The ISDT 608AC is a popular 6S ac/dc Li-Po charger. With AC input, it is limited to 60W, but in the field you can charge 200w with a xt60 power cable. It has several modes: Charging, Storage, Destroy, and DC Power Supply. Firmware updates are easily applied with the micro-usb port. I liked it enough to buy a second unit — and then things went wrong.
Charging mode has worked great as expected. I’ve been using it with a HGLC balance board for my larger batteries and a 1s series board for my whoop batteries.
But after flying my quads, I need to use the storage mode on each individual battery; that’s where the second unit came in. However, the discharge function on the 2nd unit stopped working in less than 6 months, so storage mode will work only on batteries under storage voltage. This also renders the destroy function inoperable for damaged packs.
The DC Power supply has been quite useful. I’ve used it with a low current limit to test powering up my quad after my questionable soldering repair. I’ve also used it to power a Matek ELRS Receiver to flash firmware before installation. It could even be used to power a TS100 soldering iron on the bench.
One other issue I’ve had is the first unit has a very noisy fan. I am fine ignoring it for now, and eventually I’ll swap the fan out myself. But when I tried contacting ISDT about the failed discharger, they didn’t even respond…
Overall Build Impressions The Dell Inspiron 14 Plus is very sleek and lightweight 14” laptop with a 16:10 screen and an aluminum case. Compared to my Dell Latitude E5470, it’s about .75” narrower, basically the same depth, and a bit slimmer. The Amazon listing says the color is “Atlantic Blue”, but the actual color is “Dark Green”. Either way, the color is very subtle and more of a dark grey-blue-green. As for the design, there are quite a few vents on this laptop with a large vented section on the underside, two rear-facing vents, and a large vent on each side. Port selection is somewhat limited with only 1 USB Type A on each side, a micro-SD slot and 3.5mm headset jack on the right, a full-size HDMI and a single USB C/Thunderbolt 4 port on the left. There is a barrel power connect on the left as well, but the laptop ships with a 90W USB Type C power brick, so unless you have a power brick from another Dell, you are limited to the Thunderbolt 4 port for power.

Screen The screen is a 14” 16:10 2240×1400 display in a matte variety, or as Dell calls it, ComfortView Plus. There is some bleed toward the upper edge when viewing a black screen with the brightness all the way up, but when viewing any content, the black level, contrast, and colors seem quite good. There is display scaling set to help with normal viewing as the screen is 188PPI and native without scaling makes everything a bit too small for me. Not all applications look the best with scaling applied, so you may run into some situations where text looks a bit fuzzy or menu/window sizing is a little off.

Temperatures The Inspiron 14 Plus comes with a dual-fan setup with large intake vents and several exhaust vents. Temperatures are kept under control mainly with a 45W PL1 setting. While plugged in (not on battery), CPU Package Power hits 80W under load during PL2, at which point Package temperatures hit 95C. After Tau time runs out and it drops to the 45W PL1, temperatures drop down to 76C under load. The bottom of the laptop stays relatively ok, though the section to the rear does get quite warm to the touch. The keyboard deck is never too warm (a problem with my Precision 7560). If you are doing anything intensive, make sure you have the intake/exhaust clear and place on a hard surface, ideally on a desktop and not a lap. The fan noise is kept to a minimum and is not a distraction during most all usage.

Power Consumption/Battery Life Using my Kill-A-Watt, I measured the idle power consumption at the wall at 8.5W. The draw on load during the 3DMark TimeSpy benchmark was measured at a max of 93W during the CPU test for a few seconds before dropping down to a fairly steady 49W-52W for the majority of the test. The power brick got warm to the touch, but never excessive or uncomfortable.
Internals Looking at the internals of this laptop, you can see the only three upgradeable parts. The SSD is a 2230 format WD SN740 1TB PCIe 4.0 NVME drive with a small copper heat spreader attached. There is only one DDR5 SODIMM slot available to upgrade the memory, as 8GB is onboard. The slot is filled with a Samsung DDR5 4800 stick from the factory. Wi-Fi is handled by an Intel AX211NGW card.

Keyboard/Touchpad There is quite a bit of flex in the keyboard deck when pressing down compared to my Dell Precision 7730 and Precision 7560, though it’s plenty usable. Compared to some cheaper Dell Inspiron laptops I’ve used in the past (3000 series from 5 or 6 years ago), it’s much improved, though their business laptops are nicer to type on with better feel and feedback. I’m used to mechanical keyboards with an EVGA Z15 as my daily keyboard, so most laptop keyboards are a compromise to me anyway. The keyboard is backlit which makes it much nicer to use in dim lighting. The power button in the top right corner doubles as a fingerprint reader, though I have not set up Windows Hello to try that out. The touchpad is quite large and is a Precision Touchpad with gesture capability. The surface is low friction and tracking is very good. I have had some issues with taps not registering, though, and the click point for the right/left click is not very well defined. This is pretty standard for clickpads like this, though, and this laptop is better than most with a firm, quiet click and no rattle or bounce. I prefer my Latitude and Precisions with separate left/middle/right mouse buttons below the trackpad and wish Dell would bring this back to the Inspiron line.
Webcam/Speakers This laptop does have a physical shutter on the webcam for privacy, which is nice to see making its way onto the Inspiron lineup. Dell finally introduced a 1080p webcam to the Inspiron making a nice upgrade from the standard 720p that has been used for many years. The sharpness still isn’t quite up there with a standalone 1080p webcam, but lighting is handled well and the two microphones do a good job of picking up clear audio. The Inspiron 14 Plus has two down-firing speakers toward the front and give a very filling sound, with the exception of not much bass at all. Highs are very clear and mids are present with no distortion noticed.

Network Transfer Speed The Inspiron 14 Plus comes with an Intel AX211NGW tri-band Wi-Fi card. I connected to my AX router and was able to sustain 60MB/s transfer from my NAS to the laptop from approximately 10ft distance through one wall.
Final Comments This is a very nice laptop and seems like a very solid choice, with a few personal quibbles. I think the chassis would be a little better suited to something like the i7-1260P (28W, TDP Up of 64W) where it could run in the higher performance TDP setting longer. Putting an H-series 45W, even with the TDP Up limited to 80W, it drops down the 45W very quickly and performance does suffer. The i7-12700H can be configured up to a max TDP Up of 115W, which is way more than this chassis can handle, so there is some performance left on the table with this processor that other laptops are able to make more use of. That said, as a whole, this laptop is very nice and would be a great choice for someone needing a powerful, compact laptop with an excellent screen. Amazon had this laptop for $1105 during Prime Day 2022, and that seems like a fair price to me. Dell currently lists this laptop for $1399 direct and at that price, I would probably be looking at other options (Latitude 5420/5430 for example).
