The short version of this Echo Go Plus review: the Echo Go+, as Echo writes it, is the middle rung of Echo Water’s range, a 10 oz bottle with an electrolysis generator in the base that runs a five or ten minute cycle. Echo Technologies claims up to 4.5 ppm of dissolved hydrogen on the long cycle. What makes it unusual is that an outside lab checked. H2 Analytics put a Go+ on a gas chromatograph and measured 4.55 ppm, and a second unit returned after roughly a year of use still measured 4.59 ppm. In a category where tested output normally lands under the marketing number, that is worth knowing.
Two things to be clear about before you read on. This review is built from Echo’s published specifications, manual and warranty, from two laboratory reports commissioned by Echo and published on its own support site, and from what owners report across retailers. We do not own this bottle and we have not run our own tests on it. And the bottle is not glass, whatever else you may have read about it.

What is the Echo Go Plus Hydrogen Water Bottle?
The Echo Go Plus is a high-tech hydrogen water bottle that dissolves molecular hydrogen into drinking water using electrolysis, rather than filtering or flavouring it. The water itself stays water; what changes is the amount of dissolved hydrogen gas in it. If the category is new to you, our hydrogen water bottle explained guide covers how SPE and PEM electrolysis works before you start comparing individual models.
Product Overview
The Go+ is a 10 oz bottle with the generator built into the base. Echo quotes 9.5 oz of usable fill, which is the number that actually matters, and it is about a large mug. Most people run it two or three times a day rather than once. One button drives it: press once for a five minute cycle, twice for ten, and a small display counts the cycle down and shows the battery level.
What separates it from the cheaper Echo Go is output and convenience. Echo’s own comparison puts the Go at 1.2 to 1.8 ppm and the Go+ at 2.5 to 4.5 ppm, and unlike the Go, the Go+ will run a cycle while it is plugged in. Hydrogen bottles run from the cheapest models around $50 to around $500, and the Go+ sits firmly at the premium end of that spread, in the $200 to $300 bracket. For where it lands against everything else, we keep a wider list of hydrogen water bottle picks.
What the Lab Measurements Actually Show
Most hydrogen bottles are sold on a number printed on the box. This one has been measured by a third-party laboratory, twice, and Echo publishes both reports on its support site. That is the single most useful fact about the Go+, so it is worth being precise about it.
| Source | Unit tested | Short cycle | 10 minute cycle |
|---|---|---|---|
| H2 Analytics, report H2A-240603-2 (3 June 2024) | new unit | 2.57 ppm (3 minute cycle) | 4.55 ppm |
| H2 Analytics, report H2AR-241125-1 (25 November 2024) | returned after about a year of use | 2.80 ppm (5 minute cycle) | 4.59 ppm |
| Echo’s own published claim | — | up to 2.5 ppm | up to 4.5 ppm |
Both reports used an SRI 8610C gas chromatograph with static headspace analysis, three runs per cycle, with the results adjusted to standard conditions. The measured figures meet or slightly exceed Echo’s own claim, which is not what usually happens when bottles in this category get tested.
Two honest caveats. First, both reports were commissioned by Echo and are hosted by Echo, so they are third-party testing rather than independent testing, and you should read them in that light. Second, the 2024 report tested a three minute short cycle while the current product uses five minutes, so those two short-cycle numbers are not directly comparable and we have not blended them.
A separate SGS Silver State Analytical Laboratories panel on water from a Go+ found no detectable platinum or titanium, and lead, arsenic, copper, cadmium, chromium, nickel and zinc all below reporting limits. That matters more than it sounds: the electrodes are platinum-coated titanium, and the obvious question about any electrolysis device is whether the electrode material ends up in the water.
Key Features of the Echo Go Plus Hydrogen Water Bottle
The specifications below come from Echo’s own manual and spec sheet. Where Echo’s documents disagree with each other, we say so rather than picking the reading we prefer.
