, it depends on the model, but Limefuel estimates up to 158 additional hours of internet surfing, 206 hours of talking on your phone, or up to 552 more hours of listening to music - that last number is a whopping 23 days!

    Functionality

    The unique flat cable included with the Blast L240X can be used for both charging the battery pack and for charging one of your devices. Plug it into your favorite USB charging brick (not included) on one end and into the micro-USB port on the other, and you're set. You might want to consider one of Limefuel's Dual Port Wall Chargers ($16.99) to load up the battery pack, as they're capable of putting out 24 Watts of power at 4.8 Amps.

    The huge capacity of the Blast L240X means that if you've drained the battery, it's going to take almost a day to recharge fully. If you have extreme power needs every day, you might want to get two of these devices and trade them out every other day.

    One of the best features of the Limefuel battery packs is the design. They feel very solid, and you don't have the feeling that the Blast L240X is going to fall apart or break. This thing is built like a tank.

    Unlike most other external battery packs, the Blast L240X provides pass-through charging so that you can charge devices while you're charging the battery pack.

    Conclusion

    The Limefuel Blast L240X offers unmatched capacity and four USB ports, although at the cost of some extra weight. At $150, it's also one of the most expensive external battery packs we've tested. But if you need lots of power while traveling, the Blast L240X is your best companion.
