Dell Inspiron 13 7390 2-in-1 review: Considerable overhaul delivers a well-rounded convertible

Dell'south "Black Edition" Inspiron thirteen 7390 2-in-1 is a rather attractive convertible that gives fans of the XPS 13 two-in-1 a more affordable culling. Despite its more than amusing price, the 7390 holds onto plenty of premium features, including 4K bear upon display with precise color and active pen back up. I used it for about a week to see what information technology's all about and whether or not it's worth being your next device.

Dell Inspiron 13 7390 2-in-1 design and features

The Inspiron 13 7390 is built from a solid slice of stamped aluminum, finished with a black matte pigment that inspires the "Black Edition" branding. It does pick upward fingerprints and smudges, merely information technology'due south easy to wipe down. You don't get the same quality CNC machining as you find with the XPS lineup. But stamped aluminum isn't far behind when it comes to durability and precision. The Inspiron 7390 weighs more than the XPS 13 2-in-ane and is considerably thicker, but it's however a device that y'all'll hands be able to tuck nether an arm or into a bag.

The hinge is one of the most disquisitional parts of a convertible laptop. And Dell has made an innovative change that I don't doubt many other manufacturers will reproduce. All models send with an active pen for Windows Ink. And instead of having information technology magnetically attach to the side of the laptop (or not at all), it has a dedicated cutout on the inside of the hinge. It attaches magnetically to keep information technology in place, and it can be pulled out at any time in tablet, stand, or tent mode.

Now that it's been done information technology's hard to imagine why it wasn't done before. But it might have to do with the integrity of the hinge. Joints feel a bit flimsy, and at that place's a bit of a dead zone only past a ninety-degree bending where the lid tin can sort of float. The activeness is birthday smooth, and you won't have whatever bug converting to different modes, merely the hinge could no doubtfulness be better. It's the first rendition, so it's understandable it's not perfect.

The combination of 4K touch display, active pen, a comfortable keyboard, and strong performance brand this a versatile convertible that costs less than an XPS.

The Inspiron 13 holds onto a more varied port choice than the XPS 13 ii-in-1, offering HDMI and USB-C on the left side, as well as USB-A, 3.5mm audio, and microSD card reader on the right side. You lot can charge through the USB-C port, and the laptop ships with a barrel charging adapter. You tin can still connect to a USB-C docking station and easily handle video out, though lack of Thunderbolt 3 on a laptop this modernistic at this cost might be troublesome.

The laptop's ability button is thankfully not placed on the edge of the device where it can hands be hit in tablet mode. It's instead located in the height-right corner of the keyboard, and it's weighted differently to require a much harder press to activate. Even if you lot accidentally mash it while typing or rotating the display around, it shouldn't put your laptop to sleep. For some added security, a fingerprint reader is built-in for Windows Howdy. It'due south quick and accurate with no bug. At that place's no IR camera to a higher place the display, just the standard 720p camera will practice for video conferences and stills.

Audio is often not great on small Ultrabooks, though convertibles — which get in easier to consume media — should accept serviceable speakers. Unfortunately, the Inspiron 7390's sound is a miss. Speakers fizz even at low volume, and audio is thin. If you want to watch movies, Telly, or mind to music, you lot'll exercise best with a quality set of headphones.

Dell Inspiron xiii 7390 ii-in-i display and inking

Instead of the usual FHD and 4K display options offered by Dell, the Inspiron is just available with a xiii.3-inch 4K WVA touch display. It'southward bordered with sparse bezel along the sides and elevation, with a thicker mentum along the bottom. In tablet mode, there'due south enough to hold onto without accidental presses on the display, withal used as a notebook it gives off a premium air. A xvi:x aspect ratio would be more than than welcome for the actress screen real manor, specially in tablet manner. For now xvi:9 remains the standard.

