The Best Option When Profile Size Matters

The UGREEN 4-Port Slim hub earns its spot in this review for one reason: it is noticeably flatter than every other hub here. For buyers with tight desk setups -- a monitor arm that leaves little clearance, a desk mat that runs to the edge, or a cable management system that restricts hub height -- the UGREEN's slim design is a meaningful advantage, not just an aesthetic preference. With strong buyer feedback, it also has solid buyer backing for a hub in this price tier.

As a bus-powered 4-port hub, the UGREEN is built for the devices most people connect: flash drives, wireless keyboard and mouse receivers, and other low-power peripherals. The trade-off is the housing: ultra-slim designs reduce material thickness to achieve the flat profile, so it will feel lighter than a traditional hub.

Pros and Cons

Pros

  • Strong feedback with good buyer evidence
  • Ultra-slim design is the flattest form factor in this category
  • USB 3.0 on all four ports
  • Priced competitively -- one of the lowest-priced USB 3.0 hubs in this review

Cons

  • Ultra-slim design means a thinner, lighter housing than traditional hubs
  • Bus-powered, so it is not suited to charging phones or running several external hard drives at once

Bottom Line

Buy the UGREEN 4-Port Slim Hub if profile size is the deciding factor. With strong buyer feedback it has solid backing, and the ultra-slim form factor is genuinely useful in tight desk setups. For buyers where compactness is not a constraint, the SABRENT Best Overall pick offers more per-port control at a similar price.
