ThruNite C2 Power Bank Review – 3400mAh Portable Charger

Trust me when I say this isn’t the first Power Bank I’ve reviewed. I have tested dozens, in all shapes and sizes. It is, however, the very first portable charger I’ve seen that actually has a removable lithium battery. This is really useful for those that own and use flashlights powered by 18650 batteries.  So, let’s take a closer look at Thrunite C2 and see if it’s worthy of a spot inside your backpack.

The ThruNite C2 Power Bank is made from machined aluminium with a sandblasted finish. The metal housing tapers slightly towards the middle and features the ThruNite logo printed neatly on its surface. The top and bottom have diamond knurled caps that help it stand out from other lipstick-sized portable chargers.

There is a threaded cap on the underside of the power bank that easily unscrews to allow the removal of the internal Lithium battery. The ThruNite C2 comes with a high quality 3400mAh capacity 18650 rechargeable battery, which can also be bought separately in packs of two.

In addition to the battery, the ThruNite C2 also comes with a mesh drawstring carry pouch,  a user manual, and a short charging cable.

I’m unsure if it’s just the one provided with my unit, or if the problem is widespread. –Please let me know in the comments below if you had a similar issue or not?

The Thrunite C2 has a 2.4A input, an impressive 3A Max output and is equipped with reverse polarity protection to prevent damage to your device. Most lipstick-sized power banks only output 1A, so this should give a considerable improvement in recharge times if your mobile device draws more than a single Amp of power.

How much charge you get from this power bank is dependent on the battery you place inside it. The Thrunite 18650 3400mAh battery that comes with it provides around 70-75% charge on my S7 Edge and should take an iPhone 6 up to around 90%. This may provide just enough extra charge to top your phone back up after a full days use.

The ability to remove the internal battery really does make the ThruNite C2 one of the most versatile small capacity power banks I’ve used. Here are a few of the benefits I can see by using this device.

Fine tuning your requirements – I’ve spent huge amounts of money on lightweight hiking equipment over the years to reduce my pack weight. The size and weight of a power bank is often a concern. On a long trip, I always take at least one high capacity power bank with me. If it’s a through-hike I really don’t have an option other than to carry it all the time. However, if I’m staying at a base camp and hiking out for the day, I can leave the large power bank at camp and take the Thrunite C2 with me. In the evening, I can recharge the C2 using the larger power bank.

A portable 18650 battery charger – Assuming I’ve brought along my big power bank for use at base camp, having the ThruNite C2 with me will allow me to recharge depleted flashlight batteries.

Making use of additional 18650 batteries – I already have two other 18650 batteries from flashlights I’ve bought over the years. If I’m planning a two-day trip and need more than the 3400mAh from the Thrunite battery, I can simply bring another one along. Carrying the Thrunite C2 and an additional 18650 battery will prove far lighter, especially if the other battery is in my backup flashlight.

I have no doubt that the Thrunite C2 portable charger will be an essential item on just about any hiking trip I take. Its ultra small size and weight make it ideal for lightweight hiking and If you already own a flashlight or torch with an 18650 rechargeable battery, then it will become even more useful.
