PEAKSPANHow It Compares
Hydrogen water bottles nearly all come out of a small number of factories, so the hardware is frequently similar and any seller telling you otherwise is guessing. What differs enormously is how much of it you are allowed to check. That is the comparison worth making, so it is the one we made, and we have printed the rows we lose in the same size type as the ones we win.
Nine third-party documents, published in full on the certificates page.
What Is Actually Different Here
Not the hardware. Everything around it.
The documents are on the website, not described on it
Nine third-party reports, every page of them, downloadable. Certificate numbers, laboratory names, signatures and dates are visible. In the July 2026 research set, other listings usually described documents without publishing the full files.
The documents name the model you are buying
Seven documents directly name H88, five also name W10-2, and one separate UN 38.3 report names battery pack H88-ZQ-29. A model list does not establish performance or whole-production conformity.
BPA is a laboratory result, not an adjective
Report ZTS26062239DRC records BPA not detected at a 0.05 mg/kg reporting limit in submitted body and lid samples and reports its extractive results. The electrode and membrane assembly was not tested, and the cited regulations do not align cleanly with both declared materials.
The battery has a full transport-test report
The H88-ZQ-29 battery pack has a complete UN 38.3 report - all eight tests, including crush, overcharge and forced discharge - and is rated 9.25 Wh. The report covers the tested battery pack; it is not an airline-acceptance promise.
The headline number is lab-measured, not just claimed
QTT report LH2025110014-1 records 8,600 PPB in the sealed cup immediately after one 10-minute cycle on a submitted H88 sample. Companion report LH2025110015-1 records ozone not detected under its stated method. Both were commissioned by the manufacturer, not Peakspan.
We publish what we do not have
No pitcher hydrogen test, no chlorine test, no electrode migration test, no electrical-safety certificate, no ISO, no patent paperwork. The gaps are on the certificates page in the same size type as everything else, and the words certified, tested, verified and measured never appear next to a figure that has no report behind it.
The comparison includes the rows we lose
Final water guidance and cycles-per-charge figures ship with the production run. Online checkout is now available, and the full technical record stays on the comparison table because a table you win every row of is an advertisement.
What You Can Actually Check Before You Buy
No competitor is named, pictured or linked. The right-hand column describes what we repeatedly found across the category while researching it, not any one company.
| Peakspan H2 | What we found across the category | |
|---|---|---|
| Test documentsPeakspan H2 | Nine third-party documents published in full and downloadable as PDFs, each with a certificate or report number, an issuing laboratory, a signature and a date - including two that measure the water itself: hydrogen concentration and ozone byproduct. | Documents are usually described but not published. Across all 46 product pages of one manufacturer we researched there was not a single downloadable document, and not one document file in a 1,456-item media library. |
| Do the documents name the product?Peakspan H2 | Yes. Seven documents directly name H88, five also name W10-2, and the UN 38.3 report separately names H88-ZQ-29, the bottle's battery pack. | Certificate images frequently name a different model line or a different company from the product they are shown beside. Our own previous supplier's set named a hydrogen-generator range we did not sell. |
| Food-contact testingWorth knowing | Bisphenol A not detected by LC-MS/MS at a 0.05 mg/kg reporting limit, in a laboratory report you can download and read. It covers the bottle body and the lid. It tested two parts, not the electrode and membrane that sit in the water under current - we have asked for that test. And it cites the polycarbonate regulation for a copolyester body, which is the laboratory applying a generic protocol rather than the section that governs the material. |
BPA free is stated on the listing. The underlying report is rarely offered. |
| Battery safetyPeakspan H2 | Full UN 38.3 report, all eight tests passed, on cells new and after 25 charge cycles. The report records 9.25 Wh. It does not establish acceptance by any airline or for any itinerary. | Listings often state battery capacity without publishing the underlying transport-test report. |
| Hydrogen concentrationPeakspan H2 | QTT report LH2025110014-1 records 8,600 PPB in the sealed cup immediately after a 10-minute cycle on one submitted H88 sample. The manufacturer commissioned the test; Peakspan did not. The result is above the manufacturer's 8,000 PPB specification and declines after opening. The result covers one submitted H88 sample under one stated condition, not every production unit, a retained concentration, a dose or a health outcome. It does not cover the W10-2 pitcher. |
A single large number, usually with no cycle time attached, no statement of where or when it was measured, and no published report behind it. |
| Water you can put in itWorth knowing | Not yet published. The QTT test used distilled water, but the production H88 water requirement has not been confirmed in writing. Final usage guidance ships with the production manual. |
A comparable 320 ml bottle we researched accepts TDS 1-800 mg/L, which includes ordinary filtered tap water. |
| Cycles per chargeWorth knowing | Not published. The only H88 estimate is factory-only and conflicts with a comparable unit on a similar-sized cell. A production H88 must be run flat under recorded conditions before a cycle-count claim is made. |
A comparable 280 ml unit on a 2,200 mAh cell is independently rated at 15-20 cycles. |
| Independent price and spec cross-checkThe category | The H88 is sold exclusively through Peakspan, so you will not find this exact unit resold on the major marketplaces. | Widely resold chassis can be compared across several sellers. |
| The gapsPeakspan H2 | Published. We list the documents we do not have - no pitcher hydrogen test, no chlorine test, no electrical-safety certificate, no ISO, no patent paperwork - on the certificates page. | Not something the category tends to do. |
| Who you are buying fromPeakspan H2 | A named UAE seller of record, a Dubai address and published contact details. Online pre-order is open, with the published shipping and 30-day unopened-product return terms. | Frequently a marketplace storefront with no legal entity, no address and no stated warranty holder. |
| Buying it todayThe category | Available for online pre-order through Shopify, with the published return and shipping terms. | Instant checkout, card payment, marketplace buyer protection. |
How this table was built. From independent multi-source research across seven marketplaces and five independent sellers of comparable hardware, consolidated on 27 July 2026, plus the nine third-party documents we hold. Where a comparison goes against us it is printed the same size as the ones that do not, a table you win every row of is an advertisement, and nobody believes one.
Bottle Or Pitcher?
They do the same thing at different scales. The bottle is for one person and travels; the pitcher is for a household and stays on the counter.
| H2 Quantum Flask | H2 Pitcher | |
|---|---|---|
| Capacity | 320 ml | 2,000 ml |
| Made for | One person, on the move | A household, at home |
| Cycle | 5 or 10 minutes | 3 minutes |
| Hydrogen concentration | QTT LH2025110014-1: 8,600 PPB in the sealed cup immediately after one 10-minute cycle on one submitted H88 sample; manufacturer-commissioned | Hydrogen-rich, a gentler everyday concentration; no model-specific hydrogen report exists, so no figure is published |
| Power | 2,500 mAh, 3.7 V, 9.25 Wh battery (UN 38.3 report) | Details announced with the production run |
| Named on the certificates | Yes - model H88 | Yes - model W10-2 |
