It has been a while since I could venture into the wilderness with all the electricity I needed supplied by a single battery for my headlamp. Now on my overnight boating trips I need to power cameras, a cell phone, a GPS, a VHF, running lights, weather radio, and often a small laptop. Some devices, such as my handheld depth sounder, get by with a single battery for the duration of a cruise, but devices used more frequently—running lights, smart phone, or cameras—require either backup batteries or recharging.
In recent years I’ve carried a 12-volt deep-cycle battery wired to a cigarette-lighter socket. It worked well for recharging devices that had car chargers, but it weighed a cumbersome 50 lbs and was so often in the way that I made a foam-and-canvas cover for it to blunt the impact of my toes. When I stumbled across Jackery’s portable power stations, I quickly turned my back on my deep-cycle and bought the Jackery Explorer 160, the company’s smallest unit. Its bank of lithium-ion cells is rated to supply 167 watt hours, which is, if my calculations are correct, a 30 percent improvement over my deep-cycle battery. The Explorer 160 delivers that capacity in a 7.5″ x 4.75″ x 6.9″ package that weighs just under 4 lbs. The face of the unit has two ports for 12-volt power, one for charging the Explorer 160 with the included AC adapter or an optional solar panel, the other to supply power to electronic devices using the included cigarette-lighter socket and cord.
There are three USB ports, one USB-C and two USB-A. A backlit LCD screen in the middle shows input and output in watts, a graphic of a battery showing the level of charge, and the percent charge remaining. With each device being charged, the display screen shows how many watts are being drawn. When multiple devices are being charged, the display shows the total output. There’s an AC outlet at one end of the Explorer 160 and a built-in flashlight at the other. The outlets, display screen, and flashlight all have switches. The flashlight’s switch, if pressed and held, will make the light a flashing Morse SOS signal.
The Jackery power station isn’t waterproof, so it would need to be protected by a dry bag if carried in an open boat. It’s not meant to survive being dropped, so treat it as you would the electronics you charge with it.
For my first trial with the Explorer 160 I charged my electronics for a weekend outing. Starting with 100 percent capacity, it charged a fully dead laptop battery, a dead VHF radio, four GoPro batteries (three 1,050 mAh, one 3,400 mAh), two DSLR batteries, a Bluetooth keyboard, a flashlight/power bank, a trailer back-up camera, and my phone, and still had 22 percent of its capacity remaining. The instructions advise recharging the Explorer 160 when it reaches 20 percent. If I head out with everything topped off, the Explorer 160 can keep me going for a three-day cruise, taking a lot of photos and video and spending evenings writing on the laptop.

The Explorer 160 is available from Jackery for $159.99. I bought mine on Amazon using a $40-off coupon that appeared on the listing there. Jackery offers two larger power stations, Explorers 240 and 500, as well as two sizes of solar panels for recharging.
Is there a product that might be useful for boatbuilding, cruising, or shore-side camping that you’d like us to review? Please email your suggestions.
I’m using a similar unit, the Rockpals 300w Portable Power Station in my CLC Autumn Leaves, reviewed in the December issue. I found that it was all I needed for four days on board, running cabin lights and recharging phone, tablet and hearing aids. Next step is to install a 20W solar panel, which this unit is already set up to take a charge from.
Yes, this approach is far simpler, smaller and lighter than the electric setups I’ve had in the past, which have involved heavy AGM batteries, solar panel controllers, and a lot more wiring to link the battery to the necessary power points. The only negative I’ve found is that if the unit sits turned off for a couple of months, it loses its charge. This will not be a problem once it’s linked to the solar panel, but I did think that these types of batteries held a charge better.
I have a 27′ simple sailboat with a 12-volt system that runs running lights and two LED cabin lights. It has a switch panel connected to a small golf-cart type battery by wire leads. How would I connect it to one of these power sources. They look great.
The Jackery comes with a 12-v socket, automotive cigarette style. In the first photo above it is being used with the white USB adapter. Buy a plug to fit the socket (auto parts or electronics stores) and connect its wires to your existing wire leads. To be on the safe side, I’d make it an either/or system with switches or the wiring that allows only one power source at a time. I don’t know what would happen to the Jackery if its 12-v out plug were subject to current from your existing system.
Thanks, Christopher. My idea is to remove the existing battery permanently, and use only the Jackery.
Where can I buy that cable that you have connected to the 12v output port pictured several times in your article? I just bought the 160 and thought I had the correct cable, but I don’t.
Thanks!
I’m pretty sure the cable with the 12v car socket came with the Jackery 160, although the manual labelled its drawing of the device as a “DC inverter Cable.” The listing of “what’s in the box” on the Jackery web site no longer includes this device. This comes close: BiXPower Car Cigarette Socket to 5.5 x 2.5mm or 5.5 x 2.1mm Male Barrel Connector Adapter But the diameter listed, 5.5 mm, is smaller than the 5.9 mm diameter of what I showed in the review.
I wanted to provide an update. I contacted Jackery support and once they verified my Amazon purchase – they sent me the correct cable/adapter for no charge. Not sure why they decided to no longer include the cable/adapter, but for now they seem happy to ship if requested.
