While charging you phone with a power bank, you may have often wondered – what if I could also charge devices that need AC wall socket also with my power bank. The good news is that many such power banks with an AC wall outlet – in addition to USB charging –  are available in the market. You can use these power banks featuring portable wall outlets to charge ANY of your electrical devices that draw up to 100 watts of power!

The catch here is that portable powerbanks, which only have an AC port, have very high weight-to-battery ratio due to low efficiency and are NOT the best option for laptops. Small AC powerbanks are only suited for specialized professional equipment as well as equipment such as CPAP machines that do not have a DC input option. For laptops/Macbooks or any other equipment with DC input option, your best bet is to choose powerbanks with high-voltage DC barrel port output or with dual HVDC+AC ports or USB-C PD powerbanks.

The high expense on an AC Power outlet powerbank  is  worth it for professionals or individuals who may need that few additional hours on the their electronic/camera equipment to finish that vital project or assignment in the field.

There are a number of manufacturers offering AC powerbanks with the market exploding in the last 5 years. For this article, we will focus on the one that began offering portable power outlets in an extremely small form factor, making it possible to carry around such power banks with you. This is the Omnitech’s Omni series power banks with AC outlets, as well as USB-C and USB outlets, available in battery capacities of 20,000 to 38,400 mAh.

100-watt AC/DC, 60-watt USB-C Power bank Review

4 Stars

Review Summary: Latest Omni 20+ 20000 compares well with competition such as the Anker Powerhouse 100. Both power banks support 100-watt AC output and cost nearly the same.

 We recommend Anker Powerhouse 100  if you require up to 45-watt USB-C PD output for Macbooks/laptop, and prefer 30% higher capacity (27,000 mAH) compared to Omni’s 20000mAH. 

We recommend Omni 20+ 20000 if your laptop does not support USB-C charging or if you need higher 60-watt USB-C PD charging. Omni’s 100-watt DC port charges all laptops, CPAP machines, Drones etc. With highly-efficient direct DC output,  Omni 20+ 20000  delivers charging for all major laptop brands, even those without USB-C port charging support.

Omni 20+ vs. Anker PowerHouse 100 AC Power bank

Anker Powerhouse 100  is direct competitor to Omni 20+ 20000 mAH and also our top pick as portable AC outlet or laptop powerbank. Anker Powerhouse 100  is a slightly superior product that beats Omni 20+ 20000 mAH when it comes to capacity, versatility and build-quality.

Both Anker Powerhouse 100  and Omni 20+ 20000 mAH  offer 100 Watt power output allowing you to run more heavy loads and AC equipment.

Anker Powerhouse 100 offers 45W USB-C PD power output while Omni 20+ 20000 mAH offers up 60 W. However, Anker Powerhouse 100 offers 100Wh battery while Omni 20+ 20000 mAH  has a smaller 70Wh battery.

Both power banks have USB-type C ports allowing you to charge latest phones such as iPhone 13/12/11 series and Samsung Galaxy S21, S20, Nintendo Switch, the latest Macbooks and laptops directly using the power banks. USB-C ports also offer much higher charging efficiency compared to charging your Macbook/Laptop through AC power.
