Size is listed as 150×24.9×115.8 mm, protection as over-charge, over-discharge and over-heat, recharge cycle as more than 500 times, and standard charge time as around five hours, with an LED indicator and an on/off switch.

- 7 x 12V models with full spec tables
- Portable stations and hybrid NiMH fitments
- Certificates available upon request
No founding year, headcount, phone or named contact is published on this site: those records conflict between sources and are not settled. Contact goes through the inquiry form.
The two capacities are the key choice on this page. They share a size, a voltage and a protection set in the listing, and differ in listed energy (74.88Wh against 96.48Wh). A buyer should confirm which capacity is actually supplied for the listing ordered, rather than assuming the larger figure.

Values are recorded exactly as listed for this model. Where a figure is absent, it was not read for this model and is not inferred from another model.
Options are not a shipped configuration
Charger plug types named in the listing — US, UK, EU, South African, national and universal — are listing options. They are not a promise that every plug type ships in the box, and this page does not present them as a shipped configuration.
Temperatures listed for this model are operating −20℃ to 60℃, charging 0℃ to 45℃ and storage −20℃ to 45℃. Certificates follow the site-wide line: “Certificates available upon request.” No certificate number is published.
A third-party manual copy names a PB240 series with its own capacities and outputs. That series has no model page on this site, because a manual hosted on a third-party site is corroboration only, not a primary source. Before payment, confirm MOQ, lead time, voltage, warranty and certification scope for your order.
Capacities and cell arrangement, as listed
The two capacities share the cell arrangement as listed (4S2P, 3.7V, 20800mAh), the same size and the same protection set. Recharge cycle is listed as more than 500 times with a standard charge time of around five hours, and the bank carries an LED indicator and an on/off switch. Those are listing figures for this bank, and the capacity actually supplied for an order must be confirmed, since the two capacities share every other listed figure.
Before ordering
Before payment, confirm MOQ, lead time, voltage, warranty and certification scope for your order.
Confirm the specification for the model actually ordered, not for a neighbouring model or a series range.
