I picked up this BESTEK 1000W inverter to keep in my truck for road trips, camping, and backup power at home. It has not disappointed me once. The build and design feels solid, the cooling fan kicks in when it needs to, and it handles everything I have thrown at it so far (within reason).I have used it to run tools, charge up laptops, and keep small appliances going when the power was out. The two outlets are handy and the USB port is quick and reliable for phones and tablets. It does draw power from the battery, so you need to make sure your vehicle is running or your battery is strong, but that is common sense with any inverter. Personally, I keep my truck running just to be sure it doesn't drain my engine battery.It runs quiet, never overheats, and has given me steady performance without hiccups. For the price, it is an easy buy. I trust it enough to keep it as part of my emergency kit and I would not hesitate to buy another one if needed.Technical Information: Total rated output is 1000 Watts with approximately 83% efficiency.At full load (1000 Watts @ 83% efficiency), the inverter will draw about 100 amps from the vehicle battery. WIthout running the vehicle to charge the battery, you are looking theoretical time of 36 minutes of runtime before the battery is depleted, but realistically, real-world expectations are closer to 15-20 minutes before the inverter blows a fuse or your vehicle battery is served well-done. I strongly suggest using a deep-cycle / marine / RV battery when using these inverters regularly unless it's for an emergency where lower wattage use is expected. For example, a typical AC-powered circular saw draws 10-15A at 120VAC = 1,200-1,800 watts. Additionally, you must calculate the initial startup surge, which can equal 2-3x the running power of the saw (momentary 2,400 - 5,000 watts). As you can see, it's doubtful that you could use this inverter for a circular saw while building your dream cabin deep in the woods. I inserted a handy chart below that may help you decide how you may want to use your new inverter.GOOD FIT ITEMS (Under 800 watts with low startup surge)Lamps with 60W LED bulbs (can run more lamps than you own (8-10 watts of power each).Dewalt Tool Battery Charger (18V/20V/24V - 50-100W)Laptops & chargers (30–100W each)Phones, tablets, USB hubs (5–30W)Small TVs (50–150W)Stereo/radio gear (50–200W)CPAP machines (30–70W without heated humidifier, 100–150W with it)Small fans (30–80W)LED or CFL lighting (10–50W each bulb or strip)Printers/scanners (50–200W, though laser printers spike higher)Small kitchen gadgets like a blender or single-serve coffee maker (300–600W, short bursts)BORDERLINE ITEMS (watch your startup surge and runtime)Mini-fridge or dorm fridge (~100W running, but 500–600W startup)Small microwave (600–700W, but surges near 1000–1200W, may trip inverter)Power tools (drills, small jigsaws, rotary tools — 300–600W range)Gaming consoles (150–250W, plus a TV)NOT PRACTICAL ITEMS (probably best to not play Tim the Tool Man with these)Any size air compressor (even the pancakes) (700-1200W with 2-3x surge)Full-size circular saws, table saws, and miter saws (1200–2000W with 2–3× surge)Full-size microwaves (1000–1500W)Toasters, hair dryers, space heaters, kettles (all 1200–1800W)AC units or anything with a compressor over ~5000 BTU
