GSR18V-400B22 vs PBLDD02K1: compact two-battery kit or 4Ah kit option
Compare a compact Bosch kit with two 2 Ah packs against the full-size RYOBI 4Ah kit option, keeping unverified package details visible.
The decision in brief
How the options differ
The Bosch GSR18V-400B22 is a compact 6.3 in head-length drill with two BAT612 2 Ah batteries and a bag. The RYOBI PBLDD02K1 is a full-size HP brushless drill whose kit option is labeled 4Ah Battery/Charger. Both state torque as up to figures without a basis, and RYOBI's package tabs did not render, so several details remain open.

The buying guide
Package and specification details
Compare the stated figures on their own terms
Bosch states up to 400 in-lbs max torque with 0-500 and 0-1,900 RPM no-load speeds and 20 clutch settings. RYOBI states up to 850 in-lbs with 0-700 and 0-2,150 RPM and a 24-position clutch. Neither page gives a test basis, so the two torque numbers are manufacturer statements, not a measured comparison.
The Bosch page and the seller list two BAT612 2 Ah batteries, an unnamed 18V charger, a belt clip and a carrying bag; the Bosch includes list also prints two drill/driver lines for a one-drill kit. RYOBI's kit option names a 4Ah battery and charger, but the Includes tab did not render, so battery model, count and bag are unverified.
Bosch states a 6.3 in head length and 1.95 lb without saying whether a battery is included. RYOBI's page states no weight or length. A compact head length is a stated dimension, not a guarantee of access to a specific cavity.
Is PBLDD02K1 the official replacement for PBLDD01K?
RYOBI marks PBLDD01K as Discontinued but names no successor. PBLDD02K1 is the current HP brushless 1/2-in drill/driver kit listing with different stated torque, speeds and battery; it is recorded as the current product, not as a declared replacement.
These manufacturer specifications do not establish measured performance, noise, long-term reliability or running cost. We have not independently tested these products. Check current prices, stock and operating-space instructions with the seller and manufacturer.

Bosch's includes list prints two GSR18V-400 drill/driver lines; the kit name and the seller list describe one drill. Confirm with the seller before purchase.
The charger model is not named by Bosch or the seller. GSR18V-400B12 is a one-battery kit of the same drill.

Brushless motor
Whether the manufacturer documents a brushless motor.
Brushless describes the motor design. It is not a power, runtime or service-life measurement.
The published torque or power figure with its unit and any stated basis, kept as text.
In-lb, Nm and UWO figures are not converted or compared across bases here. A relative claim against another model is recorded as no figure.

Maximum no-load speed
The top of the highest published speed range.
No-load speed falls under load and is not a drilling-rate or power measurement. Check the low range for driving large fasteners.

Mechanical speed ranges
The number of published gearbox speed ranges.
A two-range gearbox and a variable-speed trigger are different controls. The count does not describe the width of each range.

Whether a hammer-drilling mode is documented for this exact model.
Hammer drill/drivers are different models with their own SKUs. False means the retrieved pages present the tool as a drill/driver with no hammer function.

Stated tool weight
The published weight, with the battery condition kept in the note.
Makers quote weight with or without a battery and rarely say which pack. Read the note before comparing two figures.

The published front-to-back length, with its measurement basis kept in the note.
Some makers quote head length only and others overall length. A smaller number does not establish access to a particular cavity.

Bag or case in this package
Whether the selected US package explicitly lists a carrying bag or hard case.
Bag and hard case are different items. Unknown means the retrieved package list did not mention either.
GSR18V-400B22 kit with two BAT612 2Ah batteries (US)
Bosch's weight line does not say whether it includes a BAT612 battery, so it is not directly comparable with figures quoted with a pack.
Bosch's includes list prints two drill/driver lines for a kit that the name and seller describe as one drill; treat it as a page artifact to confirm before purchase.

RYOBI's Includes and Specifications tabs did not render, so weight, length and the exact battery model and count are unverified.
The earlier PBLDD01K kit is marked Discontinued by RYOBI; RYOBI names no successor, so PBLDD02K1 is recorded as the current listing rather than a declared replacement.
