Snapshot

The 30-Second Version

A budget 2-in-1 that nails the basics with 16GB of RAM and a Ryzen 5, but the tiny 256GB SSD and mediocre screen hold it back. Buy it for the flexibility, not the performance.

Pros & Cons

Pros

  • 16GB of RAM is generous for this price point 82nd
  • Lightweight 2-in-1 design with a 360-degree hinge 72nd
  • Digital pen included in the box
  • Ryzen 5 4500U handles multitasking well

Cons

  • 256GB SSD is cramped for 2024
  • Screen quality is below average for the category
  • Port selection is limited, only one USB-C
  • Wi-Fi 5 instead of Wi-Fi 6

What owners think

The Word on the Street

4.8/5 (4 reviews)
👍 Owners like the lightweight design and the fact that the pen is included, not an upsell.
🤔 A few buyers mention the screen could be brighter and more color-accurate.
👎 The 256GB SSD is a common gripe, with people wishing Lenovo had offered more storage.

The proof

Performance

The Ryzen 5 4500U is a workhorse for everyday tasks. Six cores and 16GB of DDR4 means you can have 30 Chrome tabs open, Spotify running, and a Zoom call going without the thing grinding to a halt. The integrated Radeon graphics sit at the 70th percentile in our database, which is fine for light photo editing and older games, but don't expect to run Cyberpunk on this. The 256GB SSD is the real bottleneck here. That's the 16th percentile for storage, and it fills up fast if you're installing anything beyond the basics.

vs Competition

Stacked against the Microsoft Surface Laptop 7th Edition, the Flex 5 loses on build quality and screen, but wins on price and RAM. The Surface is a premium machine with a gorgeous display, but you'll pay a lot more for similar specs. The ASUS ROG Zephyrus G14 is in a completely different league for gaming and performance, but it's also heavier and way more expensive. If you're comparing to the HP OMEN Transcend 14, that's a gaming-focused machine with a much better GPU, but again, you're paying for it. The Flex 5 is the budget-friendly everyday option in this crowd.

Price

Value & Pricing

At $900 USD, this is a fair deal but not a steal. You're paying for the 2-in-1 flexibility and the included pen. If you don't need the touchscreen or tablet mode, you can get a traditional laptop with better specs for the same money. But if you want a convertible that won't feel sluggish, this is a reasonable choice.

Overview

The Lenovo Flex 5 81X20005US is a budget 2-in-1 that gets the basics right. You get a Ryzen 5 4500U, 16GB of RAM, and a 14-inch FHD touchscreen in a 3.64 lb chassis that won't wreck your shoulder. It's not going to blow anyone away, but for around $900 USD it's a solid everyday machine that doubles as a tablet when you need it. The included digital pen is a nice touch that most competitors charge extra for.

Common Questions

Q: Does this come with the Active Pen 2?

Yes, a digital pen is included in the box. No need to buy one separately, which is a nice bonus at this price.

Q: Can this handle gaming?

Light gaming, sure. The integrated Radeon graphics can handle older titles and indie games at lower settings. But this is not a gaming laptop. If you want to play modern AAA games, look at something with a dedicated GPU like the ASUS ROG Zephyrus G14.

Q: Is the battery life actually 10 hours?

Lenovo claims up to 10 hours, but real-world usage usually lands closer to 6-7 hours with mixed use. The quick charge feature is handy though, getting you to 80% in about an hour.

Who Should Skip This

If you need serious storage, a high-quality display, or gaming performance, this isn't it. Go get a traditional laptop with a 512GB or 1TB SSD and a better screen instead. And if you're a creative professional who needs color accuracy, the Microsoft Surface Laptop 7th Edition is worth the extra cash.

Verdict

The Lenovo Flex 5 81X20005US is a solid budget 2-in-1 for students, casual users, and anyone who wants a laptop that can occasionally pretend to be a tablet. The 16GB of RAM and Ryzen 5 4500U are a good combo for multitasking, and the included pen sweetens the deal. Just know that the 256GB SSD is going to feel tight, and the screen won't win any awards. If you can live with those compromises, it's a decent buy.
