Power adapter for 9 V devices
This KEHIPI boost converter steps a standard 5 V USB source up to 9 V DC, delivering up to 1.5 A through a 1.1 m cable. It suits users who need to run 9 V equipment such as routers, small fans or audio gear from a power bank or USB charger when mains power is unavailable.
Compact build with dual connector options
The unit weighs 35 grams and integrates a 5.5 × 2.5 mm DC plug plus a 3.5 × 1.35 mm jack adapter, covering two common barrel sizes without extra dongles. Plug-and-play operation means no configuration; the short cable keeps the setup tidy on a desk or in a travel bag.
Replaces fixed 9 V wall warts
It upgrades any situation where a dedicated 9 V mains adapter would otherwise be required, letting a single USB power bank serve multiple devices. The jump is worthwhile when portability or backup runtime matters more than the simplicity of a single-purpose supply.
