1 of 3 The most technically advanced, easiest to fit, simplest to use powerpack ever. A brand leader for over 10 years and now better than ever! Although very similar in looks and function to the original model, the Series 4 Powerpack has undergone a major update to take advantage of new technology. Externally the compact motor and gearbox unit has been re-designed, although the ultra reliable internals remain the same. We have re-designed the chassis and battery bag, with matching lifting strap, added attractive alloy wheels and super grip tyres – hardly anything has gone unchanged. We have even included electronic traction control to ensure a smooth start without wheelspin. The most significant change of all is the electronic control system. This uses the very latest in micro-processor technology with a host of advanced safety features. The ergonomically designed handlebar control is a direct replacement for the standard wheelchair handlebar grips and the easy-to-use controls feature very important handlebar extensions and optional left or right hand use. The key which operates the on/off switch is removable for safety and security. There is an on/off light with red, amber, green colour sequence advising battery condition, a pre-set speed control governing top speed and a thumb-operated speed control lever. Alternatively the lever can be used in conjunction with the pre-set control to provide simple press button operation. The range has been expanded to include three models. The standard single wheel version capable of transporting up to 18 stone user weight. The standard twin-wheel model with the same user weight limit but much greater traction – really effective on loose gravel and wet grass. The heavy duty version is only available with twin wheels and is capable of transporting up to 26 stone. All of the fittings have been improved for greater ease of use and the Powerpack attaches to any wheelchair in literally seconds. Once fitted you will never need to push the chair again. Simply walk behind with your thumb on the control and let the Powerpack do all the work for you. No more struggling up hills, ramps or uneven ground; just press the lever and enjoy the effortless transportation the Powerpack provides. With speeds up to 4mph and a range of up to 10 miles, there is more than enough capacity for most days out. It’s light enough to take anywhere, packing neatly into a travel bag and enabling you to have that extra mobility from car boot and coach, to train, boat and plane.  Technical Specification Motor (standard) 12v 160w Motor (heavy duty) 12v 200w Total Weight (inc battery) - Standard 13.0 kg Total Weight (inc battery) - Heavy duty 16.0 kg Total Weight (inc battery) - Twin wheel 14.5 kg Battery Weight 6.9 kg Battery Capacity 12v 20ah Tyre Size (Solid Tyre) 2.00 x 5 Max Speed 4 mph Range * Up to 10 miles Max User Weight - Standard 18 stone Max User Weight - Heavy Duty 26 stone *  Range of the TGA Powerpack can vary depending on the user weight and the conditions such as terrain.  When choosing model, weights specified are combined weights of the occupant and the wheelchair.
