Not worth its price and weight. For USB-C laptops and Macbooks, it is better to buy a good 45-watt USB-C PD power bank such as RAVPower 20000 45-watt USB-C PD. For high power HP/Dell laptops dedicated HP Spectre  laptop portable chargers or Dell Notebook PowerBanks are available at lower price. For portable AC power and niche DC use such as drones and photography equipment, Omnicharge Omni 20 is much better as it offers USB-C PD and variable adjustable DC input/output. 

 On the good side, it offers the flexibility of portable AC power, USB-C, and USB ports in one package at a somewhat competitive price. It does work for charging big laptops, and AC equipment up to 70-watt, where most regular power banks cannot provide backup AC power.

On the bad side, the efficiency in AC mode is very low, AC output is about 70-watt at 110 volts, it lacks USB-C Power Delivery or USB-C input, the quality is inconsistent, the powerbank is too heavy and too expensive. If you need to power Macbook Air/Pro, you are better off buying a 45-watt USB-C PD power bank. If you really need AC power for some equipment or high power laptops, you are better off buying better Omnicharge Omni 20 for some extra price. For powering big laptops (Dell XPS 13, HP Spectre), better buy dedicated HP/Dell  laptop portable chargers that are available at same price or buy a Omnicharge Omni 20.

What We Like

  • Suitable for charging emergency AC equipment for short periods of time.
  • Can run a huge variety of AC equipment ranging from LED TVs to printers, PC monitors, fans, CPAP machines etc.
  • TSA approved. Can be carried on flights in carry-on/cabin baggage.
  • Can be quickly charged in about 6 hours flat!
  • Standard three-prong regular AC outlet
  • Two fast charging smart USB ports
  • Sturdy build
  • True 27,000 mAh capacity

What We Don’t Like

  • Very low efficiency in AC mode. Unable to charge most laptops via AC port even once
  • Inconsistent quality
  • No USB-C Power Delivery (PD) output for Macbooks. The USB-C port is non-PD and practically useless
  • No USB-C Input port for charging the power bank
  • Heavy for the battery capacity provided.
  • No USB-C Input for charging the power bank itself using USB-C
  • No direct 18-21 V DC laptop charging pins. Laptops are charged through AC outlet. Charging through the AC outlet charges the batteries of¬† laptops such as Dell XPS 13 about 50% and 12 inch Macbook Pro to about 50%. This means the efficiency is about 50-55% (around 10000 mAH)

Quick Review

Portable AC outlet with USB-C & USB charging in a sturdy package
The RAVPower universal powerbank offers portable AC outlet, USB-C & USB charging in a sturdy package

The RAVPower Universal Powerbank 27000 is a unique power bank that (on paper) offers much more versatility and flexibility than a regular power bank.

This power bank claims a world of possibilities in portable power backup by enabling you to run AC electrical appliances with up to 100 watt of required power. This includes Macbook Pros, almost all types of laptops, fans, printers, christmas lights etc..

It comes with USB type-C charging that allows you to run or charge the latest Macbook Pros or Chromebooks and ultrabooks from it directly. Running capable devices directly using USB-C is more efficient then running them using the AC adapter and allows you to maximize the powerbank’s run time.

Additionally, it comes with two smart charging USB ports that deliver up to 2.4 Amp of power and automatically sense and adjust charging current. This allows you to charge smartphones and devices such as iPads at their charging speeds over twice as fast as usual charging ports.

The 26,800 mAH capacity (nominal 2700 mAH) makes RAVPower Universal Powerbank 27000 TSA-approved and flight-safe. This allows you to take this powerbank with you in flights and power your Macbook Pros or laptops for entire flight.

All this flexibility and battery capacity comes in a sturdy solidly built package that is priced competitively with other other comparable powerbanks.

The AC outlet looks good on paper, but please be advised it is meant only for emergency use. Using the AC outlet, we could charge our 2017 Macbook Pro Just about 60%.

Fast Charging Input

Despite having a massive 26,800 mAH battery, the RAVPower Universal powerbank gets charged at blazing speed in about six hours flat as it gets charged at an incredible 19 volts! this is even higher voltage than the QuickCharge 3.0 charging which charges at 12 volts.


Design and Build

The RAVPower Universal Powerbank 27000 is solidly built with rounded sides and overall sturdy construction. This black matte-finish power bank is quite a handful with dimensions of 5.5 x 6.7 inches, 1.5-inch thickness, and a weight of 29.9 oz but given its capacity and the sheer usefulness of carrying a 100 watt AC power outlet in your pocket, it seems a fair deal. The powerbank offers total four charging ports:

Two iSmart USB ports for charging smartphones at 2.4 Amps.  The iSmart ports sense the required charging current of plugged device and deliver optimum current up to 2.4 amps.