Hydrogen Infusion Technology
The Go+ uses solid polymer electrolysis with a dual-chamber proton exchange membrane and a dedicated oxygen vent. In plain terms, an electric current splits some of the water, the hydrogen dissolves into what you drink, and the oxygen and any ozone are vented out of a port instead of staying in the bottle. Echo states that the platinum-coated titanium electrodes never touch the drinking water, and that the process leaves pH essentially unchanged.
That last point is worth separating out, because the two get confused constantly: hydrogen water is not alkaline water. Alkaline water is about pH. Hydrogen water is about dissolved hydrogen gas. The Go+ is doing the second thing, not the first.
The unit also runs a self-cleaning routine that periodically reverses electrode polarity to shed mineral build-up, which is why Echo says the Go+ does not need the regular cleaning cycle the older Echo Go does.
Design & Build Quality
The body is plastic, not glass, and Echo’s own paperwork is untidy about which plastic. Its comparison page calls the Go+ food-grade, BPA-free polycarbonate and explicitly contrasts that with the Tritan used in the cheaper Echo Go. Its spec sheet for the same product says Tritan. Amazon’s listing says polycarbonate. What every source agrees on is that it is a BPA-free plastic, and that is the point: it keeps a bottle with a battery in its base light enough to carry and hard to shatter. Until Echo reconciles its own documents, we are not going to guess which plastic it is.
Echo does not publish official height, width or weight figures for the Go+, and the dimensions quoted on retail listings, including the spec list on the card above, are not consistent with one another. Treat any of them as approximate.
Battery Life and Charging
The battery is a 2200 mAh lithium-ion cell, 3.7 V, rated at 8.14 Wh, and Echo rates it at five to ten cycles per full charge rather than a number of days. It charges over USB-C from the supplied 5 V / 2 A block, and Echo is blunt about the rules: use that block rather than a fast charger, and do not leave it charging beyond four hours. That four hour figure is a safety ceiling, not a target. Unlike the cheaper Echo Go, the Go+ will run a cycle while it is plugged in.
Ease of Use and Maintenance
This is where most Go+ owners go wrong, so it is worth stating plainly. The Go+ is not designed to run on tap water. Echo specifies reverse osmosis, distilled, spring or filtered water, and says chlorine and chlorides damage the membrane. If you filter your own water, Echo asks that the filter remove at least 99% of chlorine. Highly mineralised water is discouraged too.
- Fill only to the fill line, and never run the generator dry.
- Hand wash the bottle and cap with warm water and a non-abrasive detergent. Never put it in a dishwasher, and keep water out of the pressure-release valve in the centre of the cap. Water damage voids the warranty.
- Descale one to two times a month with white vinegar, lemon juice or citric acid. Echo specifically says not to use apple cider vinegar.
- After use, leave about a tablespoon of water in the generator to keep the membrane wet, pour the rest out, and leave the cap off so condensation can escape. Storing it sealed and full is how it grows mould.
- Echo suggests drinking the water within about two hours, because dissolved hydrogen escapes from an open bottle.
Benefits of Using the Echo Go Plus Hydrogen Water Bottle
Two things decide whether the Go+ earns its price: how much hydrogen it actually puts into the water, and how much friction it adds to your day. The first has an answer. The second depends on you.
Hydration and Health Benefits
Molecular hydrogen has been studied as an antioxidant, and most of that work is still early. The trials tend to be small, short, and varied in what they measure. That is enough to make the idea interesting and not enough to promise anyone a result.
Echo’s own manual is stricter on this than most of the pages reviewing its products: the Go+ has not been evaluated to diagnose, treat, cure, or prevent disease. Echo’s materials reference a therapeutic threshold from around 0.5 ppm, and a ten minute cycle measured 4.55 ppm in the lab, so the dose is comfortably above the level the research tends to use. Whether that dose does anything for you is a different question from whether the bottle delivers it, and only the second one currently has a reliable answer.
This is general information, not medical advice. If you have a health condition or take medication, talk to a healthcare professional before changing what you drink.
