B‑Series charging cart is a cost‑optimized mobile storage & bulk‑charging cabinet built with reinforced engineering‑plastic frame plus cold‑rolled steel inner structure, dedicated for K‑12 schools, training centres and library shared‑device fleets. This platform covers rich configurable variants: standard USB‑A, quick‑charge FUSB, data‑sync SYNC and full‑featured Type‑C editions, supporting 32 / 48 / 64‑bay device capacity. Unique rear isolated high‑voltage compartment keeps power circuits segregated from student‑accessible front storage zone, improving classroom safety level. Integrated leakage‑current protection, temperature monitoring, individual‑port LED charging indicators and active cooling fans are equipped as baseline. Universal 110‑240VAC wide‑range input adapts global education‑project mains conditions. 5‑inch brake‑equipped casters and ergonomic integrated push handle allow easy relocation between classrooms. Lockable single‑open‑iron‑door provides anti‑theft protection for tablets and lightweight Chromebooks, delivering an affordable all‑in‑one charging‑and‑storage solution for educational fleet management.
1.Engineering‑plastic Reinforced Outer‑frame Structure
High‑impact modified plastic outer frame lowers overall unit weight compared to full‑metal cabinet, meanwhile resisting scratch and impact damage in busy daily K‑12 classroom environment. Rounded corner treatment eliminates sharp‑edge safety hazards for student‑contact scenarios.
2. Rich Multi‑variant Port Configuration Choices
One hardware platform supports four functional variants: basic USB‑A charging, FUSB quick‑charging, SYNC simultaneous charge‑and‑data‑sync, Type‑C fast‑charging. Buyers select exact port‑type matching their existing tablet / Chromebook fleet without switching cart chassis.
3. Independent Isolated Rear High‑voltage Compartment
Power‑supply and high‑voltage wiring are fully confined inside rear‑side locked isolation cavity. Students cannot touch mains‑related circuits from front device‑storage zone, greatly lowering electric‑shock risks for primary‑and‑secondary‑school deployment.
4. Complete Built‑in Safety‑cooling Suite
Leakage‑protection circuit, temperature surveillance, per‑port charging‑status LED indicators and multi‑fan active cooling come factory‑pre‑installed. Real‑time thermal monitoring prevents overheating risk during long‑duration bulk overnight‑charging cycles.
5. Secure Mobile All‑in‑one Charge‑and‑store Design
Lockable single iron‑door prevents device theft when cart is unattended. Brake‑fitted casters plus integrated push‑handle permit effortless moving across classrooms, training halls and library zones.
6. Order‑flexible Bay‑count Selection
32 / 48 / 64‑slot options match different‑scale teaching‑device fleets, helping schools control procurement budget and avoid paying for unused vacant storage bays.
Compared with HI‑SUN A&D‑Series charging cart：
1.Material & cost positioning difference: A&D‑Series uses steel‑aluminum hybrid reinforced frame targeting large‑capacity high‑end projects; B‑Series adopts engineering‑plastic outer‑frame for cost‑optimized education‑tender budgets.
2. Unique isolated rear high‑voltage cavity: B‑Series features independent locked rear power‑compartment for student‑safety‑focused K12 scenarios, this dedicated isolation‑cavity is not implemented on A&D‑Series.
3. Diversified port‑function variants: B‑Series supports four configurable port‑modes including SYNC data‑sync and Type‑C fast‑charge on identical cart chassis; A&D‑Series focuses mainly on basic bulk‑charging requirement.
Compared with generic market education charging trolleys：
1.Student‑oriented high‑voltage isolation‑cavity: Many low‑cost competing carts expose power‑wiring inside front‑open storage area. B‑Series physically segregates mains circuits to rear‑locked compartment, meeting strict public‑school safety‑audit check‑lists.
2. Multiple port‑function variants on unified chassis: Most competitors separate charging / data‑sync / fast‑charge into totally different cart models. B‑Series shares identical mechanical cabinet, only swapping internal port‑boards for different functional demands, simplifying integrator stock‑management.
3. Full pre‑integrated safety‑cooling package: Plenty cheap trolleys only add simple passive ventilation slots without fans or thermal‑monitoring. B‑Series ships complete active‑fan cooling plus temperature‑leakage dual‑protection out‑of‑factory.

Q1: What is the main difference between B‑Series and A&D‑Series HI‑SUN charging cart?
A: B‑Series adopts engineering‑plastic outer‑frame with rear‑side isolated high‑voltage cavity, multiple port‑function variants, cost‑optimized for K‑12 school‑budget‑limited tender projects. A&D‑Series is steel‑aluminum hybrid heavy‑duty model, targeting large‑scale high‑end enterprise‑education deployments.
Q2: What do SYNC / FUSB / TYPE‑C variants stand for?
A:
‑ USB: standard 5V2.1A basic‑charging only;
‑ FUSB: quick‑charge capability;
‑ SYNC: support simultaneous charging + device data‑synchronization;
‑ TYPE‑C: native USB‑C fast‑charge ports for modern Chromebooks & tablets.
Q3: Is high‑voltage power wiring accessible for students?
A: No. All mains‑related circuits are sealed inside locked rear‑isolated compartment; front‑storage zone only exposes low‑voltage USB ports for student operation.
Q4: Does B‑Series support 110V overseas mains environment?
A: Yes, native 110‑240V wide‑range AC input, no extra voltage‑converter required for most global‑region education‑site deployments.
Q5: Can I switch port‑function variant after cart delivery?
A: Yes, internal port‑board can be swapped with optional upgrade kits for bulk‑project orders.
Q6: Can cart door remain locked while performing bulk‑charging cycles?
A: Yes, keep door locked during charging workflow; built‑in active‑fan cooling system guarantees proper heat dissipation.
