For anyone drawing regularly, the Huion H610 Pro beats the Huion H420 on working area, pen generation and shortcut count. The H420 earns its place only when a surface of 106 × 64.6 mm is the point, which is why it survives as a signature pad, an osu! tablet and a compact mouse replacement. Both are legacy screenless hardware, and the Huion brand guide covers the current models that replaced them.
Neither is a sensible default purchase today. They are sold as residual or second-hand stock while their direct successors, the H420X and the H610X, carry current platform support, USB-C and battery-free pens.
The complication is that "H610 Pro" is not one tablet. Huion shipped at least three generations under that name, and they do not share a stylus. Before comparing anything else, the practical question is which generation is in the box and whether the pen that ships with it can still be replaced.
Which Versions Are We Comparing?
The H420 has one hardware design, and Huion publishes a single specification for it: a 106 × 64.6 mm working area, a 7.5 mm chassis, 167 g weight, the PEN68 stylus and a Mini USB port. The black and the white versions are colour SKUs of that same tablet. A listing that describes an H420 White changes nothing except the shell colour. The H420X is a different product rather than a revision, and it appears later in this comparison.
"H610 Pro" is where the confusion starts. Huion's own support documentation separates the generations by pen: the V2 takes the battery-free PW100, while the earlier versions take the rechargeable PEN80.
| Generation | Pen | Pressure levels | Tilt | Order |
|---|---|---|---|---|
| H610PRO (original) | Rechargeable PEN80 | 2,048 | None | Oldest |
| H610PRO (8192) | Rechargeable PEN80 | 8,192 | Not documented | Middle |
| H610PRO V2 | Battery-free PW100 | 8,192 | ±60° | Newest |
All three keep the same working area, the same 10 mm chassis and the same 8 physical keys plus 16 soft keys, so the pen is the fastest way to tell them apart.
Marketplace listings make this worse rather than better. A listing that has carried the H610 Pro name since the original generation now presents itself as the H610PRO V2, which means the page title, the date-first-available field and the review history behind it say nothing about the hardware that will arrive. Two checks survive listing changes: a rechargeable PEN80 means a pre-V2 tablet (the 2,048 or 8,192 pressure rating on the box separates those two), and a battery-free PW100 with ±60° tilt means the V2.
Working Area: 4-Inch Class vs 10 × 6.25 Inches
The H420 maps 106 × 64.6 mm of surface to your monitor, marketed by Huion as 4 × 2.23 in, a figure that does not convert cleanly from the metric dimensions. The H610 Pro maps 254 × 158.8 mm, marketed as 10 × 6.25 in. The larger surface is roughly 5.9 times the area of the smaller one, and that ratio drives almost everything else.
Both tablets use absolute mapping, where a point on the tablet corresponds to a point on the screen. Compressing a large monitor onto a 4-inch surface means a few centimetres of hand movement cross the entire canvas, which magnifies every tremor and makes slow, controlled line work harder. That makes slow, controlled line work harder and forces frequent repositioning during long strokes, because the stroke runs out of surface before it runs out of canvas.
The compact surface is a design choice with a genuine use case rather than a defect. The H420 suits signature capture, osu!, mouse replacement on a cramped desk and travel, all of which reward a small footprint. Neither tablet has a display, so screen size never enters this comparison. The only measurement that matters is the active drawing surface.

Pen and Pressure: PEN68, PEN80 and PW100
The H420 uses the PEN68, an electromagnetic pen powered by a single AAA battery. It reports 2,048 pressure levels at 4,000 LPI and 200 PPS, carries two side buttons and lists no tilt support. Battery power is not the only part that ages, and replacing the pen does not reset the rest of the hardware.
Both pre-V2 H610 Pro generations use the rechargeable PEN80, which Huion's store lists for the H610 (2048), H610Pro (2048) and H610Pro (8192), with battery life quoted at roughly 350 hours per charge. The original is specified at 2,048 levels, 5,080 LPI and 233 PPS with no tilt, and the 8,192-level generation raises the pressure rating on the same chassis.
The V2 is the version worth targeting. It replaces the rechargeable stylus with the battery-free PW100, holds 8,192 pressure levels at 5,080 LPI and 233 PPS, and supports ±60° tilt.
It is tempting to read 2,048 against 8,192 as the headline. It is not. Pressure resolution matters at the margins, but the change that alters daily use is the pen's power source: a rechargeable stylus inside a discontinued tablet means a battery that will eventually stop holding a charge, and replacement stock for the legacy pens is not guaranteed. The PW100 removes that problem entirely.

