While they come from the same company, you’ll quickly learn that Hart batteries are not compatible with Ryobi tools and even using an adapter can be risky.

Back in the days when disposable batteries were your only source of portable power, you had to accept whatever brand you could find at the store. Nowadays, at least with cordless power tools like those from Ryobi, we have the opposite problem: Battery packs are rechargeable, but you can only use the specific packs manufactured by the tool’s manufacturer. If you have a sudden need for a Ryobi battery but there isn’t a Home Depot nearby to buy one, what are you supposed to do?
Despite the specificity, you might still try bending the rules. At first glance, a Hart tool battery may seem a sufficient substitute considering that Hart and Ryobi power tools are made in the same factory. As Hart power tools are readily available at Walmart, it makes for a convenient solution. Sadly, this is a problem that a Walmart visit can’t remedy. While Hart batteries may be conceptually similar to Ryobi’s packs, they can’t fit on to Ryobi tools or deliver any power. If you’re truly determined to use a Hart battery on a Ryobi tool, it is technically possible to do so through the use of a third-party battery adapter. However, using unsanctioned accessories such as these may end up causing more problems than they’re worth.Hart batteries will not fit on Ryobi tools
Every hardware brand uses its own proprietary technologies when manufacturing its batteries and the tools that receive them. Many of these batteries have slight similarities, such as the comb-shaped panels on top and the rails used for securely connecting to a tool’s receiver. Ryobi, however, is a bit of an outlier in that department, with a battery pack format so different from anything else on the market that there’s genuinely no way any other brand could copy it, Hart included.
Let’s compare batteries from both sides, specifically a Hart 20V 4Ah battery and a Ryobi 18V ONE+ 4Ah battery. The Hart battery’s format is closer to the norm, with a flat top, recessed panel, and several divots that conceal the power transfer terminals. This is all connected to a tool via straight-line connector rails. The Ryobi battery, meanwhile, doesn’t have a flat top at all, instead opting for a distinctive stalk that juts upward. That stalk is covered in terminals, which connect directly into a cylindrical receiver nook on a Ryobi tool. This is locked into place by fasteners located on the stalk’s base.
Hart and Ryobi battery designs are simply too different to have any kind of crossover. Since Ryobi tools are built to receive batteries directly instead of having them slide on, a Hart battery’s connector rails would have nothing to latch onto. Even if you could attach a Hart battery to a Ryobi tool somehow, the lack of upward terminals means there’s no way for the battery to deliver power.Unofficial adapters are available, but are not recommended
With these batteries as drastically different as they are, there is no way for a Hart battery to natively attach to a Ryobi tool. However, as with other industries with numerous exclusive brands, there are user-generated solutions to these kinds of problems. In this instance, the alleged solution would be to use an unofficial battery adapter. This is an accessory manufactured by a third-party specifically designed to facilitate a connection between two disparate tool brands’ products. These adapters are all over major commerce platforms like Amazon and eBay.
The reason we call this an « alleged » solution is because using any kind of unofficial accessory with your power tools, and especially one related to power management, could be a potential recipe for disaster. All power tool batteries, Hart’s included, contain an internal circuit board for directly interfacing with a connected tool and optimizing the flow of power for safe usage. Connecting a Hart battery to a Ryobi tool via an adapter circumvents that circuit board and forces energy to flow in an unoptimized manner.
With power flowing unfettered, you could either end up with underpowered, underperforming Ryobi tools, or worse, a dangerous overload of energy that results in the motor completely burning out. Additionally, Ryobi won’t replace your batteries or tools should they suffer permanent damage from using an adapter, as using an unofficial accessory is a violation of both warranties.

Fastest PHEVs you can actually buy, from McLaren Artura to Lamborghini Revuelto, pushing hybrid speed and power to supercar extremes.
Hybrids are getting out of hand. Weren’t they supposed to just be fuel efficient and good for the environment? That’s what we thought was going to happen when the Prius was king, but today, we have hybrids that bring the combustion engine to new heights. That’s especially true for plug-in hybrids or PHEVs, which have larger batteries for an even higher electric boost.
