Two batteries for SUP electric pumps compared on battery life, pump compatibility and recharge time, with a spec table for each.
Most SUP electric pumps run off a 12 volt car socket, which is fine until you park anywhere that is not next to the water. A portable battery with the same socket solves that, and the two here cover the two ways of doing it: a large 288 Wh pack for a full day of inflating and deflating, and an 88 Wh pocket-sized one for a single board.
Batteries for SUP electric pumps: what actually matters
Three numbers decide whether a battery works with your pump. The socket has to be a real 12 volt car socket, because that is the plug on nearly every SUP pump. The current limit has to be high enough, and both packs here allow 10 amps, which is 120 watts. And the capacity in watt hours tells you how many boards you get per charge: a pump drawing around 100 watts for six minutes uses roughly 10 watt hours, so the arithmetic is easy once you know your pump.
Check your pump’s rating before you buy either of these. A pump that draws more than 10 amps will trip the protection on both packs, and that is a specification the pump maker prints on the housing.

The two batteries in detail
- Capacity288 Wh
- BatteryLiFePO4 with five layers of protection
- Pump socket1 car port, 12V at 10A
- Total output300W DC, up to 140W per port
- Other ports2 USB-C PD3.1 at 140W, 2 USB-A at 12W
- Rechargingdual USB-C 140W, car at 110W, solar at 110W
Best for: A full day of paddling, several boards, or a group sharing one pump
This is the pack to buy if the pump is not the only thing you want to run. Two hundred and eighty-eight watt hours of LiFePO4 with a 12 volt car port at 10 amps covers the pump, and the two 140 watt USB-C ports handle phones, cameras and a laptop on the same charge.
Two details matter beyond the capacity. LiFePO4 chemistry lasts through many more cycles than the cells in budget power banks, which is what you want in something that gets a hard 100 watt draw pulled through it several times a day. And the recharge is fast enough to matter: 80 percent in 85 minutes means you can top it up over lunch. The one thing to confirm is that your pump does not exceed 10 amps.
Pros
- 288 Wh is enough for many inflations of a normal SUP, so the pack is not the limiting factor
- A LiFePO4 cell tolerates far more charge cycles than the lithium polymer cells in cheaper packs
- 0 to 80 percent in 85 minutes over two 140 watt USB-C ports, so it recharges between trips rather than overnight
- The 12 volt port is a proper car socket at 10 amps, which is what SUP pumps expect
Cons
- It is DC only, so there is no AC outlet for anything with a wall plug
- EcoFlow does not include a charging cable in the box
- The most expensive option here by a wide margin
- Capacity88 Wh
- Pump socket2 DC ports, 12V at 10A
- AC output2 sockets at 110V, 120W, 240W peak
- USB1 USB-C at 18W, 2 QC 3.0, 1 USB-A at 5V 2.4A
- Size and weight6.6 x 4 x 3 in, 2.3 lbs
- ChargingAC adapter included, car charger included, solar 15V to 24V
Best for: One board, one inflation, and a pack small enough to leave in the car
The HOWEASY is the small answer. Eighty-eight watt hours, 2.3 lbs and a hidden handle, with two 12 volt DC ports at 10 amps each, which is exactly the socket a SUP electric pump plugs into.
Its argument is that most people inflate one board and go paddling. For that job the extra capacity of a 288 Wh pack is dead weight in the car, and the price gap is more than the pump itself costs. Charging is flexible too: the AC adapter and the car charger both come with it, and it will take a 15 to 24 volt solar panel if you have one. Just do the arithmetic on your own pump before you rely on it for more than one board.
Pros
- At 2.3 lbs and about the size of a paperback it goes in the same bag as the pump
- Two 12 volt 10 amp DC ports, so a pump and a cooler can run at once
- The AC adapter and the car charger are both in the box, unlike the EcoFlow
- Two AC sockets at 120 watts, useful for chargers that have no 12 volt version
Cons
- Eighty-eight watt hours is a fraction of the EcoFlow, so plan on one board rather than a day of them
- HOWEASY does not publish the cell chemistry or a cycle rating
- The 120 watt AC limit rules out most mains appliances
Checklist: What Makes a Great Battery for SUP Electric Pumps
- Battery Life: Select a battery that provides ample energy to inflate multiple SUPs per charge, ensuring prolonged activities without needing to recharge constantly.
- Compatibility: The ideal battery should support a variety of devices and pump connections, including both USB and 12V outputs, catering to different types of equipment and accessories.
- Recharge Time: A practical battery has a reasonable recharge time balanced with its capacity, featuring smart technology like auto-stop to prevent overcharging and prolong battery health.
- Portability: For convenience, choose a lightweight and compact battery that is easy to transport and pack, without compromising on its power capabilities for your paddling escapades.
- Durability: Look for rugged construction suited for outdoor usage, preferably with water-resistance or protective features, ensuring longevity and reliability in various conditions.
- Safety Features: Safety is important; thus a battery with built-in voltage protection guards against potential overloads or short-circuits is essential for a worry-free outing.
