The 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.

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. HetoGrow also offer 6 months standard warranty. You deserve the best.

HetoGrow Test of Quality and OriginalityBeware of similar power banks claiming to offer 20k, 30k, 50k, 60k mAh, etc. It is impossible to pack such capacity into this size. 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. Buy HetoGrow quality.