In fact, electric motors are so good that they counter several ICE drawbacks. For example, they eliminate turbo lag, provide naturally aspirated engines with turbo-like torque, and even allow driving on the battery to lower emissions and protect the engine. Still, you’re here to learn how fast PHEVs have become today. The answer is ballistic. For instance, the Koenigsegg Gemera has a 2,300-hp PHEV powertrain, consisting of a 1,500-hp, 5.0-liter twin-turbo V8, and an 800-hp electric motor. As a result, it reaches a top speed of 248 mph and sprints to 62 mph (100 km/h) in 1.9 seconds!
However, in this piece, we won’t be listing hypercars made of unobtanium. Models like the Gemera are either too limited or already accounted for. Instead, we’ll give you the fastest PHEVs you can really buy in dealerships today — just make sure you enter with a sufficiently deep pocket. Before you do that, enjoy this electron and gas cocktail!McLaren Artura (205 mph)
Opposing the current norm, McLaren launched its first PHEV in 2023 not as a high-end model, but as an entry-level supercar. But don’t let that fool you into thinking it’s anything less brutal than the firm’s other offerings. Not only that, but the McLaren Artura teaches you to embrace the hybrid.
Yes, the Artura packs a small-ish 3.0-liter twin-turbo V6 as opposed to the 4.0-liter twin-turbo V8 in other McLaren models. Still, it’s accompanied by a compact, 94-hp axial flux electric motor, which helps it produce 690 hp and a meaty 531 lb-ft of torque at just 2,250 rpm. The electric motor sits inside the eight-speed dual-clutch transmission, meaning it acts as a « torque filler », virtually eliminating turbo lag. The motor draws electricity from a 7.4-kWh battery, which provides an EPA-rated 11 miles of range on a full charge. But who cares when you have a supercar that reaches 62 mph (100 km/h) in 3 seconds, 124 mph (200 km/h) in 8.3 seconds, and has a top speed of 205 mph (330 km/h)?
And the Artura isn’t only a one-trick pony — it also has a very advanced chassis. Notably, it utilizes the brand-new McLaren Carbon Lightweight Architecture (MCLA), which is lighter than before, resulting in a curb weight of just 3,303 pounds for the coupe. It also has an electronic differential at the back, which provides torque vectoring, and a rear spoiler/diffuser that generates downforce. Did we mention it’s RWD-only? As a result, the Artura dances through the corners and feels cohesive, allowing both amateur and professional drivers to have fun behind the wheel.Bentley Continental GT Speed (208 mph)
Want a mega-fast PHEV car that doesn’t follow the supercar formula? There is really only one option — the Bentley Continental GT Speed. It’s the company’s most powerful automobile, packing an astonishing 771 hp and staggering 738 lb-ft of torque. That power comes from a 4.0-liter twin-turbo V8, aided by an electric motor in the transmission to eliminate turbo lag. Yes, it’s not the old GT Speed’s W12, but the latest Continental GT Speed shuts down skeptics with an approximately 120-hp gain over the old W12. Because power goes to all four wheels, this 5,421-pound behemoth reaches 60 mph in 3.1 seconds and won’t stop until the needle shows 208 mph (335 km/h). Why is it that heavy, you might ask? It packs a relatively big 25.9-kWh battery for a useful 40-mile range.
We also dig the meaner looks. Bentley did a great job giving its luxurious GT sportier styling while keeping it recognizable. Step inside, and that’s where the real magic happens. The cabin has that classic Bentley look to it, but with more tech than ever before. Fortunately, Bentley also implemented physical buttons, but we aren’t sure about the use of plastics in some areas.
Still, the driving experience doesn’t suffer. This mega-GT comes equipped with new dual-valve dampers for a smoother ride and 48V anti-roll control that keeps the car level in the corners. Oh, and because the battery is mounted behind the rear axle, the GT Speed has an almost ideal 49:51 weight distribution, resulting in more balanced and nimble handling.Ferrari SF90 Stradale (211 mph)
Ferrari has been making great progress with electrified powertrains since its first hybrid, the LaFerrari. Well, the SF90 Stradale is also a pioneer. It’s the first Prancing Horse model with a plug-in hybrid powertrain, and it hits all the right notes. See, even without the electric bits, the engine is Ferrari’s most powerful V8 in history; the 4.0-liter twin-turbo unit produces a prodigious 769 hp.
