A Portable Projector Just Got Recalled for the Same Reason So Many Other Gadgets Have This Year: The Battery Inside It

BenQ is recalling its GV31 portable projector after reports the built-in lithium-ion battery can overheat during charging. It is a small recall by the numbers, but it is the latest reminder that any rechargeable gadget in your house, not just phones and laptops, deserves a look at how and where it charges.

What BenQ is recalling and why

On July 30, 2026, BenQ America recalled its GV31 portable projector, a white, circular unit with a built-in speaker that runs on a rechargeable lithium-ion battery. The Consumer Product Safety Commission says the battery can overheat, posing a risk of fire and burn injuries. BenQ has logged at least one report of a projector overheating in the US, and the recall covers roughly 1,250 units sold domestically plus another 243 in Canada, according to Health Canada's recall notice.

The fix is a free battery replacement and firmware update through BenQ, not a full refund, which tells you the company believes the problem lives specifically in the battery pack rather than the projector's design. Owners are told to stop using the projector immediately and register through BenQ's recall page rather than keep charging it while they wait.

By recall standards this is a small one. What makes it worth a homeowner's attention is not the unit count, it is the pattern. This is at least the fourth or fifth lithium-ion battery recall CPSC has posted in 2026 involving a household electronic that people plug in and walk away from, joining hand warmers, heated blankets, magnetic phone chargers, and cordless yard tools.

Why lithium-ion batteries keep showing up in fire recalls

Lithium-ion cells store a lot of energy in a small package, which is exactly what makes them useful in a portable projector, a power bank, or a cordless tool, and exactly what makes a manufacturing defect dangerous. If a cell develops an internal short, whether from a manufacturing flaw, physical damage, or a bad charging cycle, it can enter thermal runaway: the cell heats itself faster than it can shed heat, and that heat cascades to neighboring cells.

None of that requires a faulty outlet or bad house wiring to happen. It is a product-level failure. But the house electrical system is where the consequences show up, because these devices are almost always plugged into a wall outlet, a power strip, or a USB hub when the failure occurs, often overnight or while nobody is in the room.

That is the useful, boring habit worth building: treat any device with a built-in rechargeable battery, not just phones, the way you would treat a space heater. Charge it on a hard, non-flammable surface, not on a bed or couch. Do not charge it under a stack of papers or inside a bag. And do not leave it charging on a power strip that is also feeding half the other electronics in the room.

What this means for your home's outlets and circuits

A single overheating battery recall is a manufacturer's problem to fix. But if you have noticed a warm wall plate, a power strip that runs hot, or a breaker that trips when several charging devices are plugged in at once, that is a separate and real electrical issue worth having a licensed electrician look at, especially in rooms like home offices or media rooms where projectors, laptops, monitors, and chargers tend to cluster on one circuit.

Older Connecticut homes, particularly ones built before the 2000s, were not wired with today's density of chargers, streaming boxes, and rechargeable gadgets in mind. A circuit that was fine for a lamp and a TV in 1995 can be working harder than it looks with a modern entertainment or office setup layered on top of it.

This is also a good moment to check that outlets feeding a media room, office, or kids' bedroom, anywhere multiple devices charge overnight, are on a circuit with working GFCI or AFCI protection where code calls for it. That protection will not stop a defective battery from overheating, but it does reduce the chance that an overloaded or damaged circuit adds a second point of failure.

What to actually do this week

If you own a BenQ GV31, stop using it and register for the free battery replacement at BenQ's recall page before you plug it in again. Do not assume yours is fine just because it has not overheated yet.

For every other rechargeable device in the house, a quick walk-through takes ten minutes: unplug anything charging on a bed, couch, or pile of clothing, spread out devices that are currently sharing one power strip, and note any outlet or plug that feels warm to the touch. Warm to the touch, on its own, is worth a call to an electrician, not a wait-and-see.

5 charging habits worth adopting for any rechargeable device

Whether it is a projector, a power bank, an e-bike, or a cordless tool, the same handful of habits cut down real fire risk, recall or no recall.

1. Charge on a hard surface: Never on a bed, couch, or rug, where heat cannot dissipate and a fire has fuel right next to it.
2. Do not charge unattended overnight if avoidable: Most reported thermal-runaway incidents happen while the device is charging and nobody is nearby to notice heat, smoke, or smell.
3. Spread devices across outlets: A single power strip loaded with a projector, laptop charger, monitor, and phone charger runs hotter than any one of those devices alone.
4. Register your product with the manufacturer: Recall notices go to registered owners first; an unregistered device can keep charging for months after a recall is issued.
5. Watch for swelling, smell, or heat: A battery that looks puffy, smells odd, or is noticeably warm to the touch should be unplugged and stopped, not monitored.
6. Have a licensed electrician check high-use circuits: If a room's outlets or breakers already show strain from charging gear, that is worth fixing before you add more devices to it.

Frequently asked questions

Is the BenQ GV31 recall a fire hazard or just a warranty issue?

It is a fire and burn hazard recall through the CPSC, not a routine warranty program. BenQ is offering a free battery replacement, and owners are told to stop using the projector until that repair is done.

Do I need an electrician if I own one of these projectors?

No, the fix here is with BenQ directly through their recall page. An electrician's role is separate: checking whether the outlets and circuits you use for charging devices in general are handling the load safely.

Are lithium-ion battery recalls actually becoming more common, or does it just seem that way?

CPSC has posted several lithium-ion battery recalls through 2026 across very different product categories, from hand warmers to heated blankets to power banks to cordless tools. The common thread is the battery cell itself, not the electrical system it plugs into.

What is the single biggest mistake people make charging rechargeable devices at home?

Leaving them charging unattended on a soft, flammable surface like a bed or couch overnight. That combination, a defective or damaged cell plus fuel nearby and nobody around to notice a problem, is behind most serious incidents.
