Ryobi sells the drill, the batteries and the charger, then leaves the storage and carrying to you. Third-party makers fill that gap with the unglamorous end of the ONE+ system: a rack that gets loose 18V packs onto the wall, a hard case shaped around the drill, and belt clips for the tools you keep setting down. None of the three costs twenty dollars, and each one fixes a daily annoyance instead of adding a feature.
LIZEWEI battery racks, for packs that live on the bench
The LIZEWEI set is two bent-metal racks painted the same lime green as the tools. Each rack runs 12.4 inches with three slots, so the pair puts six 18V packs in a row on the wall, and the screws and drywall anchors for mounting are in the box.

Hang them on the wall, under a shelf or on the bench itself. The packs hang by their stems in a line you can read at a glance, which means the charged ones and the flat ones can finally keep separate rows.
At 4.8 stars across 201 ratings, it is the best-reviewed piece of bent metal in this roundup.

Tourmate hard case, shaped for the ONE+ drill
The Tourmate case is a hard EVA shell cut for one tool, Ryobi’s ONE+ 18V 1/2-inch drill/driver, the PCL206B.
It measures 9.4 by 8.4 by 4.7 inches outside and weighs 1.2 pounds, the lid carries a zippered mesh pocket for bits and small parts, and the inside is lined rather than bare plastic.

The price does not include the drill, the battery or the charger; it is case only. What $19.99 buys is a rigid shell between the drill and everything it would rattle against in a tool bag or a truck bed, and buyers rate it 4.5 stars across 43 ratings.

Ullnosoo belt clips, a hook on every tool
Ryobi’s clip design carries its own part numbers, 633586002 and 636181001, and Ullnosoo bends its replacements from 304 stainless steel to match.
Five clips and the screws to mount them cost $6.99, they fit Ryobi and Ridgid 18V tools, and they hang a tool from a belt, a table edge, a shelf or a rack.

The hook changes the small math of a job: the drill stops landing on the floor or the bench edge between holes, and it is still on your hip when you climb down.
The 10-pack runs $8.99 when the whole fleet needs hooks, and the listing holds 4.4 stars across 365 ratings. Cheapest fix in this piece, and the one you feel first.
Price: $6.99 for the 5-pack, $8.99 for the 10-pack

Which one first
All three together come to $40.87. Buy the rack if your batteries live on the bench, the case if the drill rides in a bag, and the clips either way, because a hook on the drill pays for itself the first day it stays on your hip instead of the floor.