Still, the SF90 Stradale also has three electric motors that bump the output to a whopping 986 hp and an Earth-shattering 590 lb-ft of torque. One electric motor is sandwiched between the engine and the eight-speed dual-clutch transmission to remove turbo lag, while the two others sit on the front axle. Yup, the SF90 Stradale is AWD, meaning it launches off the line like an EV. 60 mph arrives in just 2.5 seconds, and reaching 124 mph only takes 6.7 seconds. Top speed: an eye-watering 211 mph (340 km/h).
This is a Ferrari, though, so performance figures are only part of the story. Considering the electric bits, the SF90 Stradale is pretty light at around 3,900 pounds. It also has advanced aerodynamics with a « shut-off Gurney » flap that activates when the car corners, delivering a staggering 860 pounds of downforce at 155 mph for maximum stability. Unsurprisingly, the SF90 Stradale handles corners with poise and also delivers on the engagement front with good steering and a sonorous V8 noise. Ah, yes, its small 6.5-kWh battery only provides a 15-mile range. Still, it’s enough to avoid waking your neighbors before you have a blast early in the morning.Lamborghini Temerario (213 mph)
People want as much power as automakers can give, so of course, almost every engine today is turbocharged. But they also want high-revving naturally aspirated engines that build excitement. The two don’t exactly go hand in hand.
Or do they? For its latest entry-level supercar — if you can call it that — Lamborghini did the impossible. The Temerario has a 4.0-liter twin-turbo V8 that produces a staggering 789 hp, but it also revs to 10,000 rpm! In fact, the maximum power figure is available in the stratospheric range of 9,000 to 9,750 rpm. The massive 538 lb-ft of torque is also available from a relatively high band of 4,000 to 7,000 rpm. This thing wants to be revved. In fact, it revs higher than the naturally aspirated V10-powered Huracán. But Lambo took things even further by implementing three 148-hp electric motors. One is connected to the engine for torque fill, and the other two sit on the front axle for AWD. The full output is 907 hp and 774 lb-ft of torque. 0-62 mph: 2.7 seconds. Top speed: 213 mph.
So, as you’d imagine, the Lamborghini Temerario packs a whole lot of drama. It produces unrelenting power and torque at any rpm, with the PHEV system working in perfect harmony. The Temerario also corners and stops impressively and even has a drift mode if all you want is some shenanigans. Ah, yes, it only has a tiny 3.8-kWh battery that provides just 5 miles of range. But, honestly, that’s great news, because a bigger battery would’ve just added unnecessary weight and possibly spoiled the experience.Lamborghini Revuelto (217+ mph)
Do you find the Temerario not exciting enough? Well, climbing up the Lambo ladder brings you to the Revuelto — the brand’s first V12 plug-in hybrid supercar. Or shall we say a hypercar, because its PHEV powertrain produces a staggering 1,001 hp. That’s enough for a 0-62 mph sprint of 2.5 seconds and a top speed higher than 217 mph.
Yup, the pace of the Lamborghini Revuelto is truly epic, but this raging bull also scores high on the experience front. Just the thought of having a 6.5-liter naturally aspirated V12 stirs emotions, let alone one that produces an astonishing 814 hp on its own and revs to 9,500 rpm. As you’d expect, the sound it produces is pure Italian V12 drama. The coolest thing about the Revuelto is that the electric bits don’t neuter the experience. In fact, they enhance it. Thanks to the instant surge from the three electric motors, the Revuelto has a whopping 1,044 lb-ft of torque. That’s almost double the 531 lb-ft figure of its predecessor, the Aventador, and higher than most turbocharged engines. So, it picks up like a turbo, but without any lag, and the fantastic naturally aspirated noise still pierces your ears.
Yet, being Lambo’s flagship, the Revuelto also impresses in other areas. It has a carbon tub Monofuselage that provides ridiculous rigidity of 40,000 Nm per degree, semi-active suspension, carbon ceramic brakes, and active aerodynamics with 66% more downforce than the Aventador. Oh, and the same 3.8-kWh battery as the Temerario for only 5 miles of range. Not that you asked.