Portability and Convenience
It is a 10 oz bottle, so it fits a bag or a cup holder easily, and the battery means you are not tied to a socket. The practical detail nobody mentions is air travel: the 2200 mAh lithium-ion cell sits inside airline limits, which makes the Go+ carry-on only, never checked luggage. Empty it before security and refill after. Echo notes that cabin pressure can slightly reduce output in flight.
How It Works
Press the button once and the Go+ runs a five minute cycle; press twice for ten minutes. Current passes through the water, the membrane separates the gases, hydrogen dissolves into the water and oxygen leaves through the vent. Echo puts the five minute cycle at up to 2.5 ppm and the ten minute cycle at up to 4.5 ppm; the lab figures above are what those cycles actually produced under test.
Where the Echo Go Plus Falls Short
No review is worth much if everything in it is positive. These are the things that would make us hesitate.
- 9.5 oz is genuinely small. If you want all your water hydrogenated you will be running cycles all day, or decanting into a bigger bottle. Echo openly suggests the latter.
- Five to ten cycles per charge is not much for heavy use, and the charging rules are strict: the supplied 5 V / 2 A block only, no fast chargers, four hours maximum.
- The battery and the charging cord are excluded from the warranty. On a device this expensive, the part most likely to wear out is the part not covered.
- It will not tolerate chlorinated tap water. If you have no filter, factor in the running cost of bottled or filtered water, because that is now part of owning it.
- Hand wash only, and water damage voids the warranty. Descaling one to two times a month is a real chore, not a formality.
- Owner reports cluster on the same failures. Across Reddit, Trustpilot and retailer reviews the recurring complaints are seal leaks, charging failures, units dying within months, and slow support. Retailer ratings for this model are strongly polarised rather than uniformly good. We cannot put a failure rate on that and will not invent one, but the pattern is consistent enough to mention.
How the Echo Go Plus Compares to the Rest of Echo’s Range
The Go+ is the middle option, and Echo publishes enough to place it precisely.
| Echo Go | Echo Go+ | Echo Flask | |
|---|---|---|---|
| Usable capacity | 9 oz | 9.5 oz | 12 oz |
| Hydrogen | 1.2 to 1.8 ppm (3 or 10 min) | up to 2.5 / 4.5 ppm (5 or 10 min) | up to 5 ppm (10 min), up to 8 ppm (20 min) |
| Body | Tritan BPA-free plastic | BPA-free plastic; Echo’s docs say polycarbonate in one place and Tritan in another | — |
| Routine cleaning cycle | every few days | not needed, self-cleaning | — |
| Use while charging | no | yes | — |
| Extras | — | digital display | LCD touchscreen, Bluetooth, health-app sync |
The honest headline: the Go+ is a clear step up from the Echo Go, and it is beaten on raw output by Echo’s own Flask. If concentration is the only thing you care about, the Flask wins on Echo’s own numbers. We set the two Go models against each other in the echo go vs echo go+ comparison, and if you are weighing the Flask specifically, start with echo go+ vs echo flask.
Outside Echo’s own range, how piurify vs echo go+ stack up is the closest like-for-like on price, and how echo go bottle vs ionbottles stack up covers the cheaper end of the same category. For the glass-bodied alternatives people routinely confuse with this one, see the echo flask vs echo go comparison and Echo Flask vs Evolv.
Who Should Buy the Echo Go Plus Hydrogen Water Bottle?
Short answer: buy the Go+ if you want a measured hydrogen dose you can carry, and you are content to run it two or three times a day on filtered water.
Target Audience
It suits people who already drink enough water and want to add something to it, rather than people hoping a gadget will make them drink more. Athletes and gym users are the most obvious fit, because recovery is the part of the hydrogen literature with the most behind it. Frequent travellers are the other, because it is carry-on legal and does not need a socket to work.
Specific Situations Where the Echo Go Plus is Especially Useful
Buy the cheaper Echo Go instead if you mainly want to find out whether hydrogen water does anything for you, since it costs less and still measures 1.2 to 1.8 ppm. Buy the Flask if output is the point. And skip all three if your tap water is chlorinated and you have no filter, because the membrane will not tolerate it and you will end up buying water to put in your water bottle.
