Case
At 1.5 kg or 2.4 kg with the optional docking station, the tablet is heavier than its display size may suggest. The FZ-A3 is over 500 g lighter albeit without many of the expandable features of the FZ-G2. The chassis exhibits absolutely no warping or creaking when attempting to twist its corners.
The tablet itself integrates user-programmable buttons which can be incredibly useful depending on the application.
Connectivity
Port options are varied with two RJ-45 and both USB-A and USB-C. The dock itself adds additional USB ports, but it would have been great to see HDMI included as well.
The tablet cannot recharge via USB-C. Meanwhile, the USB-C port on the tablet supports DisplayPort-out while the USB-C port on the dock does not.
Communication
The unit comes with an Intel AX201 for modern Wi-Fi 6 and Bluetooth 5.1 connectivity. We experienced no issues when paired to our Netgear RAX200 test router.
Webcam
Maintenance
The back of the tablet includes four removable modules for the battery, storage, and two other accessories. The modules are not interchangeable meaning users must purchase their accessories from Panasonic carefully. The battery and storage modules are secured by latches while the other two will require a Philips screwdriver to install.
RAM is soldered and not user upgradeable.
Accessories and Warranty
Panasonic offers a wide variety of accessories that connect to the rear of the tablet or bottom edge such as the optional keyboard dock. Examples include include a barcode reader, SmartCard reader, LAN adapter, OPAL SSD, and more.
A three-year manufacturer warranty comes standard.
Input Devices
Keyboard
The keyboard is comfortable and even better than the keyboards on most consumer detachables in terms of tactility like the Microsoft Surface Pro or Dell Latitude 13 7320. Clearly, the heavier weight and thicker profile of the Panasonic dock help make the keys firmer and deeper for more satisfying feedback.
Touchpad
The small touchpad (7.9 x 4 cm) is smooth and compatible with gloves. Unfortunately, the cursor is jumpy even when gliding at constant speed with a bare finger. Regular cursor control is therefore more frustrating than it needs to be.
The dedicated buttons are very shallow in travel despite the thick base. Feedback is subsequently weak and unsatisfying.
Display
The displays on rugged tablets are traditionally high in brightness with poorer colors, grainier text, and lower native resolutions. The Toughbook FZ-G2 breaks this trend by integrating a glossy display that is closer to a consumer tablet in terms of visual quality without negatively impacting brightness or overall rigidity. Black-white and gray-gray response times are rather slow, however, meaning ghosting is noticeable.
Pulse-width modulation or screen flickering is present on brightness levels between 0 and 7 percent.

Color range encompasses only 79 percent of sRGB to be wider than the display on the Durabook S14I but narrower than most modern Ultrabooks where full sRGB is common.
Color temperature is slightly on the cool side. Once properly calibrated, both grayscale and color deltaE values would improve noticeably from 4.8 and 4.18 to 3 and 1.95, respectively.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 211.9 Hz | ≤ 7 % brightness setting |  |
The display backlight flickers at 211.9 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 7 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 211.9 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17909 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
Performance
Processor
Panasonic is sticking with Intel 10th gen Comet Lake-U vPro CPUs even though newer 11th gen Tiger Lake-U vPro options are already available. Processor performance is slightly slower than the average Core i5-10310U in our database due to the limited Turbo Boost potential of the Panasonic tablet. The newer Core i5-1135G7 is able to offer up to 30 percent faster performance in both single- and multi-threaded applications.
Upgrading to the Core i7-10810U SKU is expected to increase multi-thread CPU performance by about 50 percent over our Core i5-10310U configuration.

Emissions
System Noise
The tablet is generally quiet but never truly silent when in use. Watching YouTube videos, for example, would cause a constant fan noise of about 27 to 30 dB(A) against a silent background of 24 dB(A). Running higher loads like 3DMark 06 would boost fan noise to just over 35 dB(A). Expect the fan to pulse somewhat frequently especially when launching new applications.
Electronic noise or coil whine is noticeable only when placing an ear near the back of the tablet.

Temperature
Surface temperature hot spots are nearest the bottom right corner. Since the tablet itself is rather thick, the hot spots are generally small and not that warm. We're able to measure a maximum of just 38 C when running high processing loads for long periods.
(+) The maximum temperature on the upper side is 37.4 °C / 99 F, compared to the average of 34.2 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(+) The bottom heats up to a maximum of 36.6 °C / 98 F, compared to the average of 36.7 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 24 °C / 75 F, compared to the device average of 29.5 °C / 85 F.
(±) The palmrests and touchpad can get very hot to the touch with a maximum of 37.4 °C / 99.3 F.
(-) The average temperature of the palmrest area of similar devices was 27.7 °C / 81.9 F (-9.7 °C / -17.4 F).
Stress Test
When running Prime95 to stress the CPU, clock rates would boost to 3.3 GHz for about 10 seconds until core temperature reaches 100 C. Thereafter, clock rates would drop to 1.7 GHz for a cooler and more stable 61 C.
Running on battery power will not impact performance.

Speakers
The front-facing stereo speakers have poor bass reproduction as exemplified by the narrow pink noise graph below. Maximum volume is thankfully still loud and crisp to be sufficient for voice calls.

Power Consumption
The difference between minimum and maximum display brightness is about 5 W. Running higher loads will consume a few watts less than the Tiger Lake-powered Durabook S14I albeit with significantly slower graphics performance. Performance-per-watt is not as efficient and thus lower performance-per-watt on our Panasonic.
The small-medium AC adapter (~14.3 x 5.3 x 3.2 cm) is rated for a maximum output of 109.9 W.

Verdict
The Toughbook G2 is a great option for those who need a versatile Windows tablet and not just a slim one with very few connectivity features. The modular accessories and excellent display quality in particular are the most attractive selling points of the G2 as users can more easily adapt it for any given environment or function.
Perhaps the biggest drawback to the G2 is its heavy weight even after accounting for its rugged classification. The Durabook R11 offers both a larger display and upgradeable components while weighing several hundred grams lighter than the Panasonic. To make the clunkier Toughbook G2 more worthwhile, you'll have to exploit its versatile modules.
The Toughbook G2 is one of the most modular and customizable rugged tablets out there. You'll have to deal with its larger girth and heavier weight, however.
For future revisions, we would love to see larger latches and the elimination of pulse-width modulation for brightness control. The small latches securing the ports and modules are difficult to grip while users sensitive to onscreen flickering may want to avoid using the G2 at very low brightness levels. An internal update to Intel Tiger Lake would also provide a significant boost to graphics performance.