Effulgence hits above 300 nits, but due to the glossy finish, the display is susceptible to glare in a well-lit room. It's not a deal-breaker, but you lot might find yourself maneuvering the laptop to notice a glare-gratuitous view on actress sunny days. Testing color accuracy, I got back 100% sRGB and 77% AdobeRGB, both excellent results.

The 4K resolution is brilliant, but at xiii inches information technology would exist squeamish to see an optional FHD model. Non simply would it exist less expensive and better for bombardment life, simply it also wouldn't make a huge deviation for well-nigh people who are going to use the laptop for productivity and occasional media consumption.

Pulling the N-Trig pen out of the unique storage delivers an average inking feel, with 1,024 levels of pressure sensitivity and no tilt support. It works great for jotting down notes or sketching out ideas, just don't look anything miraculous when used with advanced pattern or art apps. The pen includes two customizable buttons for shortcuts.

Dell Inspiron 13 7390 2-in-i keyboard and touchpad

The keyboard is black to match the rest of the laptop, with a three-stage white backlight for working in the dark. Keys are flat but smooth, and they all take equal and adequate travel. Typing for long periods is comfortable, and anyone who needs a device for pure productivity should be satisfied.

The Precision touchpad is sized appropriately for the rest of the laptop, and it's ringed in a silver bevel to better advertise its position. Information technology matches the colour of the keys, and there's a small line to announce left and right clicks. It's smooth, there'south room for Windows 10 gestures, and I had no issues during utilise.

Dell Inspiron 13 7390 two-in-1 performance and battery

With 8th Gen Intel "Whiskey Lake" Core i7-8565U CPU and 16GB of RAM, the Inspiron 7390 delivers functioning to hands cutting through general productivity tasks. There are only 2 configuration options, and you're limited to choosing between 256GB and 512GB SSD.

It would be nice to run into tenth Gen Intel hardware hither, especially for better-integrated graphics and Wi-Fi half-dozen support, though operation-wise the Whiskey Lake CPU isn't far behind. You'll have to bank check out Dell's XPS xiii 2-in-1 if you're assail a 10th Gen Intel CPU, though for a Core i7 you lot're looking at a considerably higher price.

The 52Wh bombardment would be much better suited to an FHD display, impact or not, since the 4K display here sucks upwards a considerable amount of power. I got between vi and seven hours of life from a charge when going about general piece of work — discussion processing, web browsing, video streaming — with a balanced power programme and effulgence at about halfway. That's not bad, but information technology'south not plenty to leave the AC adapter behind.

I ran some synthetic benchmarks to meet how well the Inspiron 13 7390 ii-in-1 holds up against other laptops we've recently reviewed.

The PCIe SSD certainly isn't every bit speedy as more premium laptops include, though you lot tin do an upgrade yourself after the purchase with a high-performance SSD.

Should you purchase Dell's Inspiron thirteen 7390 two-in-1?

If yous're in search of a meaty convertible laptop with balanced performance, colorful 4K display, and casual inking function, the Dell Inspiron xiii 7390 2-in-i is easy to recommend. The stamped aluminum chassis isn't quite every bit premium as the CNC machined chassis you lot'll get with the XPS lineup, but it'due south a close second. It'southward sleek, the black matte finish looks great, and the swivel, while a bit flimsy, doubles equally magnetic storage for the agile pen. It'south a smart design, and I don't doubt we'll showtime seeing information technology on more than laptops… as long as this one doesn't fall apart subsequently a few months.

I would like to see an FHD display option for better battery life — six to seven hours isn't enough to become through a workday — and a lower toll, but configurations are limited. Speakers are also disappointing, but that'south all yous'll have to put up within the confront of an otherwise first-charge per unit laptop.

The Inspiron 13 7390 tin human activity as a suitable media machine thank you to the 4K display — with a skillful set of headphones — nevertheless information technology can also act as an excellent productivity motorcar cheers to comfortable keyboard, sizeable Precision touchpad, and 8th Gen Intel Core i7 CPU, 16GB of RAM, and upgradeable K.ii SSD.