Controls: 3 Express Keys vs 8 Keys and 16 Soft Keys
The H420 offers three programmable physical keys and two pen side buttons. That is the whole shortcut surface, so most commands stay on the keyboard.
The H610 Pro family offers eight programmable physical keys, sixteen soft keys and two pen buttons. The soft keys are the most misreported specification here: they are flat zones tapped with the pen rather than sixteen additional mechanical switches.
The practical difference is workflow rather than specification. Eight physical keys plus sixteen pen-tapped zones keep brush size, undo, layer and zoom off the keyboard. On the H420, a keyboard stays beside the tablet for anything beyond the three programmable keys.
Drivers and Platform Support Today
Baseline compatibility and actual support are different things on hardware this old.
The H420 is specified for Windows 7 or later and macOS 10.8 or later, and Huion's page lists no other platforms. Its drivers are the legacy V12 packages, so the tablet depends on an older driver line than the current range.
The H610 Pro generations are in better shape. The H610 Pro V2 is listed for Windows 7 or later, macOS 10.12 or later and Android 6 or later, and Huion's Linux support centres on Ubuntu, so check the exact model against Huion's driver page before relying on it. The earlier H610 Pro generations are not on Huion's current product pages.
All the tablets in this comparison are wired Mini USB with no wireless or Bluetooth option. On hardware this old, a tablet that appears disconnected, loses pressure or registers the pen intermittently is worth treating as a driver or cable problem first, and reinstalling or changing the driver version should be tried before a used unit is written off as faulty. The drawing tablet setup guide walks through the install order that avoids most of it.

Nibs, Pens and Accessories
A legacy tablet lives or dies on part availability, and nib compatibility follows the pen rather than the tablet. PN01 nibs fit the PEN68 and the PEN80 family, which covers the H420 and both pre-V2 H610 Pro generations. PN04 nibs are the correct pack for the PW100, which means the H610PRO V2. Matching by tablet name alone is how the wrong nib ends up in a pen.

The H610 Pro V2 manual lists spare nibs in the box, so check there before buying a pack. On the pen side, the PEN68 is still sold directly by Huion, the PEN80 remains the documented replacement for the pre-V2 models, and the PW100 is the current V2 pairing.

A drawing glove is a defensible purchase on the H610 Pro's larger surface, where a resting hand sits on the tablet for longer stretches, and optional on the H420.

Two accessory categories matter less than they seem. These are screenless surfaces designed to work flat, so a generic stand that flexes under pen pressure is worse than no stand. Third-party films for both exist, but adding one changes surface friction and accelerates nib wear, which makes it a preference rather than a fix.
The Modern Lineage: H420X and H610X
Both entry-level families have current replacements, and they solve most of what ages badly in the originals. The H420X keeps the ultra-compact concept at roughly 106 × 66 mm, switches to USB-C, and pairs a battery-free PW100 with 8,192 pressure levels, 5,080 LPI and a faster report rate in a lighter chassis with Windows, macOS, ChromeOS, Android and Linux support.
The H610X keeps the 254 × 158.8 mm working area, the PW100 pen, 8,192 pressure levels and ±60° tilt, and moves to a 324.5 × 205.6 × 8 mm chassis weighing 515 g with USB-C and current platform support.
That produces a simple buying rule. A legacy H420 or H610 Pro makes sense when it is already on your desk, when it turns up unusually cheap second-hand, or when a specific legacy setup requires it. It does not make sense simply because the listing is still live, which is the trap the complete buying guide is built to avoid.
Which Entry Huion Is Right for You?
- Already own one: keep it. Replace the nibs, and the pen if its battery or side button has failed, but neither tablet is worth repurchasing new.
- Want the bigger drawing surface: the H610 Pro V2 is the only generation whose pen is still a current product. Confirm the PW100 and ±60° tilt before paying.
- Only a pre-V2 unit is available: the 8,192-level model with the rechargeable PEN80 works, but budget for a replacement pen. The original 2,048-level tablet has no tilt at all and no reliably identifiable new listing.

- Need a genuinely tiny tablet: the H420, or the H420X if you want a current one. On a cramped desk, or for signatures, osu! and mouse replacement, the small area is the feature rather than the compromise.
- Buying a first tablet to draw on: neither. A current budget model brings modern drivers, USB-C, a battery-free pen and spare parts that will still exist in three years. The budget drawing tablet roundup and the beginner picks both start at that level, and the teens and students list covers the same ground for a tighter budget.
Conclusion
The H610 Pro is the better drawing tool of the two, and it is not close: a working area nearly six times larger, eight physical keys instead of three, and a pen generation that, in V2 form, removes battery charging from the equation. The H420 remains a competent compact tablet for signatures, rhythm games and mouse replacement, where its size is an advantage rather than a limitation.
The verdict on buying either one is more cautious. Both families are legacy hardware with legacy driver dependencies, and only the H610PRO V2 combines a battery-free pen, ±60° tilt, Android 6+ support and a replacement stylus that is still in production. If you find a pre-V2 model at a genuinely low price, treat the pen as a consumable and factor its replacement into what you pay.
Before any of that, identify what you are looking at. Check the pen model, the pressure specification and the tilt range, in that order, because those three details survive the listing merges that have confused buyers of this family for years. Whichever way you go, the Huion tablet range and the beginner drawing tablet guide show what a current entry-level purchase looks like today, and whether a drawing tablet is worth it is the honest starting question if you are still deciding whether you need one at all.
