- Is the Ryobi glue pen worth it?
- For small crafts and quick repairs, yes. At $29.97 at The Home Depot as of November 5, 2026, it is cheap, and it reuses Ryobi USB Lithium batteries. Skip it if you need high heat or long glue beads.
- What glue sticks does it use?
- It takes 0.3125 in (5/16 in) diameter glue sticks. That is smaller than the 7/16 in sticks most full-size glue guns use, so stock the right size.
- How long does it take to heat up?
- Ryobi rates it at under 30 seconds, and the LED indicator shows when it is ready. That is much faster than typical corded glue guns.
- Can I use my other Ryobi USB Lithium batteries?
- Yes. It runs on the Ryobi USB Lithium battery system, so batteries from other tools in that line work in it.
- Does it have temperature control?
- No. It runs at a fixed 347°F with no dial, so it is not the tool for heat-sensitive materials or high-temp glue.
- What comes in the kit?
- The box has the USB Lithium glue pen and a Ryobi USB Lithium battery. Check whether a charger is included before buying if you have no other USB Lithium tools.
