Power home appliances from a truck, car or solar panel

This 24V Modified Sinewave 150W Inverter is a converter that connects to a sealed lead acid (SLA) battery that is usually connected to a car, a truck or a solar panel. The inverter can connect to the battery either through a car accessory plug or by clipping directly to the battery. A mains powered device can then be plugged directly into the inverter’s AC socket. This 24V inverter can power devices of up to 150W.

Charge your smartphone, tablet or MP3 Player
This Maplin 24V Inverter connects to the vehicle’s battery through its accessory socket. The compact design of this inverter allows it to be discretely positioned without being in the way. The inverter can power a device up to 150W, such as a laptop, a phone charger or a portable games console. It is highly efficient, converting 90% of its energy into output power. It is fitted with a 2.1A USB socket to charge a wide range of items such as a Smartphone, a Tablet or an MP3 player, while keeping the mains socket available for a different device. The inverter includes shutdown protection to power down the inverter if the battery power drops below a certain level.

Power simple appliances
A modified sinewave inverter can power devices such as phone chargers, heaters and air conditioners and other simple electronics. Some items may pick up interference from the inverter, a solution for this is to upgrade to a pure sinewave inverter. A pure sinewave inverter is used to power sensitive electronic devices such as power motors, power tools, clocks or microwaves.


Rated 3 out of 5 by from I've just had the second one of these fail on me. The same fault as before (unit replaced without argument by Maplins Lowestoft where I bought it, Impressed with their service). Blows the auxiliary power fuse in the truck. Don't know why? Only used to keep a laptop on charge through a 65 watt (Dell) charger. Good when working! I think I'll go for a 24v to 19.5v transformer next time!

Rated 5 out of 5 by from It works It's a nice cheap inverter, works a treat, had it around 6 months now and never had a problem

Rated 1 out of 5 by from Had them for 2 years, and had too many problems I bought 12 of these units for the business, and all of them but 1 have been a constant issue. From blowing the fuse in the truck, to melting the plugs and even had at least 3 of them cause a driver to have to stop and control the smoke pouring out of the connection because of heat and arcing. They only ever run at a max of 35w! Great shame, but I really don't think they are up to the job.

Rated 1 out of 5 by from Blows car fuse I bought this on the advice of a maplins shop assistant to charge a surface pro in car. It worked for a short while then emitted a high pitched alarm and blew my car fuse. Created more problems than it solved.

I have a camper van fitted with leisure batteries charged by solar power. I want to charge an electric bike battery through a cigarette lighter type socket whilst driving. The bike battery is 400w, input 100-240v ....2.5A 50/60HZ

Asked by: Steve
240 v at 2.5 A is 600w which would exceed the operational parameters of this inverter. Also this is a 24v inverter .. most campers run a 12v system The following web page can prove helpful for calculating electrical loads

Hello. Would this be ok with a slim ps2 in my car? I think the ps2 has an average usage of 24 watts. Thanks

Asked by: Vico
No, this would not be suitable. You would need a 12v Pure Sinewave inverter;
