CREATE THE ULTIMATE POWER SYSTEM: Pair the PowerTop with the ultra lightweight and durable 180w BainTuff Foldable Solar Blanket, plug the blanket directly into the PowerTop and it will supply up to 10A of reliable power to keep the PowerTop’s 100Ah gel battery charged. While on the move, a DC-DC charging system like the CTEK D250SA will recharge, maintain, and extend the life of your auxiliary battery via your alternator, or utilise the solar input while set up at camp, giving you the freedom to live the good times for longer.  





Always charge before use. Correct charging will ensure you get the best life out of your 100ah GEL Battery. We don’t recommend deeply discharging the PowerTop, as this will reduce the life of the battery. It is recommended to use a charging source to keep the battery topped up – the perfect off-grid option is to utilize either method of solar or alternator charging.

 Battery charge guide

Never store a battery in a discharged state. Sulphation can occur when the battery is left around for long periods in an unused state causing it to loose capacity. Letting the battery voltage fall lower than 50% or 12.4 should also be avoided.


An unused fully charged battery should sit on a reading of 12.8 volts for a couple of weeks before needing any further recharge. Store in a dry cool place, and always fully charge your PowerTop via the AC internal charger before each use.


It’s important to remember that although your battery may be rated at 100amphour, exceeding a depth-of-discharge beyond 50% won’t do it any good. For a 100 amp-hour battery, you should base your amp draw calculations off a 50 amp-hour of useable capacity. 50 amp-hours of usable capacity would mean that you could discharge 1 amp of current for 50 hours, or 10 amps for 5 hours, 6 amps for 8.3 hours – all depending on the amp draw of your accessories.




1. How do I charge the Power Top when the battery is dead?

You have to charge the Power Top through an external charger through the Grey Anderson plug. The CTEK MXS15 (CT15000/12) is the recommended charger for the Power Top.

2. Can I jumpstart my car from the Power top?

The PowerTop is not designed to jumpstart a car. The unit has a 50amp current limit inside which is not enough to jumpstart a car with.

3. Can I charge from an external ciga-socket fitted in my car?

This is not recommended as the start-up charger of the PowerTop may blow the fuse in the ciga-socket. However, some vehicles have ciga plugs rated up to 15amp, if they are rated this high it can be charged with it.

4. Do you have diagrams for the Anderson plugs?

All diagrams to do with the Anderson plugs can be found in the user manual in the charging section. It will show the application of each Anderson plug.

5. Do they have a solar power regulator?

Yes, the internal solar regulator is using a voltage control relay system.

                Solar panel unregulated = Red

                Solar panel regulated = Grey

6. Why does it flick between boost and float while charging?

This is standard operation on the 2nd and 3rd model. The lights are regulated by voltage which toggles towards the end of the charge cycle. The toggling happens when the battery is almost fully charged.

7. Can I use the sockets on the front if I am charging?

No, using the sockets at the front while charging through the 240v socket will result in the battery not charging, and draining through use. However, one can do so if you use an external charger (around 15amps) plugged into the Grey Anderson socket, or a larger solar panel (at least 150 watts or bigger) plugged into the Red Anderson socket. Either will supply enough current to sustain battery charging while using appliances.

8. How do I connect my dual to the Power Top?

The electronics in the blue socket are different and the CTEK 250S Dual needs to connect straight across the internal battery which is accessed through the Grey socket.

9. How do I know how full my battery is?

A general gauge for this is >12.8 volts is 100% full; 12.6 volts is 75% full; 12.4 volts is 50% full; 12.2 volts is 25% full and 12.0 volts is empty.

10. How do I stop the alarm going off?

You can’t other than keeping the battery charged up. The alarm goes off at 11.0 volts or less. Ideally you should not drain the battery below 12.4 volts DC to get the best life from it.

11. What is the max temperature the Power Top can withstand?

Temps up to 50° C however this is not recommended for long periods of time. This also applies to freezing temperatures.

12. What is the highest voltage the Power Top will reach?

14.2 volts is usually the maximum voltage your PowerTop will reach.

13. What does it mean when the mains light is flashing?

This happens when the battery is heavily discharged. There is a sequence to charging the Power Top through 240v. Make sure the wall unit is off as well as the Power Top. Once everything is plugged in and ready to go turn the wall unit on first and then turn the Power Top on.

14. Does the Power Top come with a VSR (Voltage Sensitive Relay)?

No but it does have a Low Voltage Alarm. It will start at 11.0 volts.
