Detailed overview: Aferiy Nano100 LiFePO4 99 Wh power bank with retractable cable
The Aferiy Nano100 is a compact power bank that bets on a technology still rare at this size: LiFePO4 (lithium iron phosphate) cells. This chemistry, used in power stations, offers a far longer lifespan than conventional lithium-ion, with over 2000 charge cycles claimed, against 300 to 500 for an ordinary power bank. In practice, you keep the Nano100 for years without seeing its capacity collapse.
On capacity, it shows 99.2 Wh, or 31,000 mAh, a figure chosen to stay just under the 100 Wh cabin limit set by most airlines. It recharges a smartphone a good ten times, or a laptop once or twice, and easily powers a tablet, a drone or a handheld console.
The power is there: up to 100 W on the main USB-C port, enough to recharge a MacBook or an ultrabook at full speed. It has two USB-C ports (100 W and 45 W) and a USB-A port, for 145 W in total and up to three devices at once. A retractable 80 cm USB-C cable is built into the body, delivering 100 W and saving a separate cord. A display shows in real time the charge level, the input and output power and the remaining time.
It refills itself very fast, 100% in about 1.5 hours with a 100 W input, and pass-through lets you use it while it charges. At 1.1 kg, it is heavier than a lithium-ion bank of similar capacity, the accepted trade-off for the ruggedness of LiFePO4. For travel, mobile work and heavy long-term use, the Aferiy Nano100 is one of the most accomplished power banks in its class.

Comparison
At around 65, the Aferiy Nano100 competes with premium 100 W and higher power banks, through searches like "best LiFePO4 power bank" or "100 Wh flight power bank". Here is how it stacks up against three alternatives: the Anker 737 (PowerCore 24K), the Ugreen Nexode 145W 25000 and a conventional 100 W power bank.
| Criterion | Aferiy Nano100 | Anker 737 (24K) | Ugreen Nexode 25000 | 100 W power bank |
|---|---|---|---|---|
| Capacity | 99 Wh | 86 Wh | 93 Wh | 74 Wh |
| Chemistry | LiFePO4 (2000+ cycles) | Li-ion | Li-ion | Li-ion |
| Max power | 100 W | 140 W | 145 W | 100 W |
| Built-in cable | Yes (retractable) | No | No | Varies |
| Observed price | ≈ 65 | ≈ 110 | ≈ 90 | ≈ 45 |
In short, the Aferiy Nano100 stands out for its very durable LiFePO4 chemistry and its built-in retractable USB-C cable, two rare assets on a pocket bank. The Anker 737 and the Ugreen push the power higher (140-145 W) and weigh a little less, but rely on conventional lithium-ion, less enduring over time. An entry-level 100 W power bank stays cheaper, but with lower capacity and longevity. For anyone who values durability and travel convenience, the Nano100 is an excellent choice.

Our tester's review: Guillaume Hoarau
The Nano100 is one of those new banks that blur the line between the big power bank and the mini power station. Its real strength is the LiFePO4 chemistry: where a conventional power bank wears out after a few hundred cycles, it promises over 2000, enough to keep it for years with no notable loss. The 100 W over USB-C is a treat when travelling, recharging a MacBook or an ultrabook at full speed, and the built-in retractable USB-C cable is wonderfully handy, no more hunting for a cord. The clear display shows charge, input and output power, and its 99 Wh let it pass as cabin baggage without argument. You can plug in three devices at once. Two honest reservations: at 1.1 kg it is heavier than a Li-ion bank of similar capacity, a direct result of the LiFePO4 chemistry, and its price places it above entry-level banks. But for anyone who wants a durable, powerful and genuinely portable bank, it is a success.
