New Age 80,000mAh vs itel IESS-320T: Which 130W Backup Power Solution Should You Buy?

At first glance, the New Age Heavy Duty 80,000mAh and itel IESS-320T Power Go look remarkably similar. Both weigh around 3.5kg. Both advertise up to 130W total output. Both can charge laptops, smartphones and several devices simultaneously. Their Nigerian prices can even overlap.

But after breaking down their specifications, these are two different approaches to portable electricity. The New Age is the better fit for high-power USB-C laptop charging, delivering up to 100W through USB-C. The itel is the more complete small backup-power system, combining a 320Wh LiFePO₄ battery with USB, DC and solar charging support.

Which one should you buy? It depends much more on what you intend to power than the 130W printed on both boxes.

New Age 80,000mAh vs itel IESS-320T specifications

The New Age energy figure is an approximation: 80Ah × a typical 3.7V nominal lithium-cell voltage ≈ 296Wh. New Age's specification lists capacity in mAh rather than Wh.

Battery: 80,000mAh and 320Wh aren't as far apart as they sound

The first mistake would be comparing 80,000mAh against 100,000mAh and assuming the itel stores 25% more usable energy.

Watt-hours are the better measurement when comparing large batteries. Using a typical 3.7V nominal lithium-cell voltage, the New Age's advertised 80,000mAh works out to 296Wh before conversion losses. The itel is explicitly rated at 320Wh.

That puts them much closer than their marketing numbers suggest. The more important difference is battery chemistry. The itel uses LiFePO₄, a chemistry particularly attractive for backup systems because of its cycle life and thermal characteristics. Current retailer specifications advertise more than 3,000 cycles for the IESS-320T.

If I were buying a battery specifically for frequent home or office backup, that would carry significant weight in my decision.

Laptop charging: New Age has a major advantage

Here the comparison flips. The New Age's strongest specification is its up-to-100W USB-C output. That makes it better matched to higher-powered USB-C laptops.

A 65W ultrabook should have plenty of headroom, while compatible laptops capable of accepting 100W USB Power Delivery can make fuller use of the output.

The itel IESS-320T's primary USB-C port reaches 65W, with its second Type-C connection topping out at 20W. Its four USB-A ports are rated at up to 20W each.

That means the itel's 130W total output does not mean you can send 130W into one laptop. The maximum available from its strongest USB-C connection is 65W.

For a MacBook Air, many business laptops and other 45–65W machines, that's sufficient. For larger MacBook Pro models, workstation-class notebooks or other USB-C laptops that can take 100W, I would choose the New Age.

The itel is much more than a large power bank

The IESS-320T starts pulling ahead once we stop talking exclusively about USB devices. Its 320Wh LiFePO₄ battery supports DC output and up to 100W charging input, including compatible solar charging. That makes it more useful as an actual backup-energy system.

It can run a Wi-Fi router, DC lighting, compatible DC fan, laptop and other low-power equipment rather than simply recharging portable electronics.

The product has a maximum battery-mode conversion efficiency of at least 93%, two USB-C outputs, four USB-A outputs and DC connections. Its physical dimensions are approximately 190 × 65 × 190mm.

This is the model I would rather leave beside a workstation during an outage. The New Age, meanwhile, makes more sense if nearly everything you own charges over USB.

Both say 130W, but don't misunderstand that number

This is perhaps the most important buying point. Neither device is a 130W appliance power station in the conventional sense.

130W is the combined maximum output. You need to consider the individual port limit and the power requirements of whatever you're connecting. A 10W router, 20W phone and 65W laptop fall comfortably within this class of product. A kettle, microwave, pressing iron, heater or conventional refrigerator does not.

The itel is approximately 4–5 hours for 50–65W Type-C laptops, 18–25 hours for 10–15W routers and 25–30+ hours for a single 10W LED light. Those figures are useful as guidance, although actual runtime will vary with load and conversion losses.

Portability: surprisingly, neither wins

Both are listed at around 3.5kg. That surprised me because the New Age looks more like a conventional oversized power bank, while the itel is explicitly positioned as a portable power station.

At this weight, I wouldn't call either an everyday backpack accessory. They are transportable rather than pocket-portable: reasonable for moving between home, office, car, studio or worksite, but heavy if you're carrying one all day.

Nigeria price: the itel creates a value problem for New Age

Our October 2026 price check makes this comparison particularly interesting.

The New Age promotional price is ₦112,200, while we found the same 80,000mAh model at around ₦96,629 on CDcare, ₦99,500 at JIX Accessories and ₦108,000 on Jumia. Prices vary substantially by seller.

The itel IESS-320T is currently listed at ₦107,800–₦115,500 on the itel Solar storefront. That overlap changes the recommendation. At roughly the same ₦110,000 budget, the itel gives you 320Wh storage, LiFePO₄ chemistry, solar/DC charging capability and a broader backup-power design.

The New Age fights back with one important advantage: 100W USB-C laptop output versus 65W on the itel.

Which should you buy?

For most people building a small backup setup, I would buy the itel IESS-320T. Its LiFePO₄ battery, 320Wh rating, solar charging capability and broader selection of outputs make it the more versatile product. At current Nigerian prices, you're getting substantially more flexibility without paying substantially more.

But there is one group for whom I would choose the New Age 80,000mAh instead: laptop-heavy users. If your primary requirement is charging a USB-C laptop that can draw 80W, 90W or 100W, the New Age's stronger USB-C output matters more than the itel's extra backup features.

So the decision is actually quite simple: Buy the New Age if your laptop is the priority. Buy the itel if backup power is the priority.

For a developer working remotely with a high-powered USB-C laptop, the New Age makes sense. For a home office trying to keep a 65W laptop, router, phones and DC accessories running through outages, I would take the itel.

And if you need to run appliances drawing substantially more than 130W, I would skip both and move up to a larger portable power station.