Warranty, Returns and Buying a Genuine Unit
Echo Technologies covers the Go+ with a five year limited warranty against factory defects and material flaws. The exclusions are the interesting part: the battery, the charging cord and the charging block are not covered, nor are non-performance parts such as the speaker or LED lighting. The warranty is for the original owner only, is not transferable, and ends if the device is resold. Claims require proof of purchase and, in practice, a short video showing the serial number and the fault.
It also only applies if you bought from Echo or an authorised dealer. Amazon and Walmart both qualify; private marketplace listings do not. Buying direct gives you a 60 day return window, while third-party purchases follow that retailer’s policy.
One reason to care where you buy: in July 2025 Echo issued a public advisory about imitation hydrogen bottles, saying cheap copies often lack proper proton exchange membrane gas separation and can generate chlorine, ozone or hypochlorous acid. That is Echo’s own claim about its competitors and should be read as such. The checkable part is narrower and still useful: warranty eligibility depends on the channel you bought through, so buy somewhere Echo recognises.
The Verdict on the Echo Go Plus
The Go+ does the one thing it is sold to do, and there is outside evidence that it keeps doing it: 4.55 ppm new, 4.59 ppm on a unit a year old. That is rarer in this category than it should be, and it is why this Echo Go Plus review lands positive despite everything in the section above.
What you are paying for is the measurement, not the bottle. At the $200 to $300 end of the market you are buying 9.5 oz at a time, a battery excluded from its own five year warranty, and a device that will not tolerate tap water. If those three sit badly with you, the Go+ is the wrong buy and no amount of dissolved hydrogen fixes that. If they do not, it is a straightforward recommendation, and the lab numbers are the reason.
Frequently Asked Questions
How long does the Echo Go Plus last?
Echo Technologies covers the Echo Go Plus with a five year limited warranty against factory defects and material flaws, which is the only durability figure with a source behind it. Note what the warranty excludes: the battery, the charging cord and the charging block are not covered, and water damage voids it. Hand washing only, descaling once or twice a month, and using filtered rather than tap water are the three things most likely to extend its working life.
Is a hydrogen water bottle HSA eligible?
Hydrogen water bottles like the Echo Go Plus are usually treated as general wellness products rather than medical devices. HSA eligibility depends on your provider and on whether a clinician has recommended it for a specific condition, so check with your HSA administrator before assuming it qualifies.
Can I use tap water in the Echo Go Plus?
No. Echo specifies reverse osmosis, distilled, spring or filtered water, and says chlorine and chlorides damage the membrane that makes the hydrogen. If you filter your own water, Echo asks that the filter remove at least 99% of chlorine. Highly mineralised water is discouraged as well, because it accelerates scale build-up on the electrode plates.
Is there a downside to drinking hydrogen water?
The main downsides are practical rather than medical. Research on molecular hydrogen is still early and mostly small-scale, so nobody can promise you a result, and Echo’s own manual states the product has not been evaluated to diagnose, treat, cure, or prevent disease. On the device side you are committing to filtered water, hand washing, regular descaling and a battery that is not covered by the warranty. If you have a health condition or take medication, talk to a healthcare professional first.
How long does hydrogen water stay hydrogen-rich after a cycle?
Not long. Dissolved hydrogen escapes from an open container, which is why Echo recommends drinking the water within about two hours of the cycle finishing and keeping the cap on until you do. This is also why bottle format devices exist at all: they make the water where you are going to drink it, rather than storing it.
Can I take the Echo Go Plus on a plane?
Yes, in your carry-on. The 2200 mAh lithium-ion battery sits within airline limits for cabin baggage, but lithium batteries are not permitted in checked luggage, so it must travel with you. Empty the bottle before security and refill it afterwards. Echo notes that cabin pressure can slightly reduce hydrogen output in flight.
