Spigen Essential F720S Power Bank – Full Review

As with all Spigen’s ‘Essential’ range of products, the F720S Power Bank comes in a well presented black and orange coloured retail box. Inside, there’s a user guide, a good quality padded drawstring pouch and a branded charging cable.

The charging cable measures around 12 inches, which is a little on the short side. It’s fine for the purpose of recharging the power bank, but I do prefer a longer cable when I’m charging my phone or tablet.

I recently got a 1.5m long 3-in-1 cable from Spigen, which has a regular USB, Type-C and Lightning connectors.

No doubt you’ve got USB cables coming out your ears, but I have found owning a high quality braided universal cable to be an unexpected luxury. I might get a few more and cull the dozens of generic ones I have laying around.

Surprisingly Compact

The Spigen Essential F720S power bank is slim enough to be considered pockets size – as long as they’re deep enough.  The matte black plastic housing has rounded sides, making it comfortable to hold and carry around. There are five small battery indicator lights on the front, a button on the side to check the remaining power level, and all the ports are found at the top.

There’s a micro USB input, a Qualcomm Quick Charge 3.0 port and an intelligent port that goes up to 2.4A. The QC3.0 port can be safely used to charge any device whether it’s got Quick Charge technology or not, it’s also backwards compatible with QC2.0 devices.

It weighs a total of 357g (12.6oz) which is about as light as you’ll get for a power bank with over 20000mAh of capacity. It’s also surprisingly compact measuring 168x63x22mm (6.5×2.5×0.9 Inches).  I own a ridiculous amount of high capacity power banks and this one is the smallest of them all.

I’m actually preparing for a trip away and I’m taking three high capacity power banks along with me. It sounds excessive, but with two young boys each with tablet and phones, a single power bank is not going to be enough. I’m recharging them as I write this review, take a look for yourself, the size difference is significant.

In their defence, they do have more USB outputs than the Spigen power bank. From experience, however, I rarely have a need to charge more than two devices at the same time so I’m happy to ditch a couple of outputs in favour of a smaller device.

Features and Performance.

Specifications and features of the Spigen power bank

Pass-Through charging

Despite the very reasonable price tag, the Spigen Essential power bank supports pass-through charging. This is something that’s typically found on more expensive portable chargers like the Zendure A8. This means you can safely connect devices to the power bank as it’s recharging. This can be a really useful feature especially if you don’t have a charging station with multiple outputs.

Built-in Safety

The Spigen F720S power back is designed to protect itself from overcharging as well as your connected devices. It features short circuit protection and will automatically shut down if there is an overload or an overheating problem. It also comes with a 2-year warranty for additional peace of mind.


With its intelligent power technology, the Spigen Essential power bank is compatible with just about all portable devices that require 2.4A or less. These include popular phones like the Samsung Galaxy S9/S9 Plus/S8/S8 Plus/Note 8, the iPhone X/8/7/6/SE/5, Huawei Mate 10/P10/P9, OnePlus 5, Sony, HTC. It will also charge Tablets, iPads, the Nintendo Switch, and smaller devices like the GoPro and Bluetooth headphones.


It’s early days regarding how efficient this power bank is in comparisson to some of my tried and tested favourites. Early signs are looking good though. I’ll be sure to update this review with exact details of how many charges I’m getting from a full battery. I have a strong feeling it will appear very near the top of my list of the best 20000mAh power banks in the very near future.

The Spigen Essential F720S power bank is an awesome high-capacity portable charger for the money. Ideal for those with a couple of power-hungry devices. It’s compact enough to carry around and has enough juice to give you 4 or 5 full phone charges. Its pass-through charging and quick charge 3.0 compatibility make it seriously good value and certainly worth the price tag.
