While most automakers do include portable chargers with their EVs, for those that don't a number of companies have come up with similar units you can toss in your trunk or frunk to provide juice on the go including a new one just hitting the market from tech company Fulsolen that includes several compelling new features.

With adapters, the Smart A01 can be used with an EV, according to Fulsolen. Available in both 32 and 40 amp versions the Fulsolen Smart A01 units can be used by plugging them into any electrical outlet at home or on the road.

In addition, as a means of saving power, when selected, the unit's "PV charging first" technology recharges an EV battery using solar power through a photovoltaic, or PV cell before reverting to electric power if conditions change.

Touted by Fulsolen as both a safety and power-saving feature is what the company calls the unit's "unique dynamic load balancing technology." It automatically senses how much electricity is being drawn on a home's system and adjusts how much it draws to charge the unit in order to prevent circuit breakers from tripping due to an overload.

The company says Fulsolen portable chargers are compatible with virtually any electric vehicle through the use of various connection adapters. How long it takes to replenish an EV battery's charge and how much driving range is provided both depend on the capacity of the battery and how long it's connected to the charger, according to the company. Power output ranges from 1.4 kilowatts to 9.6 kilowatts. The 32 amp unit weighs 9.7 pounds and costs $339 while the 40 amp charger weighs 13 pounds priced at $399.

The company is running an introductory sale online through Amazon websites with 32 amp units discounted 20% reducing the price to $269 and 40 amp units discounted 25% to $299.

Indeed, the ability to emulate the equivalent of carrying a can of spare gasoline is aimed at breaking down a key barrier for many consumers to making the switch from internal combustion engine vehicles, or ICE, to those powered solely by batteries.

With the national charging network still very much in its formative stages, the concern remains among motorists who intend to take longer road trips their vehicle's battery will run out of juice before they can find a recharging station on, or near their route.

That's why Fulsolen is jumping into an already crowded market as enterprising tech companies look to cash in on allaying that concern.
