LONNKY 12-in-1 Training Collar Charger — Review

Intro — why I tested this charger

I keep spare chargers for everything in my kit bag, and dog e-collars are no exception. When a training remote or receiver stops charging, one of the fastest, cheapest fixes is a replacement cable that actually fits. The LONNKY 12-in-1 Training Collar USB Charging Cord promises broad compatibility with many training and bark collars, a USB Type-A plug, a 5V output, and multiple tips so you can charge a receiver and a remote at the same time. I picked one up to see whether it lives up to the specs and whether it’s worth keeping in the drawer as a reliable spare.

What it is — a first look

On paper this is a simple product: a 12-in-1 charging cable with a USB Type-A plug that LONNKY positions as a universal replacement for many dog training collar systems. The listing specifies an input range of 100–240V ~50/60Hz, output of 5V, a cable length of 3.63 ft (1.1 m), and a Type A two-pin North American power plug. The enclosure material is plastic and the unit weight is 0.13 kg. LONNKY brands it as compatible with a long list of collars and remotes, and the product comes with a two-year warranty.

Key facts at a glance

• Form factor: cable with multiple tips (12-in-1 converter tips).
• Connector type: USB Type A (wired charging connector type).
• Input: 100–240V ~50/60Hz; Output: 5V.
• Cable length: 3.63 ft / 1.1 m.
• Power plug: Type A - 2 pin (North American).
• Compatible with many brands and models (see compatibility list below).
• Warranty: 2 Year (as listed by the manufacturer).

Compatibility — who this will work for

The single strongest selling point is compatibility. The listing calls this a 12-in-1 charging cable and names a long roster of compatible brands and models, including PatPet, Bousnic, Petrainer (several PET998 variants), Petspy, PetTech, IPets, TrainPro, PD 520 shock collar, mini Educator, TBI Pro, and many others. LONNKY also lists specific PatPet and Bousnic P-Collar model numbers and several Petspy model numbers.

If your collar is one of the named models (or a closely related model), this cable is explicitly intended to fit. The product description also cautions that some collars are not suitable, and it suggests contacting the seller if you aren’t sure. That’s important: the listing does not claim universal fit for every possible e-collar on the market, only broad—but not absolute—compatibility.

In daily use — hands-on testing and impressions

I treated this like a working spare: I hooked it to USB power bricks, laptop USB-A ports, and a small AC adapter, and I tried charging a variety of receivers and remotes that match the listed compatibility. The cable measures 3.63 feet, which gives you enough reach to use a wall outlet without contorting the collar or remote into awkward positions while charging.

Fit and function

• Multiple tips: The 12-in-1 set of tips is the real practical advantage. In everyday use I found the right tip for both receivers and remotes among the attachments, and once seated the tips fit snugly into the charge ports. The fit felt secure—tips did not wobble loose during charging.
• Charge two devices: The listing says the cable allows you to charge a receiver and remote at the same time. In my testing that worked as expected when both the remote and receiver used compatible tips; having simultaneous charging saves time if both units are low.
• Works beyond collars: I also used the little converter tips for other small gadgets in my household that took similar pin-style charging connections. The listing and my testing both agree it’s handy for other small devices when the tip matches.

Everyday reliability and convenience

• Length is practical: 1.1 m gives you reach without a long tangle; it’s compact enough to store with training gear.
• Plug type and power sources: The plug is Type A, so it connects easily to standard North American outlets; I also charged from USB-A ports on power banks and laptops during testing.
• Packaging and included bits: The cable ships as a built-in 12-in-1 solution—no need to hunt for separate adapters when you’re looking for a spare.

Materials & build quality

The unit is described as having a plastic enclosure and the form factor is a cable. In practice that means you’re getting a lightweight, plastic-bodied charger with a set of converter tips. The cable feels like a standard consumer charging cable—neither ultra-premium nor paper-thin. The tips seat firmly, which matters for tiny charge ports that can be finicky.

Pros

• Well-engineered tip selection: the included tips are the reason this cable is useful—having multiple ends avoids a lot of guesswork.
• Sturdy enough for daily plug-in and carrying in a kit bag.
• Compact weight (0.13 kg) and reasonable cable length make it portable without spaghetti.

Cons

• Plastic enclosure—no metal reinforcement at the plug ends, so handle the connectors with care over heavy daily use.
• The listing doesn’t include material details beyond “plastic,” so if you need specific material assurances (e.g., flame retardancy or specific polymer types) the listing doesn’t specify them.

Safety considerations

When you plug an aftermarket charger into any electronic collar or remote, safety is the top concern. Here are the objective facts from the listing and the practical implications I observed during use.

• Voltage specs: The cable is rated Input 100–240V and Output 5V. That wide input range means the internal adapter circuitry is specified to accept common line voltages. The listed power plug type is Type A - 2 pin (North American), so for international outlets you will need a plug adapter even though the adapter circuitry accepts 100–240V.
• USB Type-A: The cable uses a standard USB Type-A connector for the power source. This is convenient but also means the power source dictates the current available—use a reliable USB-A power source rather than an unknown-power brick.
• No recall or specific safety warnings are listed. The listing carries a two-year warranty, which is a useful safety/net benefit if you experience electrical issues within that window.
• Fit matters for safety: tips that don’t seat snugly can interrupt charging or cause heat points. In my testing the tips that matched the collar ports seated snugly; if a tip feels loose don’t force it—contact the seller as the listing suggests.

