Fanttik E2 vs S2: E2 Ultra or S2 Pro Screwdriver?

Short answer: buy the Fanttik E2 Ultra if you open phones, laptops, small appliances and RC cars — its torque starts at 0.05 N.m. Buy the Fanttik S2 Pro if you assemble furniture and cabinets — its range picks up around where the E2 Ultra tops out and climbs to 8 N.m. They are not upgrades of each other.

Quick Answer: E2 Ultra vs S2 Pro at a glance

This is the single most useful thing to understand before you compare anything else: the two tools barely share a torque range. The E2 Ultra's highest setting (0.6 N.m) sits just above the S2 Pro's lowest setting (0.5 N.m). Everything else in the spec sheet follows from that one design decision.

The differences that actually matter

1. Torque range: two different jobs, not two price tiers

The E2 Ultra offers five torque gears: 0.05, 0.1, 0.2, 0.4 and 0.6 N.m. That entire range lives below 1 N.m, which is the territory of Phillips 000 screws in a phone midframe, laptop bottom covers, camera bodies and RC chassis plates. A 0.05 N.m first gear exists so you can seat those screws without putting a soft brass insert or a plastic boss under more force than it can take.

The S2 Pro's torque settings are published as 0.5/1/2/3/4/5/6/8 N.m — an order of magnitude higher at the top. That is what a cam-lock fitting, a cabinet screw or a bed-frame bolt actually needs. Ask the E2 Ultra to do that job and it simply will not drive the fastener home; ask the S2 Pro to close a laptop and its lowest gear (0.5 N.m) is already ten times the E2 Ultra's finest 0.05 N.m setting.

This is why "which is better" is the wrong question. The right question is what size of screw is in front of you.

2. Battery: 800 mAh versus 2000 mAh

The S2 Pro carries a 2000 mAh cell — 2.5x the E2 Ultra's 800 mAh — and its spec sheet notes 5V/1A charging. That gap matches the workload: a furniture build is a long run of high-torque screws in one sitting rather than a few tiny ones. The E2 Ultra's smaller pack is part of what keeps it slim enough to hold like a pen over a workbench.

3. Bit count and what comes in the box

The E2 Ultra ships with 50 S2 magnetic bits; the S2 Pro ships with 20. Again this tracks the use case — a single electronics teardown can throw several different screw-head types at you, while furniture assembly is a handful of sizes repeated a hundred times.

The E2 Ultra's kit is also listed with a pry bar and tweezers, the two things you always need when a battery is glued down. The S2 Pro instead includes a 90° angle adapter and an extended rod — accessories that only make sense when you are reaching into the back corner of a wardrobe you have already half-built.

4. Speed and handling

Free speed is close: 270 RPM on the E2 Ultra, 250 RPM on the S2 Pro. Neither is a drill, and that is deliberate — precision fastening is about controlled seating, not fast spinning. The 20 RPM gap is not a buying reason either way. Note that the S2 Pro's spec sheet lists Pivotable as ✘, so if you specifically want an articulating body, neither of these two is that tool.

5. Storage and price

The E2 Ultra uses a rotatable magnetic case; the S2 Pro uses a premium magnetic storage box. Both are magnetic-retention designs, which matters more than it sounds — a case that holds bits when tipped is the difference between a tidy bench and a micro bit lost under the workbench. As of writing the E2 Ultra is $69.99 and the S2 Pro is $79.99, a $10 spread that is far smaller than the capability gap between them. The E2 Ultra is listed in Gray, Red and White at the same price; the S2 Pro is offered in a single configuration.

Which One Should You Buy?

Buy the E2 Ultra if: you repair phones, tablets, laptops, cameras, small appliances or RC cars. You need sub-1 N.m control, a wide bit library and pry/tweezer tools in the same case. Its listed use cases are small appliances, PC and RC car work.

Buy the S2 Pro if: your weekend is flat-pack furniture, shelving, cabinet hardware or mounting brackets. You need real driving torque up to 8 N.m, a bigger battery for long sessions, and the angle adapter and extension rod for awkward reaches. Its listed use cases are furniture install and PC repair.

Buy both if: you do genuinely both. There is no meaningful overlap to exploit — the only overlap is the sliver between the S2 Pro's 0.5 N.m floor and the E2 Ultra's 0.6 N.m ceiling, so one cannot substitute for the other. At $69.99 and $79.99 as of writing, owning the pair is the honest answer for a mixed workshop.

FAQ

What is the difference between the Fanttik E2 and S2?

They are different product lines, not generations. The E2 Ultra is a precision driver with 5 torque gears from 0.05 to 0.6 N.m for electronics. The S2 Pro is a cordless driver with torque settings running 0.5 to 8 N.m for furniture and general assembly.

Is the S2 Pro just a more powerful E2 Ultra?

No. More torque is only half of it. The S2 Pro also carries a 2000 mAh battery versus 800 mAh, ships 20 bits versus 50, and swaps the pry bar and tweezers for a 90° angle adapter and extended rod. It is built around a different job.

Can the E2 Ultra assemble flat-pack furniture?

Its top gear is 0.6 N.m — barely past the S2 Pro's 0.5 N.m entry setting, and more than ten times below the S2 Pro's 8 N.m top setting. Fanttik lists the E2 Ultra for small appliances, PC and RC car work, and the S2 Pro for furniture install. For cabinet and bed-frame screws the S2 Pro is the correct tool.

Do the E2 Ultra and S2 Pro use the same bits?

Both kits are specified as S2 steel magnetic bits (50 and 20 pieces respectively), but the official spec sheets do not publish shank dimensions for either tool. Check the shank size in each product's manual before buying replacement or third-party bits.
