Power banks

Is a "semi-solid" power bank worth choosing over regular lithium-ion? The gel-electrolyte mechanism and what "harder to ignite, not fireproof" means, the small weight difference within the same series, why cycle life varies by product, and which kinds of use benefit—summarized in a decision table from makers' stated specs.

Should you pick a power bank with a built-in cable or one with ports only? Four axes—never forgetting the cable, built-in cables usually can't be replaced, thickness and weight, and choosing cable length and type—lead to a decision table of who each suits and when it fails. Compared with Anker Nano, Zolo, and CIO SMARTCOBY Pro SLIM as examples.

A decision guide that starts from how many charges you want and how much weight you'll carry. Rated mAh vs what actually reaches your phone (Wh and conversion loss), typical weight and charge counts for the 5,000 / 10,000 / 20,000mAh classes, the 160Wh airline limit, who each class suits and where it fails, then links to the comparisons for each class.

Choosing an iPhone power bank means deciding between MagSafe (wireless) and wired (USB-C). We compare charging speed, loss (heat and efficiency), portability, and pricing logic using stated specs, and say which to pick by use—including models that do both.

Is it true you should only charge your battery to 80%? This guide explains how lithium-ion batteries degrade, lays out both sides of the '80% rule,' and shares practical charging habits you can start today to make your battery last.

A power bank fire is a chain: internal short circuit → heat → the separator melts → more shorting → flammable electrolyte vaporizes and burns. This explainer diagrams that thermal-runaway chain, then shows which link semi-solid-state cells (gel electrolyte), lithium iron phosphate (LFP), and Anker's Neo Lithium-ion (NLB) each try to break—so you can decide what to buy and how to use it.

A complete guide for anyone who just bought a power bank and isn't sure how to use it. Covers charging the unit, reading the ports (input/output), thinking about capacity (mAh), using it safely, and care, storage, and lifespan—explained for beginners.

A parked car in midsummer—and even a pocket in the heat—is a harsh, high-temperature environment for a power bank. This guide explains why heat is risky, how to store and use your power bank in summer, the warning signs like swelling, and how to choose a reliable product.

Fast drain, slow charging, or a swollen case mean it's time. Never put a power bank in household trash—use JBRC collection boxes or your city's small-appliance program, with extra care for a swollen unit. Step-by-step disposal, plus how to choose a safer replacement.

The first thing to check when buying a power bank in Japan is the PSE mark. This guide explains what it means, how to spot it, how to choose and use a power bank to lower fire risk, and how to recognize products worth avoiding.

Since April 24, 2026, Japan allows only 2 power banks per passenger in the cabin (160Wh max each), and you can't charge a power bank or charge your phone from it during the flight. Plus the carry-on-only and seat rules, and a quick mAh-to-Wh check.

Charging by Qi2 25W, heat can make your iPhone throttle charging. Enter MagSafe-compatible power banks that advertise cooling or temperature control. The liquid-cooled (CryoPulse) UGREEN MagFlow Pro, the CIO SS10K that monitors internal temperature and limits output, and the standard Qi2.2 25W CIO Pro 10K—compared by cooling approach, output, and capacity.
