A Dead Battery Is Never A Mechanical Problem. It Is A Logistics Problem. Nobody plans to be in a car park at eleven at night with a bonnet open, and yet the failure mode is entirely predictable: cold, a light left on, a battery two winters past its best. The Surge Relay exists so that the outcome of that moment depends on what is in your boot rather than who happens to drive past.
The core is a high-rate polymer lithium pack with a peak discharge above 1200 amps, rated to turn over petrol engines up to 6.0 liters and diesel up to 4.0 liters. Clamps connect directly, the smart charging circuit reads the vehicle and delivers rather than dumps, and the engine catches in seconds. The housing is ABS with internal cell separation, and the pack holds its charge across temperature swings that would flatten a lead-acid spare.
The rest of the design is about the eighty-nine days you are not jump starting a car. A USB output turns the pack into a phone and tablet charger, which is what makes it worth carrying on a road trip rather than leaving at home. A USB-C input refills it without a dedicated brick. An LED array with an SOS mode covers work under the bonnet at night and the considerably worse scenario of being stranded somewhere you would rather be visible. Charge it twice a year and it waits, patiently, for the one morning it earns its place.
You will use it four times in five years. Those four times will justify the other five.

Where It Belongs
For the driver whose car sits for weeks at a time, the family with one vehicle doing school runs in winter, the rider whose motorcycle battery hates the cold, and the tradesperson whose van cannot afford an unplanned hour. It also earns its place as a general emergency pack: phone charging during an outage, lighting under a bonnet, and a second set of jump leads for the neighbour who does not own any.
Questions, Answered
Q: Will it start a diesel van or a large SUV?
The 2000A model is rated to 4.0 liters diesel and 6.0 liters petrol, which covers most vans, pickups and large SUVs. For engines above that displacement, step up to a higher-current unit rather than attempting a marginal start.
Q: Do I need to charge it before first use?
Yes. Lithium packs ship in a storage state. Charge it fully for at least four hours before the first jump start, then top it up every three months. A deeply discharged pack may refuse to deliver peak current.
Q: How many jumps per charge?
Typically eight to twelve starts on a healthy mid-size petrol engine, fewer on large diesel units. Capacity is consumed per start, so recharge after heavy use rather than relying on the reserve.
Q: Can I leave it connected as a maintainer?
No. It is a starting device, not a battery tender. Disconnect the clamps within thirty seconds of the engine catching, and never charge the jump starter and discharge it into a vehicle at the same time.
Q: Is it safe if the clamps touch each other?
The internal protection circuit guards against reverse polarity and short circuit, but the clamps should still be kept apart when not in use. Store the pack with the clamps clipped to their holder.
Q: Can I take it on a plane?
The capacity sits inside the carry-on lithium battery allowance for most airlines, but cabin-bag rules vary by carrier. Check with your airline before flying with it, and never place it in checked baggage.
