Tecknet iEP1500 Power Bank Review – Bicycle Touring Gear

Recharging tech gear when bicycle touring can sometimes be a bit of a pain, and so I bought the Tecknet iEP1500 Power Bank 15000 mAh External Battery Backup in order to provide a solution. The idea of a power bank external battery, is that it acts as a portable charger to USB powered devices when there is no access to mains electricity. Exactly what I was looking for. The Tecknet iEP1500 isn’t just limited to bicycle touring of course. Hikers, campers, festival goers, and even conference or event attendees will all find a use for it.

Thought I would hold the Tecknet iEP1500 Power Bank up in front of a collage of travel photos!

So, let’s start with the basics. The Tecknet iEP1500 Power Bank can hold 15000 mAh, although to be honest, I haven’t got a clue what that actually means. I do know, that the more mAh a portable battery holds, the more recharges it will be able to give though. This is one of the larger capacity powerbanks on the market, and so was immediately attractive to me. I had some initial concerns that the device would be too bulky, but it’s really no bigger than a TV remote control. So far, so good.

In terms of charging, most people seem to think they can get between 4 and 5 full smartphone recharges out of the Tecknet iEP1500 Power Bank. I was looking to power a range of devices such as my Garmin Touring Pro Cycling GPS, Sony MP3 Player, Samsung Galaxy S4 and Iconia A1 tablet computer. Each of these devices takes a different amount of charge to get them to full, and my week long bicycle tour around the Fens of East Anglia provided the perfect opportunity to give this bit of kit a good test. Below, is a YouTube video that I have made which gives the product a thorough review as well. Please let me know if you like it (or not!). I am trying to include more video in this bicycle touring blog, and could do with peoples feedback. Beneath the video in this article, I have included some stats and my conclusions, so don’t leave after watching!

After charging the Tecknet iEP1500 Power Bank to full when at home before leaving, I took it out on the road with me for my bicycle tour. Diligent to the end (and also rather boringly), I kept a list of each charge that I made during the trip, listed below.


Day 1
GPS was down to 34%. Recharged to 100%


Phone was down to 4%. Recharged to 100%
GPS was down to 8%. Recharged to 66%


Day 3
Found a pub to recharge my phone in! Note – If I was cycling around the world, I would have plugged the Tecknet iEP1500 Power Bank into the wall with the phone charging out of it. It does happily charge one device at the same time as charging itself, but struggles with two devices.


Day 4
GPS down to 33%. Recharged to 100%
Phone down to 18%. Recharged to 95%


Day 5
GPS down to 25%. Recharged to 100%


Day 6
GPS down to 28%. Recharged  to 100%
Phone down to (??). Recharged to (??). – Sorry, didn’t make a note of this, but this was the last charge I made, and the Powerbank was empty after this. It was enough to get me home on the last day!


Hope those stats didn’t bore you too much, but I guess its the sort of thing that people need to know! Right, time for some conclusions then.


The Tecknet iEP1500 Power Bank – My Conclusions

It’s a rare day when a product matches and then exceeds your expectations, but this powerbank did just that. When I set out on the one week cycle tour of the Fens I thought I might need to recharge it at some point during the trip, but in the end, there was no need. It had enough power to keep my GPS live (my priority), and also to charge my phone every couple of days (secondary importance). As I was reasonably careful with the power I used on my gadgets, I never needed to use it to charge the tablet computer or other devices. And this is fine. This was a realistic test of the Tecknet iEP1500 Power Bank under bicycle touring conditions. Normally, when cycling around the world, I get to plug something into a wall every 7 days or so, and this is the perfect back up for in between those times.

It actually got me thinking a little more about power. I have been considering becoming “self sufficient” in terms of power on my next tour, which means either carrying solar or buying a dynamo. The Tecknet iEP1500 Power Bank is so good though, that I am seriously considering doing neither, but instead buying another powerbank so that I have two. Then, I can recharge them both on those occasions that I stay somewhere with power, along with all my other gadgets. This should mean that I could then run everything for between two and three weeks before needing to charge them all up again. It’s something I am going to think about further, as it will save me quite a bit of money and weight for my next trip.

To finalise then. The Tecknet iEP1500 Power Bank is a great bit of kit. Although the reason I have it is for bicycle touring, almost everyone that owns tech gear can find a use for it. Inexpensive, reasonably lightweight and small, you could even keep one at home to charge your phone if you get a power cut in your area.

  1. Okay this is scary: yesterday I googled for something like this and today you share this post with me on StumbleUpon.
    Are you watching me???? 😀

  2. Vanessa @ Green Global Travel says:

    Seems like a handy little device for camping, hiking, and biking! I would mainly use something like that for just GPS too, which hogs a lot of energy ironically. Thanks for sharing your review!

  3. I have been using a power pack for some time and love it however I have now bought for a small cost something better! If you have a hub dynamo which I am a massive fan of, for less than £20 I have bought a power converter which simply plugs into the dynamo, as I rarely use my lights in the daytime I thought what a waste of juice, some research on the tinterweb and bingo, there is enough juice produced to charge my S3, I have found I could have the screen on with this plugged in and it keeps it ticking over without losing charge from about 10mph. Weight is 87grams, much lighter than the power pack.

    • I am still working out whether solar or a hub dynamo would be better for me. (i suppose in a perfect world both!). I was thinking much along the same lines as yourself, but rather than charge the phone directly (which I don’t need on all the time), have it linked into charging the powerbank.
