The ‘Most Advanced’ Chromebook Has an AI Chip That’s Just Pure Overkill for ChromeOS

The ‘Most Advanced’ Chromebook Has an AI Chip That’s Just Pure Overkill for ChromeOS

What do you need your Chromebook to do for you? If you’re like most people who buy the cheaper ChromeOS-based laptops, you want it to access a browser and—if you’re feeling particularly spicy—maybe a few select Android apps. The most important elements for these lightweight clamshells are normally whether it can load webpages fast, has a long-enough battery, and if it has a quality display for your average Netflix and chill session. With its latest update, Google and Lenovo are asking consumers if they are willing to drop more money on a Chromebook that’s more powerful to potentially run a few AI apps on-device.

The $650 Lenovo Chromebook Plus 14 doesn’t have your average low-end chip made for lightweight PCs. The laptop sports 16GB of RAM alongside MediaTek’s Kompanio Ultra chip. It’s an 8-core processor designed specifically for Chromebooks. On paper, the Chromebook Plus 14 has some impressive specs, including an 11-core, ray tracing-capable GPU for those few games or 3D apps on Chromebook that support enhanced, realistic lighting effects. It should also supply enough juice to support up to two 4K external displays, plus it has Wi-Fi 7 connectivity.

The Chromebook Plus 14 seems designed to compare with today’s AI PCs, specifically thanks to its NPU, or neural processing unit. It’s a portion of the chip designed to process AI-related tasks. MediaTek said the NPU hits 50 TOPS, or trillions of operations per second. That number offers a rough estimate of how well it can handle simple AI tasks. Most “AI PC” chips from companies like Intel and AMD can support 45 TOPS. As for what AI features are available at launch, that’s a little more disappointing. Lenovo’s laptop will get exclusive capabilities that automatically group your browser tabs, whether they’re your Google Docs or internet searches. It should be smart enough to consolidate your tasks into their own groups. If you’re the type to have too many tabs open simultaneously, it could prove an easy way to get them all contained.

Otherwise, the only other exclusive software feature is AI image editing in the Gallery app. It’ll let you use Magic Eraser to remove objects in an image’s background without needing an internet connection. The system is lacking any on-device Gemini chatbot. While Google didn’t confirm what was coming next for Chromebooks, it implied we could eventually see some Gemini Nano language model integration on Chromebook Plus. Is that something we’re really looking for? Considering how limp Microsoft’s Copilot has been on PC, it’s not the kind of feature we’re truly jonesing for.

All Chromebook Plus models will get a few more features to add on to last year’s updates. The recently introduced “Quick Access” key, which on some models replaced Caps Lock, can now generate AI images. Users can also access a “Help me read” function to break down a web page or document into more condensed bullet points with AI-generated text. Chromebooks, including non-Plus models, will be able to perform Google Lens image searches by either hitting the on-screen launcher button or using the screenshot tool. Google has been on an AI kick these past few years, and it’s still promoting that you’ll get a full year of Google One premium subscription with a handy 2TB of cloud storage.

These features aren’t anything we haven’t seen before on Google’s phones or other devices. Chromebooks generally don’t need anything truly special, since most people who buy one just need it for the sake of accessing browser- or cloud-based apps. Samsung’s Galaxy Chromebook Plus from last year was already too expensive at $700 despite its light frame and pretty AMOLED display. Lenovo’s Chromebook Plus 14 sports an OLED screen and what Lenovo claims is some of the longest battery life of any Chromebook—17 hours, though that’s in video streaming tests. It’s also the only Chromebook that supports Dolby Atmos audio through its quad speaker system. The Chromebook 14 Plus is the most PC-like of any Chromebook ever made, but without broader app support, it can never match the versatility of other laptops running Windows 11 or Linux. If you’re entrenched in the Google ecosystem and don’t mind cloud-based work, most modern Chromebooks of even moderate quality will serve you well. Lenovo’s latest seems to sit somewhere between great and overkill, but we’ll need to do our own tests to see whether you should want a multimedia Chromebook, especially if you don’t care a lick for Google’s AI features.

If you were thinking of seeing Minions & Monstersor at least taking your kid to see it, here’s something to sweeten the pot: George Lucas is in it.

Illumination head Chris Meledandri broke the news in a recent Collider interview, where he revealed the Star Wars creator is secretly a fan of Despicable Me’s chatty champions. “It was such a thrill to learn and share that with the team,” said Meledandri, “He’s among a very small group of people who the entire studio shares a level of respect for that is just off the charts.” Given Lucas’ affection for funny little guys, it makes sense that he loves the biggest little guys of our current movie era.

Now that they knew they had Lucas in their corner, the team decided what the hey, get him to do a voice for the movie. Meledandri said an “idea for a character” was born that fit the bill, and they got “a fast yes” when it was pitched. At time of writing, Illumination’s quiet on who Lucas will be, but it’s worth noting that Minions & Monsters takes place in the 1920s as the crew try to make their own movie. Lucas’ love for older films is apparent in Star Wars and Indiana Jones, so maybe he’ll be a director that ends up getting trampled by the Minions. Maybe he’ll even be one himself who just looks like a little yellow George Lucas, that’d be fun.

Look for Minions & Monsters to hit theaters on July 1.

