A traditional maintainer takes up the space of a book and stays attached to the garage outlet. This one is 6.9 cm long and weighs as much as a cable: it fits under the seat, in your jacket pocket, or in the top case without making you decide what to leave at home.

It’s the difference between having it when you need it and having left it at the workshop.

The input is a standard USB-A port and supports up to 18 W. A phone charger, tablet charger, power bank, computer port, or portable camping power station will work.

That’s why this charger works where others can’t: in a garage without power, in the yard, or in a hotel parking lot halfway through a trip.

In everyday use, the setup is as follows: a USB power adapter plugged into the power strip, a cable running to the motorcycle, and a connector that snaps into place. No extra device to buy and no dedicated outlet to free up.

The more powerful the power adapter, the faster the charging: with 18 W of input, the charger delivers 1.25 A; with 12 W, it drops to 0.8 A; with 5 W, to 0.35 A.

Soft start: before supplying current, the charger diagnoses the battery so that any short circuit does not produce sparks. Activation: if the voltage is between 3 and 10.5 V, the battery is awakened before charging. Fast charging: above 10.5 V, charging switches to a maximum of 2 A.

It then charges at medium speed to limit the emission of acidic gases, with final absorption at a constant 14.6 V up to 100 percent, followed by automatic maintenance. Stages three and four alternate until the voltage reaches 14.6 V. You do not touch anything: there is not a single button to press.

Inside the transparent casing is a control chip with three safeguards: protection against reverse polarity, overcharging, and short circuits. If you reverse the red and black wires, it simply won't start instead of being damaged.

The limited current is part of the same principle: slow charging puts less strain on the battery than fast charging, and for a battery that has already seen a few seasons, that's exactly what's needed.

It works with lead-acid batteries, including sealed and AGM batteries, as well as lithium iron phosphate batteries. One device for every motorcycle in the garage, with no selectors to switch.

The capacity range is from 4 to 35 Ah, covering motorcycles, scooters, and ATVs. Above 20 Ah, LOBOO recommends powering it with an 18 W charger; otherwise, charging times become considerably longer.

The package includes a two-part cable with a quick-connect plug. The short section has fork terminals: attach it once under the battery terminal bolts and leave it there, with the plug extending from under the seat.

From then on, you don’t need to remove anything to recharge: connect, disconnect, and ride off. It works like a garage battery maintainer, but everything fits in your pocket.

The manufacturer states that it has passed the safety checks for the CE, FCC, and RoHS marks and the national GB standards, and displays the relevant certificates.

If you need the certificate details for type approval or an insurance claim, ask us: we will request them from the manufacturer.

Body 6.9 cm long and 3.7 cm at its widest point, with a 1.8 cm connector. The charging cable is 50 cm long, and the one with fork terminals is 126 cm long.

13 V output with current depending on the power supply: 1.25 A with 18 W, 0.8 A with 12 W, and 0.35 A with 5 W. Voltage limit: 14.6 V; battery capacity: 4 to 35 Ah.
