Haier Thermocool TEC GEN – Major 3500ES – Specs Review and Price

Our Take: Haier Thermocool has been well known as a brand of electronics in Nigeria for many decades, so when they decided to start making generators, we knew it should be reliable. Though slightly bigger than the CAPTAIN here) this is an entry generator. It boasts of a 3.5kva starting capacity I would say you should be more concerned about the running capacity of 3.3kva. This generator like others in its class is a single-phase generator, meaning it will generate just one positive output line; don’t worry except you have a factory in your flat, this is mostly adequate. Using the 220v used in Nigeria, this generator is capable of supplying about 13Amps. Most of the uses will mostly be for small loads hence the reason we call it entry-level.


For load capacity, its 13A roughly translates to one 32-inch TV, 5 60W bulbs, 4 ceiling fans, one 1.5-HP AC, and a medium refrigerator(about 120L) refrigerator;  this will get your generator to about 80% capacity. Note the running your generator at the full capacity continuously will reduce the life span, increase the frequency of required service, and increase fuel consumption. The 15L tank should run for at least 8 hours at 80% load and about 10.5 hours on half load; meaning your TV, Fans, and Fridge. I can use a generator from this series so I can vouch for the fuel efficiency.

The generator can be rolled as it is with tires and has a key starting feature with the tried and tested recoil starting method. I will definitely recommend this generator for a small size household like a typical mini-flat; the capacity should be enough. Just make sure your buy at a reliable seller to make sure you are buying the original.
