The COSLUS C30 Electric Toothbrush for Adults and the 7AM2M Sonic Electric Toothbrush for Adults, Type-C Charging score the same, so either is a safe pick. The COSLUS C30 Electric Toothbrush for Adults goes first because it leaves owners a little happier.
The C30 is a rechargeable sonic toothbrush for adults. Its listing describes a magnetic levitation motor, five cleaning modes and three intensity levels (low, medium, high) that can be set in each mode. The brush heads come in soft and firm types, and the listing gives the bristles a life of more than three months.
It charges through a 5V DC input in about two hours. The listing says a charging adapter is not included, but any 5V adapter works. The built-in lithium-ion battery is listed as lasting 30 to 150 days, depending on the mode used. The body is rated IPX7, so it can go in the shower. It measures about 7.2 inches long and about 1 inch across.
One thing to check before you search for a manual or spare parts: COSLUS also sells a product called the C30 that is a cordless water flosser, not a toothbrush. The brand's own site shows the flosser under that name and does not show this toothbrush, so the specs here come from the listing details of the toothbrush rather than a brand spec sheet.
Owner feedback for this exact model is thin, and the sources open to us cover only a handful of owners. Those who wrote about it call it quiet and good value, and say it cleans well for the cost. Several liked the battery life, and some mention it travels well.
Opinions on strength differ. One owner found the vibration subtle, while another found the top setting strong. One owner thought the handle is large for a toothbrush. One compared it favorably with a far pricier Sonicare-type brush, and another felt Philips is better made.
Nothing we found speaks to how it holds up after many months of use.
The C30 fits someone who wants a basic rechargeable brush at a budget price, likes choosing between several modes, and wants a battery that goes weeks between charges. Replacement heads are cheap, which helps over time.
Look elsewhere if you want a pressure sensor, a brand with detailed support information, or ADA acceptance. The Philips Sonicare 4100 is a better fit if you want a better-known sonic brand at a similar budget. The Oral-B Pro 1000 suits those who prefer an oscillating brush. Shoppers who want a kit with spare heads and a case could look at the kingheroes set.
Both exist under the name. COSLUS sells a C30 cordless water flosser, and this review covers the C30 electric toothbrush for adults. Check the product title before you buy a manual or replacement parts.

Every score here comes from our ranking model; no editor sets the order. Too few review sites cover electric toothbrushes for their verdicts to lead, so this ranking is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 20 models for this guide before settling on these ten.
Brands can't pay to be included or to move up. We last checked these picks in November 2026.
