DABA Match — Know Before You Buy

Checks if a battery, cartridge, phone case, filter, car part or smart home device fits what you already own, before you buy.

Cordless tool batteries don't fit across brands, and often not within a brand either. Camera lenses don't fit across mounts. Printer cartridges are sold under a different number in different regions for the identical cartridge. PC parts need the right socket, memory and storage standard — or, for a laptop, the right charger or battery for that model. A phone case is cut for one exact model. Fridge filters, coffee pods, vacuum bags and filters come in incompatible families under the same brand. A bike tire or tube has to match your wheel's bead seat diameter, whatever the tire's own marketing calls it. A smart bulb needs a hub that speaks its protocol, and "smart" on the box says nothing about which one. The badge on the box is rarely the answer, and the product page rarely tells you outright. DABA Match adds one line to the retail pages you already shop on: does this fit what you already own? HOW IT WORKS 1. Add what you own in the extension popup — power tools and batteries, cameras, printers, PC parts, a phone, a games console, a fridge, a coffee machine, a vacuum, a smart home hub, a bike, or a car. 2. Shop normally. On a supported retailer's product page, a small panel appears. 3. It says one of three things: fits what you own, doesn't fit, or can't tell. WHAT IT COSTS Your first 5 checks are free — enough to try it on real products you're actually thinking about buying before you decide anything. After that, checking a product needs a pass: A$7.60 for a week, A$10.64 for a month, or A$74.48 for a year — about US$5, US$7 and US$49. Prices are shown in Australian dollars wherever you are, and if you pay in another currency your bank converts at the going rate. Each one is a single purchase, not a subscription. Nothing auto-renews, there is no card kept on file, and there is nothing to cancel — when a pass runs out it simply stops, and buying another is up to you. Passes are sold through Lemon Squeezy, which handles the payment as merchant of record. DABA Match never sees your card details. Building your garage, editing it, and everything the extension stores stay free either way. The verdict is a rule, not a guess. Two products are compatible when they share whichever axis actually decides fit for that category — a battery platform, lens mount, cartridge family, socket standard, filter/pod system, phone case shape, console system or smart home protocol. There is no AI in the decision path, no scoring, no "probably". WHEN IT CAN'T TELL, IT SAYS SO Most compatibility tools would rather answer than be right. This one stays quiet. If a title names two platforms, or a spec two brands both use, or names nothing we recognise, you get "can't verify" instead of a confident wrong answer. A missing answer costs you a lookup. A wrong "compatible" costs you a return trip. WHAT ELSE IT SHOWS Alongside the verdict — never inside it — the panel flags advisory context worth knowing: whether a listing looks like a third-party pack rather than the brand's own, and (for power tools) whether the platform has a known quirk. These never change the fits/doesn't-fit answer. AFFILIATE DISCLOSURE DABA Match participates in affiliate programmes. Where a compatible alternative links out to a retailer, that link may be an affiliate link, and DABA Match may earn a commission on qualifying purchases at no extra cost to you. This never changes a verdict: the fit/doesn't-fit answer comes from the underlying platform alone, the same way whether or not a link happens to be tagged. COVERAGE Seven catalog categories plus car parts — 444 platforms and 1,908 products, covering : - Power tools & batteries — 93 battery platforms, 679 products, from the major cordless brands, including the ones that run two incompatible platforms side by side. - Cameras — 41 lens mounts and battery families, 228 products, including mounts shared by more than one manufacturer. - Printers — 37 cartridge families, 251 products, including cartridges sold under a different number in each region. - PC parts & electronics — 202 platforms, 388 products: desktop socket, memory and storage standards; laptop chargers and batteries by model line; charging cables, cases and screen protectors for 99 phone bodies; and controllers and headsets by games console. - Appliances — 62 fridge filter, coffee pod, vacuum bag/filter and personal-care families, 310 products. - Bikes — 4 wheel-size (bead seat diameter) platforms, 36 products. - Smart home — 5 protocol platforms, 16 products. A hub carries every protocol it bridges, so a bulb, plug, lock or sensor is checked against what your hub actually speaks, not against the logos on the box. Car parts run on a separate, catalog-free path: instead of a platform, the extension reads the year/make/model (or engine) a listing claims and checks it against your garage — see "HOW IT WORKS" above. Works on 34 retailers across 39 domains: the large hardware, electronics, auto-parts and general shopping sites in the United States, in Australia, plus Amazon's Canadian, UK and western European stores. PRIVACY Your garage is stored on your own machine, in the browser's local extension storage. Product matching happens fully offline. The only network call this extension makes is to Lemon Squeezy, to check whether a pass you've bought is active — no other information ever leaves your machine. No account, no tracking, no analytics, no ads. See the affiliate disclosure above for how outbound retailer links work. Need help, contact dabaenterprise@icloud.com
