“iBottle+ 400 mL is our pick for a glass bottle, a larger serving and a lower purchase price.”
Sam, iBottle
iBottle+ is our pick over the AlkaWay 350 mL Hydrogen Water Bottle for buyers who want a glass bottle, a larger serving and a lower purchase price. The 400 mL iBottle+ costs A$199 with free Australian shipping. That is A$30 less than AlkaWay’s A$229 product price, with 50 mL more capacity. A compact 230 mL iBottle+ is also available at the same price.
This comparison covers AlkaWay’s named 350 mL Hydrogen Water Bottle. Its separate 200 mL Portable Hydrogen Water Bottle is a different product. Prices and product details were checked on 25 September 2026.
iBottle+ 400 mL brings a glass vessel to this buying comparison.
AlkaWay vs iBottle+: quick comparison
| Buying detail | AlkaWay Hydrogen Water Bottle | iBottle+ |
|---|---|---|
| Current product price | A$229 | A$199 |
| Capacity | 350 mL | 230 mL or 400 mL |
| Bottle body | Food-grade Tritan plastic | Glass vessel on the 400 mL option |
| Hydrogen generation | Rechargeable SPE/PEM bottle | Rechargeable SPE/PEM bottle |
Both are reusable hydrogen water generators. The useful buying differences here are the price, the drinking vessel you prefer and how much water you want each time you fill it.
Which size and material suit you?
The 400 mL iBottle+ is the choice we would make for a desk, bedside table or regular use at home. It gives you a little more water than the AlkaWay 350 mL without moving to a large countertop unit. If drinking from glass is part of what you enjoy about a bottle, this is the clearest reason to choose it.
Prefer a smaller serving and a compact design? Choose iBottle+ 230 mL. You can pick the size that fits your routine without paying extra for the larger option. Our iBottle model and size guide shows the choices together.
What will you pay in Australia?
At the checked prices, the product-price difference is A$30 in favour of iBottle+. Its free Australian shipping also makes the delivered price straightforward.
AlkaWay advertises free Australian shipping on orders over A$300. A single A$229 bottle is below that threshold, so check the delivery quote for your address. The A$30 comparison above is the difference between listed product prices, before any AlkaWay shipping charge.
What testing information is available?
AlkaWay publishes an H2 Analytics testing summary for its 350 mL bottle. Both products provide testing information to help you assess the purchase.
The published iBottle+ report records a mean of 4,050 ppb after one five-minute cycle and 6,200 ppb after two consecutive cycles. Those results concern the tested 400 mL unit using distilled water at 20°C and H₂Blue reagent titration.
Reports use different methods, so each result needs to be read within its own test conditions. Our recommendation here rests on the purchase price, glass option and size choice.
What comes with iBottle+?
Your iBottle+ includes a charging cable, manual and gift packaging. It is a complete bottle purchase, with the essentials included for getting started.
For the 400 mL version, a matching A$69 replacement glass kit is available separately. It includes the glass vessel, lid, USB cable and manual, allowing you to retain a working generator base when replacing the glass. This kit fits the 400 mL models only.
Our pick: iBottle+ 400 mL
For an Australian buyer deciding between these two bottles, iBottle+ 400 mL brings together the stronger value proposition: a lower product price, free Australian shipping, a glass drinking vessel and more water per fill. Choose the 230 mL version if compactness matters more to you.
