7mm glue gun buying guide

Updated: 23 October 2026

You are looking at a mini glue-gun kit on amazon.co.uk and the title, the bullets and the technical details do not agree. A 7mm glue gun buying guide is the order to read those lines in, before the stick count does the deciding. On 19 October 2026 the seven kits in our [hot glue gun 7 mm comparison](/hub/fillers-adhesives-and-sprays/hot-glue-gun-7mm) sat between £7.39 and £10.99 for the corded guns, and £14.99 for the cordless gun. This page is the checklist, not a winner. We compared the listings and public UK safety notes, and we did not run a lab test. A qualifying purchase through our links can earn a commission at no extra cost to you.

Confirm it is a 7 mm gun

Start with diameter. Mini is only a word, and length is a different number. Every gun in this set is sold as a 7 mm tool: sticks of 7 × 100 mm, 7 × 130 mm, or, on the cordless Tilswall W106s, 0.275 in × 5.51 in, about 7 mm by 140 mm. A shorter stick fits the same gun and you reload more often. DEKO and ValueMax ship 100 mm sticks. MAXDONE, Tilswall W101 and Assark ship 130 mm. RUNSAI lists 30 sticks of 7 mm and does not give the length. Diameter is not temperature. Dremel’s UK manual pairs its 7 mm guns with 165°C and its 11/12 mm gun with 195°C on high. That is one brand, not a rule. If the drawer holds thicker sticks, read the 7 mm versus 11 mm glue gun page.

Check the plug and the voltage line

UK mains are 230 V, and a glue gun for a UK socket wants a UK 3-pin plug. Electrical Safety First says to use that plug, not a travel adaptor, and to rest the gun on a non-flammable surface. RUNSAI prints 230 V, with a 1.5 m cable. MAXDONE prints 220 V. Tilswall W101’s technical details print 120 V, and the raw text does not confirm a BS 1363 plug. Assark, DEKO and ValueMax do not print a voltage, so that field is n/a until the live page shows one. The 120 V line is not a reason to buy a travel adaptor. Before you rely on W101, look at the plug photos on the live amazon.co.uk page.

Match watts to the job, not to a league table

Wattage here is a listing class, not a measured output. The corded guns are sold as 20 W (DEKO and ValueMax), 30 W (RUNSAI) or 50 W (MAXDONE and Tilswall W101). The cordless W106s is listed at 15 W. A higher watt figure is not a temperature. Only W101 (165°C) and W106s (170°C plus or minus 10°C) state one. Everywhere else the temperature is n/a, which is not cool-melt. Assark’s title and bullets say 50 W, the technical details say 40 W, and one review says 20 W. MAXDONE’s listing says 50 W and one review says 25 W. Use the listing figure, and notice the disagreement. Heat-sensitive materials are on the hot glue gun for crafts page.

Sticks, stand and switch

Stick counts run from 20 (ValueMax and the cordless W106s) through 30 (MAXDONE, RUNSAI, DEKO) and 60 (Assark’s bullets) to 75 (W101). More sticks do not repair a voltage line you have not checked. Assark’s included-components field names the gun, while the bullets say 60 sticks. A stand is claimed on the corded kits and is not settled in the reviews. MAXDONE’s wire rest is flimsy unless you arrange the flex. One DEKO delivery arrived without the pictured rest. ValueMax’s bracket is described as too light. W101’s folding stand is stable for some people and tips for others. An on/off switch is printed for MAXDONE, with an LED, and for W101 and Assark. RUNSAI, DEKO and ValueMax do not show one in the spec block. If the title and the technical details disagree, trust neither number until they match.

Common questions

What should I check before I buy a 7 mm glue gun?
Read diameter first, then the plug and the printed voltage, then watts, and only then the stick count, the stand and the switch. The awkward lines are Tilswall W101’s 120 V technical details and Assark’s 40 W and 50 W on the same page. A star rating does not settle either of those.
Is 20 W enough, or do I need 50 W?
For a short card, a small repair or a few fabric dots, a listed 20 W gun such as DEKO or ValueMax is the class these pages are selling. A listed 30 W or 50 W gun is the class for a longer bench session. We have not measured the output. Watts are not a temperature.
Why do two numbers for watts appear on the same listing?
Assark’s title and bullets say 50 W and the technical details say 40 W, with one review saying 20 W. MAXDONE’s listing says 50 W and one review says 25 W. Treat that as a conflict on the page, not as a tested wattage. Wait until the live listing agrees with itself.
Does 120 V on a UK page mean I cannot use it?
It means the technical details say 120 V. On Tilswall W101 that line is printed, and the raw text does not confirm a BS 1363 plug. Check the live page before you rely on it at a UK socket. Do not buy a travel adaptor. RUNSAI is the kit in this set that prints 230 V.
How do I tell a cool-melt gun from a small hot one if the temperature is missing?
You cannot. A missing temperature is n/a, not low heat. Only W101 (165°C) and W106s (170°C ± 10°C) print a figure, and both sit in the hot band. Bostik’s UK cool-melt page talks about roughly 125–135°C, which none of these kits states.
