Echo Go vs Echo Go+: the short answer

Of the two, the Echo Go+ is the better bottle. Echo Water rates it at up to 4.5 ppm of dissolved hydrogen against the Echo Go’s up to 1.8 ppm, it has an OLED display, and you can run it while it charges. The Echo Go is the simpler, cheaper one. Before you buy either, though, two things: Echo Water has stopped selling both of them, and the cheap listings on Amazon branded “Echo Go” are a different bottle from a different seller.

If you want the wider field rather than these two, start with our roundup of which is the best hydrogen water bottle.

Last checked: 12 September 2026. Specifications, warranty terms and availability were verified against Echo Water’s own user manuals, specification sheets and warranty guide, and against the live Amazon listings, on that date.

Two different bottles are sold as “Echo Go”

This is the part that trips people up, and it is worth two minutes before you spend anything. Searching for an Echo Go returns two quite different products.

• Echo Water’s Echo Go. A 9 oz bottle made from BPA-free Tritan. Echo Water’s user manual rates it at up to 1.2 ppm on the 3-minute cycle and up to 1.8 ppm on the 10-minute cycle. This is the product the rest of this comparison is about, and it is the one in the echo go verdict.
• A 380 ml glass bottle whose Amazon brand field also reads Echo Go. It is sold by a third-party seller, it is made of borosilicate glass rather than Tritan, it holds 380 ml rather than 9 oz, and it sits under $100 rather than in the same bracket. The seller quotes the same 1.2 ppm and 1.8 ppm cycle figures.

We are not making any claim about a relationship between the two companies in either direction, because there is nothing public to base one on. The practical point is only that they are not the same bottle. Three things on the listing tell them apart: the Sold by line, the material (glass against Tritan) and the capacity (380 ml against 9 oz). If any of those says glass or 380 ml, you are not looking at Echo Water’s Echo Go, and Echo Water’s warranty does not apply to it. There is more on the wider category in our full hydrogen water bottle guide.

Where to buy each one

The table below is our affiliate module. The left column is the third-party glass bottle described above, not Echo Water’s Echo Go, which Echo Water no longer sells. Check the listing details before ordering.

What the hydrogen numbers actually mean

Hydrogen output: 1.8 ppm against 4.5 ppm

Both bottles work the same way. They use solid polymer electrolysis (SPE) across a proton exchange membrane (PEM). A current runs through platinum-coated titanium electrodes, the membrane keeps the two gases apart so only dissolved hydrogen ends up in the water, and the oxygen leaves through an oxygen vent. Echo Water says the electrodes never touch the drinking water.

The ratings are per cycle rather than a range you land somewhere inside. Echo Water quotes up to 1.2 ppm for the Echo Go’s 3-minute cycle and up to 1.8 ppm for its 10-minute cycle; for the Go+ it quotes up to 2.5 ppm at 5 minutes and up to 4.5 ppm at 10. A short cycle on the Go+ and a long cycle on the Go land closer together than the headline numbers suggest.

Those figures need a frame of reference, and the page you are reading used to print a number without one. Hydrogen’s saturation point in water at ordinary pressure and room temperature is about 1.6 mg/L, which is 1.6 ppm, or 1,600 ppb. A sealed bottle gets past that ceiling because pressure builds inside it, which is why the Go+ has a pressure-release valve and why Echo Water says it can take a week of regular use before the bottle builds full pressure. Open the cap and the level starts falling back toward saturation. Most published hydrogen-water research has worked between 0.5 and 1.6 ppm, and Echo Water puts the therapeutic threshold at around 0.5 ppm, so on its own numbers even the Echo Go’s short cycle clears the range the studies used.

How much water each one holds

This is the one spec nobody agrees on. Echo Water’s support comparison says 9 oz for the Echo Go and 9.5 oz for the Go+. Echo Water’s own Amazon listing and its Go+ specification sheet both say 10 oz for the Go+. A major retailer’s chart says 9.5 oz and 10 oz. Whichever set is right, the gap between the two bottles is under an ounce, and both are small enough that a cycle is a glass of water rather than a day’s supply. If capacity is what you care about, neither of these is the answer.

Cycle times and how long you wait

The Echo Go runs a 3-minute or a 10-minute cycle; press once for the short one, twice for the long one. The Go+ runs 5 or 10 minutes on the same one-press, two-press pattern. So the Echo Go is actually the quicker of the two if you are in a hurry, and the Go+ is the one that rewards waiting. Echo Water says to drink the water within two hours either way.

What the bottles are made of

The Echo Go is BPA-free Tritan. The Go+ is where Echo Water contradicts itself: its Go+ specification sheet lists the bottle material as BPA-free Tritan, while its own comparison article and its Amazon listing both describe food-grade polycarbonate. We have not handled either bottle, so we are not going to resolve that for you by picking one; if the material matters to you, ask Echo Water directly before ordering. Both descriptions agree the plastic is BPA-free, and both bottles use platinum-coated titanium electrodes.

Living with them

Both bottles need the same two routines: a cleaning cycle and periodic descaling. How often depends almost entirely on the water you put in them.

Cleaning and descaling

It is worth correcting something this page previously got wrong: both bottles have a self-cleaning function. The Echo Go’s user manual describes running it once a week by holding the button for three seconds, which reverses the electrodes and generates oxygen. The Go+ does the same thing automatically through polarity reversal. The manual adds a warning worth repeating: do not drink the water after a cleaning cycle.