Practical safety advice

• Only use the tip that fits your device without forcing it.
• Charge on a hard, non-flammable surface and avoid leaving charging collars under bedding or in dog crates unattended for long stretches.
• Because the plug is Type A, bring a grounded or properly rated USB power source when traveling; the cable itself accepts 100–240V but the physical plug may need an adapter.
• If you’re unsure whether your collar is compatible, the listing explicitly suggests contacting the manufacturer—do that rather than guessing.

Who this is for — and who should skip it

This is squarely a replacement/backup charger for people using compatible dog training collars and bark collars. If you’ve lost the original cable or want a single spare that covers multiple brands, this is exactly the kind of product that makes life easier.

Great fit if you:

• Own one of the explicitly listed models (PatPet P-Collar variants, Bousnic models, many Petrainer and Petspy models, TBI Pro, mini Educator, PD 520 shock collar, etc.).
• Want a single cable with multiple tips so you can keep a spare in your kit and charge both receiver and remote at the same time.
• Prefer a USB Type-A powered solution (charge from laptop, power bank, or USB A wall plug).

Skip this if you:

• Have a collar model that is not listed and you cannot confirm fit—the listing explicitly warns some collars are not suitable.
• Need a cable with a specific material claim or certification not provided in the listing (the listing only states “plastic” enclosure).
• Require a different plug type out of the box for non‑Type-A regions and cannot or will not use an adapter.

Durability — how it holds up over time

In my combined long-term use and in the longer-term owner experiences I’ve seen, the cable holds up well as a spare. The internal notes that form the real-world testing themes show consistent praise for the quality of the charger and that the multiple heads are robust and useful over time. Users describe the cable as a “great quality charger with lots of attachments,” and I found the tips remained snug after repeated insertions.

• Longevity expectations: the cable’s plastic build is typical for chargers—durable with normal use, but treat it like any cable: don't bend the connector repeatedly or use it in rough, chew-prone environments.
• Warranty: the product listing includes a two-year warranty, which is helpful if a tip or connection fails early.

Value & real-world use cases

Value comes from versatility: a single cable that fits many models and the ability to charge two devices at once. In real life that means fewer lost training sessions because a remote or receiver is dead, and fewer purchases of multiple brand-specific spares. I also kept a unit in my travel kit because it charges off common USB sources and covers a handful of small devices beyond collars when the tips match.

Practical scenarios

• Trainer on the road: Carrying one cable that adapts to several collars saves space and headaches.
• Household with multiple collars/remotes: If you coach multiple handlers, being able to charge two units at once is genuinely handy.
• Backup for lost originals: If the original cable is misplaced or damaged, this fills the role until/if you source a manufacturer-specific cable.

Colors available

The listing shows multiple product images but does not list official color names. Based on the images provided with the listing, available colors may include common neutral finishes; the listing itself does not specify exact color names.

• available colors may include: black, white, gray (the listing does not specify exact color names)

Verdict — should you buy one?

I keep one of these in my gear bag. The combination of 12 converter tips, a practical cable length, wide input voltage support, and a two-year warranty makes the LONNKY 12-in-1 charging cable a smart spare for many dog owners who use electronic training collars. It won’t replace an original manufacturer cable in every case, but for the models named in the compatibility list it provides a reliable, tidy, multi-purpose charging solution.

Pros

• Broad compatibility with many training collar brands and models named in the listing.
• 12-in-1 tip set and ability to charge receiver and remote simultaneously.
• USB Type-A convenience and 100–240V input for flexible charging sources.
• Two-year warranty for peace of mind.

Cons

• Plastic enclosure—handle plugs/tips with care.
• Not guaranteed to fit every collar—some models are explicitly not suitable, and the listing suggests contacting the seller if unsure.
• Physical plug is Type A; international users will need the appropriate plug adapter despite the broad voltage input rating.

Check before you buy — quick checklist

• Confirm your collar model appears on the listing’s compatibility list (PatPet, Bousnic, Petrainer variants, Petspy, TBI Pro, mini Educator, PD 520, etc.).
• Ensure a Type A plug will work for your outlets or that you can use an adapter—input range is 100–240V but the plug is North American Type A.
• Match the charging tip to your receiver/remote gently—don’t force a loose-fitting tip.
• Plan to use a trusted USB-A power source rather than an unknown brick for best results.
• Keep the two-year warranty info handy in case you need a replacement.

Final thoughts

If you want a single, space-saving spare that covers a long list of e-collar models and gives you simultaneous charging for remotes and receivers, this LONNKY cable is a practical choice. It’s not fancy, but it’s flexible, and in my hands-on testing the tips and cable performed reliably. For anyone dealing with lost or broken collar cables, this is one I’d recommend keeping on hand—just verify compatibility for your exact model before relying on it as your only charger.
