While both these models delivered around the same amount of energy as their competitors, they were also cheaper and more reliable than similar models. While I’ve also listed the peak (surge) power of each of these models (Wp), laptops, phones and similar electronic devices do not usually have surge power ratings, so the Wp value can generally be ignored. These models are great to keep around with you in your bag in case you need to recharge your laptop, cell phone or other small electronics in an emergency: Jackery 85W (84Wh(23200mAh), 85W, 100Wp), Omars Handheld (88Wh(24000mAh), 80W, 120Wp), Chargetech 85W Battery Pack(320Wh(27000mAh), 65W, N/A).
#BEST BACKUP POWER SUPPLY FOR MAC PORTABLE#
Ultimately, there is a wide array of portable ac power supplies available, sort of on a continuum of power delivery but for our purposes, I split my selections into 3 broad classes.įor (class 1) lightweight portable ac supplies, I prioritized portability (weight, size) first, followed by price and total capacity (energy output) in mAh or Wh (Ah x V). With that in mind, I wanted to highlight a variety of generators to suit a variety of needs and applications - there’s no point in you buying a massive Jackery 500W (or worse still, a Rainier R2200i) when all you need to do is recharge your laptop now and again during the work day conversely, the Omars Handheld is not going to be able to handle your power needs during a tailgate party or a 2-day camping trip! It’s important that you check the power requirements of your devices before buying. Starting Watts Needed = Total Running Watts of All Appliances + Starting Watts of Appliance with the Highest Starting Watts.

Your ideal portable power supply will be based on the activities you intend to use it for, and will take into account the highest starting power plus the collective running power of all your items: – while running power is the amount of continuous power your appliances need to work under normal load. Starting power (peak or surge power) is higher and can accommodate certain products that need an initial power boost to start running – refrigerators, washing machines, blenders, etc. There are 2 primary types of power an ac supply can deliver: starting power and running power.
#BEST BACKUP POWER SUPPLY FOR MAC UPDATE#
This category was in need of serious update and only 3 models from the previous list remain – the Chargetech 85W Battery Pack, the Schumacher SJ1332 and the Polaroid PS600.
#BEST BACKUP POWER SUPPLY FOR MAC MANUAL#
Always read the product manual carefully to ensure you are using it properly. Whether you go with a gas- or electricity-run power supply, be sure that it provides protection from problems like short circuits and dangerously low and high voltage. Leaving the list are the Polaroid PS600, the Prymax Portable Station, and the Jackery 85W, all of which have been discontinued.įor safety’s sake, never use a gas-powered generator, such as the Generac 7117 and the Rainier R2200i, inside your home or in a closed garage, since the fumes could be dangerous indoors. One caveat is that it’s got a modified sine wave inverter, which are known for their choppy currents that produce electrical noise and cause some devices to run inefficiently. For a budget-friendly, lower-power selection, look to the 100-watt Westinghouse iGen160s, which is lightweight and easy to carry and store, safeguards against overloads, and incorporates a handy flashlight. In addition, its battery management system helps keep the voltage, current, and temperature within safe ranges so that no harm comes to your electronics. It’s lightweight at just 10 pounds and easy to carry with the top handle.Īnother 300-watt option is the newly added Suaoki 300W, which runs efficiently and stays cool thanks to an integrated fan, and it’s got built-in emergency lights to give you peace of mind. Like most, it allows for passthrough charging, so it can be charging and provide power to things at the same time.

If you don’t need quite as much power, consider the 300-watt Anker PowerHouse II, which can be hooked up to eight devices at a time and also features a pure sine wave inverter. You can buy it with confidence, thanks to its two-year warranty. It’s equipped with a comprehensive LCD to keep you apprised of its status, as well as an ergonomic carrying handle and four sturdy feet for stability. It weighs just shy of 13 pounds and is kept lightweight thanks to its lithium ion battery. Like many on our list, it’s equipped with a pure sine wave inverter to ensure smooth running of your devices. Four new models come on board today, including the Goal Zero Yeti 500X, a versatile 500-watt choice that can be charged either through a standard wall outlet or via a solar panel.