One USB-C output port for charging latest Macbooks and laptops. No USB-C Input is supported.

One three-pronged AC outlet that can deliver up to 100 watts of AC power. The current delivered by  AC outlet depends on the wattage used. For example, at 100 watt, the current output is 0.9 Amp. Some of the countless uses for the AC outlet include running printers, Christmas lights, audio-visual equipment, fans, lights, PAP machines etc.

A huge variety of laptops, including Macbook Pros, can be charged through the AC outlet as most laptops draw about 60-100 watts of power. Please note that no direct DC output pins or ports for charging laptops are provided and laptops are charged by AC adapter.

Charging speed while charging laptops or Macbooks via AC is very poor and you cannot even charge Macbook Air from zero to 50% using AC power. Charging efficiency using USB-C is way better but charging speed is very very slow at 15-watt as the power bank lacks USB-C Power Delivery (PD) at 30 or 45-watts. Even basic Macbook Airs can be charged at 45-watt and 15-watt is simply not enough to keep the battery from going down (or remaining at same level) while working on Macbooks. Disappointing?

The AC outlet delivers 110 volt output (220 V for chargers sold in European union).

The power bank has vents for cooling for handling the high power output capability of the power bank and this keeps temperatures to normal levels despite extended use. The eight blue indicator lights are very handy for battery-level indication.

It can charge a Macbook, iPad and an iPhone at once!

This monster power bank will charge a Macbook Air 2015 about 80% with the AC port and about twice with the USB-C port. It will charge an iPhone 7 more than 10 times, and a Samsung Galaxy 7 more than 7 times. What is more, it can charge three devices simultaneously through the two iSmart and USB-C ports, allowing you to charge your Macbook Pro or Macbook Air, iPad, and iPhone at the same time!

Please note that RAVPower Universal does not support Quickcharge 2.0 or 3.0 output, it will however charge Quickcharge compatible devices at 2.4 amp fast charging current.

RAVPower Universal Powerbank 27000 vs OmniCharge Omni 20

Omnicharge Omni 20 is a direct competitor to RAVPower Universal Powerbank 27000 as both offer AC outlets in compact power bank format. Omnicharge Omni 20 has 20000 mah capacity, which is less than RAvPower Universals 27000.

RAVPower Universal Powerbank 27000 and Omnicharge Omni 20 differ greatly in battery capacity, features and price. Omnicharge Omni 20 offers many great extra features such as 60-watt USB-C PD input/output port while delivering same 100 watts of AC power same as RAVPower Universal Powerbank 27000.

A big plus of Omnicharge Omni 20 is its variable adjustable voltage DC output barrel port that can charge almost every laptop out there. It also has variable DC input feature allowing you to charge it with whatever power source you have available.

Also, Omnicharge Omni 20 gets charged in just 4 hours compared to 6 hours or so taken by RAVPower Universal Powerbank 27000.

We think that Omnicharge Omni 20 is much much better portable AC outlet portable charger than RAVPower 27000 as it offers future-proof USB-C PD output and additional multi-volt adjustable DC input/output feature. USB-C PD is quickly becoming the standard charging port of the future with latest iPhones, Samsung S/Note phones, and latest laptops supporting it.

Omnicharge Omni 20 also offer complete solar charging support and wireless charging pad function making it an excellent power backup solution for for travellers, business people, campers,  survival enthusiasts and other professional users such as photographers.

Final Verdict

Given its inconsistent quality, lack of USB-C PD, poor charging efficiency, inadequate power backup, high weight and somewhat steep price, we do not recommend RAVPower Universal Powerbank 27000.

For professionals, avid travellers, survival, outdoor and camping enthusiasts and even regular home-owners who may need a handy AC outlet in the event of power cuts or while travelling or for emergency or remote use, we instead recommend Omnicharge Omni 20 AC outlet portable charger as it offers better quality and a high efficiency DC barrel port for charging laptops directly.

If you are buying an AC outlet powerbank to power big screen HP/Dell laptops, (Dell XPS 13, 15 HP Spectre etc.), it is better to buy dedicated HP/Dell  laptop portable chargers that are available at same price. For big screen laptops of other brands, Omnicharge Omni 20 AC outlet portable charger is a better choice, though at a much higher price.
