Prodigy X Hydrogen Water Bottle vs iBottle+: Is the Upgrade Worth It?

“iBottle+ is our pick for buyers who want more capacity and a choice of bottle sizes, with the 400 mL model holding 190 mL more than Prodigy X.” Sam, iBottle

iBottle+ is our pick for buyers who want more capacity and a choice of bottle sizes. At A$199, you can choose 230 mL or 400 mL, with gift packaging and free Australian shipping included. The iBottle+ hydrogen water bottle also has a published report for a tested 400 mL unit, giving you specific results to read before buying. Prodigy X costs A$119.90 and holds 210 mL. That makes the iBottle+ upgrade A$79.10. Whether the extra spend suits you comes down to how much water you want per fill, which package you prefer and how you plan to use the bottle.

Prodigy X vs iBottle+: the buying comparison

Prices are the listed offers checked on 24 September 2026. Both bottles qualify for their sellers’ stated free Australian delivery at these prices, so the A$79.10 difference is the bottle price difference.

What does the extra A$79.10 buy?

The clearest reason to choose iBottle+ is the 400 mL option. It holds 190 mL more than Prodigy X’s 210 mL bottle. That is useful if you prefer a larger drink at your desk, carry your bottle between appointments or simply want more water available before refilling. If a smaller bottle suits your bag better, the 230 mL iBottle+ offers a compact alternative at the same A$199 price. Its capacity is only 20 mL above Prodigy X, so the larger capacity benefit is mainly a reason to choose the 400 mL model. Our iBottle model and size comparison can help you choose between the options. The package also makes iBottle+ a straightforward gift choice. Gift packaging, the charging cable and the manual come with the bottle. You can choose the size to suit the recipient without paying more for the 400 mL option.

How should you compare the hydrogen testing?

Prodigy X publishes a third-party testing panel naming H2 Analytics and provides a QR code labelled Full Report. Its product listing offers five and ten minute cycles. The published iBottle+ report records a mean of 4,050 ppb after one five minute cycle and 6,200 ppb after two consecutive five minute cycles. Those results apply to the tested 400 mL unit using distilled water at 20°C and H2Blue reagent titration. Read each result alongside its cycle length and test conditions. Our recommendation here rests on the iBottle+ 400 mL’s roomier capacity and complete package.

A practical option for the 400 mL model

For the iBottle+ 400 mL, an A$69 replacement glass kit is available with glass, lid, charging cable and manual. It fits the iBottle+ 400 mL and original iBottle 400 mL.

Our choice: iBottle+ for the roomier bottle

We recommend iBottle+ 400 mL if your budget allows A$199 and you want more water per fill, an included gift package and a published report covering that model. For buyers weighing the upgrade, the extra 190 mL of capacity is the strongest everyday reason to choose iBottle+. Choose your iBottle+ size here.