With electricity costs soaring, home batteries have never looked so attractive. Whether you want to store the excess generated by your solar panels or simply buy electricity at the cheapest possible rate to use later when power is most expensive, a home battery can help. It’s never been easier to get a home battery installed, but this rapidly expanding market can be confusing, and there are several things to consider before you buy.

I’ve spent months researching home batteries, chatting to folks who use them, and then having one installed myself, and I have tips for anyone interested in getting a home battery of their own.

Why Would You Want a Home Battery?

There are several reasons you might want to invest in a home battery, and they are not mutually exclusive:

  • You want to store excess power from your solar panels.
  • You want to live off-grid.
  • You want to guard against power outages.
  • You want to buy electricity at a cheap rate and store it for use later.

Home batteries are a win-win, potentially benefiting power companies too, because battery storage is an essential part of grid balancing and can help manage and make the most of the intermittent power generated by renewables (solar, wind, waves).

How Do Home Batteries Work?

A home battery is like a big power bank for your home. But rather than lithium-ion, they tend to be lithium iron phosphate (LFP or LiFePO4), because it is safer, more durable, and less prone to thermal runaway. In other words, less likely to overheat and burst into flames. There are a few manufacturers working with sodium-ion (Na-ion) batteries, which are potentially cheaper, more environmentally friendly (they don’t require lithium), and perform better in the cold, but they are also larger and don’t last as long.

Home battery technology is often the same as you’ll find in electric vehicles. Some folks have even suggested employing EV batteries as home batteries. But there are potential issues with that, not least finding your car battery drained in the morning. EVs are also driving the technology forward toward solid-state batteries, which are smaller for the same capacity, safer as they don’t have liquid electrolytes inside, and longer lasting.

Many home batteries come in modular systems, so you can add the capacity you want, but they require an inverter to convert the DC (direct current) power stored to AC (alternating current) power you can use. Folks with solar panels, or those who plan to add them in the future, should opt for a hybrid inverter, which can also convert the power from the panels for use or storage.

Inverters have different power ratings in kilowatts (kW) that dictate how much power you can draw at any given moment. Households with modest needs may get by with a 3.6-kW inverter, but that limits your continuous draw to 3.6 kW. They usually have a peak load capability that goes higher, enabling you to pull more for a brief period. If you have high-demand appliances like an EV charger or heat pump, you will want at least 5 kW, and folks with larger demands or larger batteries will want to go higher (6 to 10 kW).

What Should I Look For?

There are several things to watch out for when buying a home battery:

  • Capacity: Measured in kilowatt-hours (kWh), this tells you how much total energy the battery can hold.
  • Power output: Measured in kilowatts (kW), this shows how much energy the battery and inverter can deliver at any moment.
  • Depth of discharge: This is how much of the battery’s capacity you can safely use without damaging it.
  • Efficiency: This is the percentage of the power you put into the battery that you can actually use, because some energy is always lost in the storage process.
  • Warranty: This is a guarantee about the minimum performance you can expect before a battery degrades (they all degrade over time), and it’s often stated in years and charging cycles (whichever comes first). For example, EcoFlow promises at least 70 percent capacity after 15 years or 6,000 charging cycles.

How Much Home Battery Do You Need?

It can be tricky to calculate how much battery capacity you need, and it depends on your use case. If you want to guard against outages or live off-grid, you must consider how much power you use over time and also the sum of your maximum power usage at any given moment to ensure your capacity in kWh and output in kW are enough. If the output is not high enough you may not be able to run power-hungry appliances at the same time, so you’ll have to think about how you use your power.

For folks like me, simply looking to buy at a cheaper rate to use when power is more expensive, any capacity will benefit you. But if you have a cheap six-hour rate overnight, for example, then you ideally want it to last for the other 18 hours. It makes sense to get as much as you can up-front because the installation costs are high. Even adding to modular systems later often requires professional installation to avoid voiding your warranty.

Do You Need Upgrades or Permission?

The home battery will connect to your main electrical panel via a cable, and it may require some upgrades. There was no room on my fuse board when I got a home battery installed, so they had to install a second breaker box.

Some inverters may require permission from your electric distribution utility or local distribution company. Here in Scotland, the distribution network operator must approve your inverter, but you can install and then notify up to 3.6 kW, whereas larger inverters require prior approval.

If you want to guard against outages or live off-grid, you must consider how much power you use over time and also the sum of your maximum power usage at any given moment to ensure your capacity in kWh and output in kW are enough. If the output is not high enough you may not be able to run power-hungry appliances at the same time, so you’ll have to think about how you use your power.

For folks like me, simply looking to buy at a cheaper rate to use when power is more expensive, any capacity will benefit you. But if you have a cheap six-hour rate overnight, for example, then you ideally want it to last for the other 18 hours. It makes sense to get as much as you can up-front because the installation costs are high. Even adding to modular systems later often requires professional installation to avoid voiding your warranty.

Do You Need Upgrades or Permission?

The home battery will connect to your main electrical panel via a cable, and it may require some upgrades. There was no room on my fuse board when I got a home battery installed, so they had to install a second breaker box.

Some inverters may require permission from your electric distribution utility or local distribution company. Here in Scotland, the distribution network operator must approve your inverter, but you can install and then notify up to 3.6 kW, whereas larger inverters require prior approval.
