# Pocket-Size Energy Concentrates IronMaxx Packs Squee'Nergy into a 65ml Bottle By Amy Duong | Written with AI assistance | Published 2026-10-13 | Beverages, Spirits & Alcohol Source: Trend Hunter, https://www.trendhunter.com/trends/pocket-size-energy-concentrates References: [stack3d](https://www.stack3d.com/2026/10/ironmaxx-squee-nergy)  IronMaxx is extending its SqueeZero format into energy with Squee'Nergy, a liquid concentrate that mixes plain water into an energy drink. It suits people who want a caffeinated beverage without carrying a larger drink, and each serving blends 100mg of caffeine into 500ml of water. One 65ml bottle makes just over eight liters, giving the pocket-size format far more mileage than its size suggests. Classic Energy is the only flavor, sweetened with sucralose and stevia and kept [free of sugar and calories](https://www.trendhunter.com/trends/citrus-freeze). That keeps the format close to a familiar energy taste while avoiding extra calories in the bottle you carry. At €4.90, Squee'Nergy turns energy into a refill-style purchase instead of a one-and-done buy. The 65ml bottle also pushes IronMaxx's concentrate model beyond flavoring, giving repeat users a compact way to keep caffeine on hand.
