Sharkwill E90 Microchip Scanner Review

Intro — why I tested the Sharkwill E90

I’m The Pet Dude: I rescue, foster, and outfit pets, and I like gadgets that make reunions faster. Microchip scanners are one of those under-the-radar tools every shelter volunteer, dog walker, and neighborhood rescuer should have on hand. The Sharkwill E90 is a compact, handheld RFID microchip reader that promises to read the common international standards, store chip IDs, and transfer that data to a computer via USB-C. I spent time pulling together the manufacturer specs and long-term owner experiences so you can decide whether this is the practical scanner for your needs.

What it is — first look

The Sharkwill E90 is a small, glossy, rectangular handheld microchip scanner from Sharkwill (model E90). The listing gives a product size of 3 inches x 1.5 inches x 0.5 inches and lists the material type as RM and finish as glossy. It ships with a USB cable and advertises a built-in rechargeable battery charged by USB.

• Supported chip types: ISO11784 / ISO11785 / FDX-B and EMID, ID64 pet microchips. The listing specifically notes it does NOT read AVID microchips.
• Display: high-brightness OLED with backlight for low-light reading.
• Storage: the listing references built-in storage; product copy alternately mentions "128/500 pieces" and the bullet points emphasize support for 128 pieces of information storage.
• Connection: Type-C to USB cable included; listing says stored data can be uploaded to a PC via USB.
• Scanning range notes from the listing: several specific callouts are given, including distances for reading through some labels (e.g., 2–12mm glass tube label >8cm/3 inch; 30mm ear label >20cm/7.8 inch).
• Included component: USB cable.

In daily use / hands-on testing

Short version of real-world performance: the Sharkwill E90 reads the supported chips reliably and is pleasantly pocketable, but its data-upload behavior and documentation are the two main practical pain points people encounter.

Scanning pets

When you power it on and sweep the reader over a microchipped pet, the OLED display shows the chip ID number. The bright backlit display helps in dim garages or at night, which is useful when you're trying to confirm a lost dog or stray cat. Multiple owners who use this device describe it as easy to use with a single-button interface — press the button and scan.

Storage and transferring IDs

The listing claims the device stores chip IDs (the product copy mentions "built-in storage of 128/500 pieces," while the specification bullets emphasize 128 pieces). It also says you can upload stored data to a PC using the included Type‑C to USB cable. Experiences are mixed in practice: some owners successfully transfer readings to a computer (one described holding the button for a few seconds while connected and seeing numbers appear in a text editor), while others connected the cable and only saw that the unit was charging and could not access stored data at all. The instructions that come with the unit are frequently described as incomplete, so expect to experiment or troubleshoot if you need to extract stored records.

Portability and daily carry

The E90 is compact (3 x 1.5 x 0.5 inches) and glossy finished. That small footprint makes it easy to keep in a volunteer kit, backpack, or glove compartment. Because it’s rechargeable via USB, you don’t need to keep spare batteries on hand — just remember to recharge before long searches. Owners appreciate that it’s rechargeable and portable, calling it a handy, inexpensive reader to check whether an animal is chipped.

Materials & build quality

The listing lists the material type as RM and a glossy finish. The size and rectangular shape make for a tidy, pocketable unit. Build impressions from owners are generally positive: several people describe it as a quality, easy-to-use handheld reader that scans chips from different manufacturers within the supported standards.

• Design: one-button operation—simple interface but also limiting if you want advanced file management without clear controls.
• Display: OLED with backlight that helps when you’re scanning in low light.
• Included cable: USB Type-C cable is included for charging and (in theory) data transfer.
• Finish & feel: glossy rectangular unit that slips into a pocket; owners report the small black variant (marketing color labeled "No-bluethooth") is what many received.

Safety considerations

Microchip readers are low-risk devices, but there are a few practical safety and fit considerations to keep in mind.

• Read compatibility: the E90 supports ISO11784/ISO11785/FDX-B and EMID/ID64 microchips — it will not read AVID microchips. If you rely on reading AVID chips in your area, this unit isn’t appropriate.
• Electrical safety: the unit has a built-in rechargeable battery charged via USB; the listing does not specify battery chemistry or safety certifications. The included USB cable charges the unit, and multiple owners report it shows charging when connected to a computer or phone. If you plan to use the device around water (wet animals, rainy rescues), keep the USB port and device dry — the listing does not claim waterproofing or water resistance.
• Data & workflow safety: the scanner displays the chip number only; it does not display a pet’s name or owner info. Because owner contact details are not stored on the device, you’ll need to use the chip number to look up the registration on the appropriate microchip registry. The listing notes storage and upload capability, but owners report inconsistent success transferring data — plan to photograph the display as a quick backup if you can’t immediately upload.

