Power your mains devices from a car, truck or solar panel
This Maplin Power Pack and 200W 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. Inverters vary in capacity and can power devices of up to a specific wattage. Inverters can be split into two categories: pure sinewave and modified sinewave.

Energy saving and safe to use
This rechargeable power pack has a built-in inverter which is powered from the internal battery and by being connected to the car accessory socket. The inverter can power a device up to 200W, such as a laptop, a rechargeable toy or a battery charger. It is highly efficient, converting 85% of its energy into output power. It is also fitted with a 2.1A USB socket for powering an additional item such as a Smartphone, Tablet or MP3 player. The inverter includes shutdown protection to power down the inverter if the battery power drops below a certain level. The rechargeable battery is charged by connecting this product to a mains power supply.

Charge your laptop or printer
This power pack and inverter is a modified sinewave inverter which produces a stepped approximation of a pure sinewave inverter, making it easier to produce. A modified sinewave inverter can power devices such as laptops, printers and chargers, although 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 1 out of 5 by from Doesn't hold the charge I am really disappointed with this product. I charged it fully before the first use and have recharged it regularly since but it only works for a few minutes before the whistling starts and it runs out of power. It doesn't even work effectively when it's plugged in. For example, if I plug a cool box into the cigarette lighter style socket, even with the invertor plugged into the mains to pre cool it before leaving home it only runs intermittently unless I leave the invertor plugged in for a while before plugging the cool box in. I bought it to run my 120 w camping washing machine which It did effectively to start with but now it doesn't.

Rated 5 out of 5 by from Excellent product,surprisingly well made, you can charge this little baby up and it gives you "wireless power" at 230v (200w maximum) and 2 12v cigarette lighter outputs and a USB device charger for as long as the batteries hold up....listening to the radio/CD or whatever in the garden, shaving in the bathroom or to work in a location with no 230v etc. Also included is a handy LED "torch" built into the facia for emergency power outages, map reading (and general seeing in the dark!) etc. Don't expect miracles but this is a very handy device for the car and the home and very,very good value IMHO.

Rated 4 out of 5 by from Does the job No sockets in the only place to set up a model railway, and the house comes with the job, so can't really fit one, and don't want trailing wires. Bought this unit a few months ago, and use it to run them. Bit mad taking 12v battery power, converting up to mains power and and converting it back down again to run the trains, but it works. You don't get a long time with it - couple of hours, which is long enough for me - and it is very simple to charge up between use. I found the fan was surprisingly quiet, contra some of the other reviews. NB, this is not suitable for use as a jump starter.

Rated 4 out of 5 by from It feels and looks a bit like a plastic toy rather than a piece of electrical equipment!To be fair, it has performed adequately on the few occasions i have used it.

can i use this for my espresso portable machine (12-24v /120w, works in car with cigarette-lighter plug)? I’m looking for the the smallest and lightest battery built in cigarette-lighter plug and compatible with my machine.

Asked by: noor
Yes this would have worked if the item has a 240v UK mains plug, However the item is now discontinued.

Whenever I charge it up and flip the invertor switch it uses all its power in half a second. Even if I turn on the light it dies in 3 seconds. Can you please advise

Asked by: DannyPhoenix
I'd say the battery has expired or the unit is faulty. If it's under guarantee I would advise you return it.

Does anyone know how long the battery lasts for

Asked by: Ian125
The unit has 2 x 6V 5AH Rechargeable Sealed Lead Acid Batteries. They are wired in series to give you 12v with 5AH (amp hours) How long they last will depend entirely on the amount of power you draw. 0.5 amp draw would last approx 10 hours 1 amp draw would last approx 5 hours 2 amp draw would be approx 2.5 hours It all depends how much power the item you have plugged in is consuming.