For descaling, Echo Water’s comparison article says both bottles need it one to two times a month. Its Go+ manual describes filling the generator about an eighth full with white vinegar, leaving it at least two hours, then rinsing and running a cycle. Lemon juice or citric acid work as alternatives; it says to avoid apple cider vinegar. Nothing goes in the dishwasher, and nothing gets submerged, because water damage voids the warranty.

What water to use

Echo Water is specific about this and the guidance is the same for both bottles. Use RO water, distilled water, spring water or filtered water. Avoid tap water, chlorinated water and highly mineralised water. Chlorine damages the generator membrane, and chloride ions in the source water are what produce the occasional chlorine smell people report. High TDS water is also what drives descaling frequency up. If you are filtering your own, Echo Water asks for a filter that removes at least 99 percent of chlorine.

Battery, charging and flying with them

The Go+ carries a 2,200 mAh, 3.7 V, 8.14 Wh lithium-ion cell and charges over USB-C from a 5V/2A block. Echo Water says not to use a fast charger, not to charge for more than four hours, and that the battery and the charging cable sit outside the warranty. It rates the Go+ at 5 to 10 cycles per charge. It does not publish an equivalent figure for the Echo Go, whose manual asks for the same 5V/2A block and a two to three hour charge.

Both are carry-on only for air travel. That is the normal rule for a lithium battery rather than anything specific to these bottles, and Echo Water lists it on the Go+ specification sheet. It is worth knowing before a flight rather than at the bag drop.

What each one costs

We do not print live prices, because they move and an out-of-date figure is worse than none. In bands: the Echo Go+ sits in the upper $200s on Amazon. The third-party glass bottle in the module above sits under $100. Echo Water’s own Echo Go is not on sale from Echo Water at any price, which is covered below.

So the honest framing is not a fixed gap but a ratio: the Go+ costs roughly three times what the glass bottle does. For that you get about double the rated hydrogen, an OLED display and the ability to run it while it charges. Whether that is worth it depends on whether you would actually use the longer cycle, given that a 10-minute run on the cheaper bottle already clears the concentration most of the research used. If you are shopping by budget rather than by brand, we have separate roundups of portable hydrogen water bottles under $100 and budget-friendly hydrogen water bottles under $50.

What the 5-year warranty actually covers

Both bottles are covered by a five-year warranty from Echo Technologies LLC, and it is narrower than the headline suggests. Reading Echo Water’s own Echo Go+ warranty guide: it covers the original purchaser only and is non-transferable, so cover ends if the bottle is resold or passed on. The battery is not covered. The lid, seal, charging cord and power block are covered for 30 days from delivery and no longer. Parts that do not affect hydrogen production, such as the speaker and the LEDs, are excluded outright. Physical damage and water damage are excluded, and the bottle is not dishwasher safe.

One thing that does work in a buyer’s favour: the guide lists Amazon among its authorized retailers, alongside Walmart and wholesale distributors, so buying the Go+ there keeps you eligible. You need to keep the receipt, because Echo Water asks for proof of purchase showing date, place and price on any third-party sale. Private marketplaces such as eBay are not eligible at all. And none of this attaches to the third-party glass bottle, which is not an Echo Water product and carries whatever its own seller offers.

Can you still buy them in 2026?

This is the part that changes the answer, and no other comparison of these two bottles seems to mention it. Echo Water has discontinued both. Its shop lists neither: the Echo Go product page now redirects to the Echo Water homepage, and the Echo Go+ product page redirects to the Echo Flask, which is the company’s current portable bottle. That redirect is Echo Water’s own signpost about what replaced the Go+, not our inference.

In practice that means the Go+ is still findable through Amazon’s Echo Water Store listing and is still warranty-eligible if you keep the receipt, while Echo Water’s Echo Go is not available new from the manufacturer at all. If you want something the maker is still standing behind and still shipping, the Flask is the one to look at, and we cover it in the echo flask verdict.

Who should buy which, and who should buy neither

Buy the Go+ if you want the higher hydrogen rating, you will use it most days, and being able to top it up while it charges matters to you. It is the one Echo Water kept selling longest, it is still on Amazon, and the warranty still applies there. Our full write-up is the echo go plus verdict.

Buy neither, for now, if what you actually want is a current bottle with a warranty you can claim and a maker who will still be supporting it in two years. Echo Water has moved on to the Flask, and the Echo Go has gone from its store entirely. That is not a criticism of the hardware, which by all accounts works; it is just the position the line is in.

The cheap glass bottle is an alternative, not the same thing. At under $100 it quotes the same 1.2 ppm and 1.8 ppm cycle figures as Echo Water’s Echo Go, in a 380 ml borosilicate glass body. If those numbers are what you are buying, it is worth a look for roughly a third of the money. If the Echo brand and a warranty you can claim are what you are buying, it is not a substitute.

What owners report

We have not tested either bottle, so what follows is drawn from owner reviews and public forum threads rather than from our own use, and it should be weighed accordingly. The Go+ sits a little under four stars out of five on Amazon across several hundred ratings, which is a solid but not a glowing score. The complaints that come up repeatedly are slow customer support and slow shipping, and difficulty cleaning around the membrane and the logo recess.

Two of the failure modes owners describe are ones Echo Water documents itself. Filling past the shoulder of the bottle can cause leaks during a cycle, and so can failing to release the pressure once a cycle finishes. Both are avoidable once you know about them, which is an argument for reading the manual rather than an argument against the bottle.
