Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For a switch panel, safety means protection features and certifications the listing actually states; a panel that states none scores zero on that line, whatever its USB watts. Two of the five panels state a warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Hapytrip 4-in-1 USB Panel | 9.7 | 32 | 22 | 21 | 5 | 2 |
| Kohree 6-Gang Switch Panel | 9.6 | 30 | 21 | 20 | 9 | 0 |
| Nilight 4-Gang Switch Panel | 9.5 | 30 | 21 | 22 | 0 | 0 |

| RVMARINEPAT 4-in-1 Panel | 9.4 | 29 | 20 | 21 | 0 | 0 |
Scores start at 9.2 for the lowest totals and top out at 9.8. In between, a kit’s position follows its weighted points one to one in order.
How to choose the best 12v usb outlet switch panel for boat
Count the switches first
Switch count is the first fit check. The Kohree panel has six rocker switches, the Nilight panel has four, the Hapytrip and RVMARINEPAT panels have one toggle each, and the Nilight rocker outlet has no switch at all, since it is an outlet only. Match the count to the circuits you want to control from one panel.
Check the USB watts
USB power varies more than the panels do. The Hapytrip panel states three USB ports at 78W total, with PD30W, PD30W and QC18W, while the Nilight and RVMARINEPAT panels state 4.8A dual USB and the Nilight rocker outlet states 4.2A total, with 2.1A in each port. The Kohree panel states dual QC 3.0 USB with no watt figure, so its charging speed is unstated. See our best 12v rocker switch panel with usb c guide for more panels with USB-C.
| Panel | USB ports | USB power | Switches |
|---|---|---|---|
| Hapytrip 4-in-1 USB Panel | 3 ports | 78W total | 1 toggle |
| Kohree 6-Gang Switch Panel | 2 ports | QC 3.0, no watts stated | 6 rockers |
| Nilight 4-Gang Switch Panel | 2 ports | 4.8A total | 4 rockers |
| Nilight Rocker USB Outlet | 2 ports | 4.2A total | None |
| RVMARINEPAT 4-in-1 Panel | 2 ports | 4.8A total | 1 rocker |
Read the protection list
Two panels here state protections, and three state none. The Kohree panel states 15A fuses with short circuit, overload, over-current and reverse polarity protection, plus CE and ROHS certification and an IP66 code. The Hapytrip panel states over-load, over-current and short circuit protection, and says the outlet is certified without naming the certification. The Nilight, RVMARINEPAT and rocker outlet listings state no protection feature at all. See our best 12v rocker switch panel with circuit breakers guide for panels with breaker protection.
Check the voltmeter
Every panel here has a voltmeter except the Nilight rocker outlet, which is a USB outlet only. The Nilight 4-gang panel builds the voltmeter into the center of the USB charger, the Hapytrip panel uses a blue LED voltmeter, the RVMARINEPAT panel uses an LED digital voltmeter, and the Kohree panel uses a blue LED digital voltmeter display. A voltmeter you can read at the helm beats guessing the battery state.
Sizing Notes
- Match the switch count to your circuits: 6 rockers on the Kohree panel, 4 on the Nilight panel, and 1 toggle on the Hapytrip and RVMARINEPAT panels.
- Match USB power to your devices: 78W total on the Hapytrip panel, 4.8A on the Nilight and RVMARINEPAT panels, and 4.2A on the Nilight rocker outlet.
- Check the voltage range: 12V to 24V on every panel here.
- Check the protection list: 15A fuses and four protections on the Kohree panel, three protections on the Hapytrip panel, and none stated on the other three panels.
- Note the voltmeter: every panel here has one except the Nilight rocker outlet, which is a USB outlet only.
