78W 12V Marine Charger

The Hapytrip SD16 is a 12V USB charger built for boats, RVs, motorcycles and similar DC vehicles. Its aluminium body and waterproof cover withstand wet, dusty environments while dissipating heat without a fan. A blue LED voltmeter and on/off switch let the driver monitor battery health and cut power to prevent parasitic drain when the engine is off.

Dual 30W USB-C plus 18W USB-A

Two PD 3.0 Type-C ports deliver up to 30W each and one QC 3.0 Type-A port supplies 18W, sharing a 78W total budget. Three phones, tablets or smartwatches charge together at full speed until the combined draw hits the limit, after which output is split proportionally. The unit accepts 12V or 24V vehicle systems and includes a 23.6-inch lead with two spare 10A fuses for DIY fitting.

Replaces a single lighter socket

The round housing fits the standard cut-out used by a factory cigarette lighter, adding three fast-charge ports and live voltage read-out in the same footprint. The upgrade is worthwhile when the original socket only offers slow 5W charging or lacks a voltmeter and power switch. It does not add extra 12V accessory sockets, so vehicles needing additional barrel-style outlets will require a separate splitter.
