What capacity should you buy?
It is strange that many people don’t read quality and product specifications. They develop unrealistic expectations of what a product should do. When they have problems they blame it on the product or call us to complain. For instance, a university PhD Engineering lecturer called us some time in 2015 to complain. When we asked him if he read the user manual he said no. He later apologised after much discussion. On another occasion a customer called to complain that the product wasn’t working. We asked her same question and she said no. It turned out she never pressed the power button.In the very rare occasion of genuine manufacturing fault, we provide like-for-like replacement in line with our warranty terms. Before you complain, we STRONGLY recommend that you read the product specs and the below notes on quality. We are very happy to discuss if you contact us. Quality SpecsThe primary consideration in designing HetoGrow products is quality and safety. A further emphasis is placed on affordability. Both factors impose obvious limits on what we can possibly pack into the products. One limitation is uncontrollable FX rates which affect prices. Another obvious limitation is size. The fact that a HetoGrow solar power bank is a mobile product limits what can be added to it hence what it can do. An example is the solar panel. The larger it is the more it can charge. It is not magic but a universal reality. Its primary purpose is to top up the power bank on exposure to light. Because of the limited size it is unrealistic to expect it to perform like a roof top solar panel. This mobile size also limits the capacity rating (mAh). It can realistically contain 10-12,000 mAh. Be cautious of look-a-like but typically fake and unbranded products offering 20k, 50, 80 mAh, etc, similar to the capacity of a standard car battery. For detailed information about this see our Quality Assurance webpage.HetoGrow solar power banks are especially designed to recharge mobile phones with USB cables and provide highly efficient and renewable LED flashlight. They provide safe and sustainable bright light after charging with either sunlight or electricity. Each power bank is supplemented by the embedded solar panel during the day. This provides solar support and emergency power back up as it recharges the power bank on exposure to the sun. The product is designed to support mobile phones and up to 5V devices where there is no access to electricity. It is mobile ready and ideal in emergency situations like when outdoors in remote places, camping or even at a business summit.HetoGrow solar power banks are equipped with in built anti discharge technology that retains energy for over 12 months.

Below are some tips to bear in mindThink! Your standard smart phone battery is typically 2500 mAh on average.20k mAh is equivalent to 8 smart phone batteries.60k mAh is equivalent to 24 smart phone batteries. It should therefore be heavier.100k mAh is equivalent to 40 smart phone batteries. It should also be heavier.However, weight isn't a guaranty of quality. Bags of sand and other rubbish have been found in some of them.Top brands don’t offer these unusual and strange capacities for similar size of power banks. Think of the reason why.Ask yourself, can 8 ,24, 40, etc batteries be of the same weight & fit into the power bank case?Beware and do these basic checks before you buy.
