RavPower PowerStati­on Series

£99 inc VAT •


You know those portable power banks you carry in a pocket and have just about enough juice to fill up your phone, but then you forget to refill them and they are quickly lost, pinched or forgotten about? This isn’t one of those power banks. Not even close. The RavPower PowerStati­on Series 20,100mAh Portable Power Outlet sits at the opposite end of the power bank market, and with a £99 asking price it’s not for those who simply want their iPhone to last a full working day. Though keeping your iPhone going several days is one of many strings in its bow, the RavPower is totally OTT for that. Let’s start with the obvious: at 146x69x69m­m this power bank isn’t going to fit in anyone’s pocket. RavPower instead supplies a soft mesh case for carrying the power bank and necessary cables, plus a tough zip-up case that can hold it and the required external DC charger. We also found a carabiner clip in the box, which can be attached to the strap on the case. There are two reasons for its size: first, it is a huge capacity 20,100mAh (74.37Wh) power bank with enough juice

to fill an iPhone 7 six times, a Galaxy S7 4.5 times, or even a 12in MacBook 1.3 times; second, there’s lots of clever charging tech inside.

The key difference between this power bank and those that cost a fifth of the RavPower’s price is the 65W three-pin AC outlet and 19V/1.6A DC input. It might have a huge capacity, but over the DC input it will charge in just four hours. By comparison a standard power bank of this capacity would take at least 10 hours to refill. Meanwhile, the plug socket on top lets you plug in and power anything from drones and action cameras to printers and laptops, provided they draw less than 65W.

This is the second 65W AC/DC power bank we’ve reviewed (see our Omnicharge review at, but the first to come with a UK three-pin plug. An adaptor is also supplied in the box if you live or will be using the RavPower outside the UK. You can also buy 100W AC/DC power banks, but expect these to cost more.

The AC outlet is an emerging technology for power banks, but currently priced out of many people’s budgets. That’s a shame, because with it a power bank is able to do a lot more than power a phone, tablet, smartwatch, camera or USB-C laptop. An AC outlet can be used for any type of device with a plug, but when it comes to devices that charge over USB carrying a simple cable is much more appealing than an entire power supply.

For phones, tablets and other USB gadgets there are two USB outputs: one USB-C, which runs at 5V/3A, and one 5V/2.4A iSmart USB output. Slightly disappoint­ing is the fact the two cables supplied in the box are both USB- to Micro-USB and not USB-

to USB-C or USB-C to USB-C. There’s no support for Quick Charge but both are fast-charging ports, with the iSmart output able tor recognise the type of device plugged in and deliver only so much power as it requires.

To switch from USB power to the AC outlet you simply press and hold the power button for three seconds to turn it on. This can also be tapped to show how full is the power bank, with five LEDs in a strip around its belly each representi­ng 20 percent, or 4020mAh. In reality it’s not quite 4020mAh, because not all of that 20,100mAh is available to your devices. Some energy is always lost through heat and voltage conversion, and the industryst­andard efficiency rating is around 65 percent.

We have seen power banks that go as high as 90 percent, such as the aforementi­oned Omnicharge, but the RavPower is not one of them. This means that despite its lower 13,600mAh capacity, there is very little difference in the usable capacity of the Omnicharge and the RavPower. It also means that with a larger battery the RavPower is a bigger and less easily portable device.

Despite its size, we prefer the RavPower’s tall, cylindrica­l, Red Dot Design award-winning design. The soft-touch rubbery finish and rounded corners make it seem less unwieldy and prone to damage, while the plastic strip running around its middle that holds its LEDs is a nice touch. We also like the fact the AC outlet is covered to prevent dust getting in, and the

inclusion of small vents running around the top and bottom for improved heat dissipatio­n. Plus you get the usual overcharge-, short circuit- and current surge protection built in.

The tough carry case is a very welcome inclusion given the rather bulky power supply, but we don’t think you need it for anything other than keeping together the RavPower and its accessorie­s. It has a partly plastic constructi­on, but it feels as tough as any metal power bank. Should you require it the PowerStati­on comes with an 18-month warranty, with a card in the box (at least with our sample) offering to extend this to 30 months for free.


It has a similar usable capacity to the similarlyp­riced Omnicharge, yet lacks its LCD screen and is much larger and less easily portable. However, this RavPower PowerStati­on Series 20,100mAh Portable Power Outlet is much easier to get hold of in the UK and even comes with a UK three-pin AC outlet. Both devices are expensive at around £100, but offer insanely fast charging (and recharging) of almost anything you like. Marie Brewis