Who this is for — and who should skip it

Who I recommend it for

• Neighborhood rescuers, volunteers, and small shelters who need an inexpensive, portable scanner that reads FDX‑B and EMID chips.
• Pet parents who want to check whether their pets are chipped and to read the chip number quickly.
• People who value a rechargeable unit with a bright OLED display for low‑light scans.

Who should skip it or consider alternatives

• If you need to read AVID microchips: skip the E90 — the listing explicitly says it does not read AVID microchips.
• If you rely on flawless, out-of-the-box USB data uploads and clear instructions for file management: the E90’s documentation is described as incomplete by multiple owners and some units fail to present stored data to a computer. If USB upload is mission-critical to your workflow, consider scanners with robust vendor support or explicit, proven PC integration.
• If you want a multi-button interface with in-device scrolling and advanced record management: the E90’s single-button design limits on-device control of stored records in real use.

Durability, maintenance, and troubleshooting

• Durability: owners do not report breakage as a common issue. The glossy finish and compact body are practical for carry, but the listing does not provide drop or ruggedness claims.
• Cleaning: the listing does not include cleaning instructions. As a general precaution, keep liquids away from the USB port and wipe the outside with a dry or slightly damp cloth; the listing does not claim waterproofing.
• USB connection problems: some owners say the scanner only indicates charging when connected and does not expose stored files to a computer. One owner described a method that worked for them: connect the device, open a text editor such as Notepad, ensure the cursor is active, turn on the reader and hold the button to cause the reader to output the chip number into the editor. Other owners tried many cables and devices without success. Be prepared to test different cables and computers, and know that results may vary.

Value and real-world tradeoffs

The E90 positions itself as a compact, rechargeable microchip reader with on‑device storage and PC upload capability. Owners praise its ability to read a variety of non-AVID chips and appreciate the bright OLED for night work. The tradeoff is that the documentation and USB data transfer behavior are inconsistent across units; some owners had a painless workflow while others never managed to extract stored data.

• Good value if: you primarily need a handheld scanner to read chip IDs in the field and don’t require reliable, feature-rich PC integration straightaway.
• Less good if: you plan to rely heavily on the device for database uploads and expect plug-and-play PC support with clear instructions.

Tips & tricks I picked up from owners

• If you want to preserve a scan quickly, keep your phone camera ready to snap the display — some owners reported the displayed number doesn’t stay up very long on-screen.
• Try different Type‑C cables and different computers if you run into upload issues; some owners could get data into a text editor by connecting and holding the button while the reader was on and the editor was active.
• Keep in mind the supported chip list and the explicit "DO NOT READ AVID MICROCHIP" warning in the product copy — don’t expect AVID compatibility.

Colors and model notes

The listing default color is labeled "No-bluethooth." Multiple owners reference receiving a small black unit described as "no Bluetooth." Based on the listing copy and owner notes, colors available may include:

• No-bluethooth (black)

Verdict

The Sharkwill E90 is a handy, pocketable microchip scanner that does the core job well: it reads ISO11784/11785/FDX‑B and EMID/ID64 microchips and shows the chip ID on a bright OLED display. For volunteers, rescuers, and pet parents who need an inexpensive, rechargeable scanner to check pets quickly, it delivers real-world value. Its portability, rechargeable design, and support for common chip standards are the product’s strengths.

The primary caveat is workflow: the listing claims stored records and USB upload to PC, but owner experiences are mixed and the included documentation is commonly described as incomplete. If you need reliable, out-of-the-box PC integration, or you must read AVID microchips, this is not the right device. Otherwise, it’s a useful, budget-conscious tool to have in your kit.

Check before you buy — quick checklist

• Confirm the chips you need to read are FDX‑B/EMID/ID64 / ISO11784/11785 (this unit will not read AVID chips).
• Decide whether on‑device storage plus USB‑C upload is required for your workflow; be aware some owners struggled to extract stored data despite the listing claim.
• Plan for a small, glossy handheld device (3 x 1.5 x 0.5 inches) and check that size fits your carry kit.
• Expect to troubleshoot USB connections on some computers; try multiple Type‑C cables and a text editor method if necessary.
• Keep a camera ready to capture the displayed number as a backup if you can’t immediately upload stored data.

Final thoughts

I like the Sharkwill E90 for what it is: a compact, rechargeable scanner that reads a wide set of common pet microchips and is easy to carry during walks, home checks, or rescue sweep days. It won’t replace a clinic-grade or multi-standard reader built for professional shelters that require guaranteed PC integration and extensive device-side record management, but for neighborhood rescuers and pet owners who need a reliable way to read chip IDs on the go, it’s a solid, affordable pick — provided you accept the tradeoffs around upload and documentation.
