The Voltas Mega 70B listing offers a larger 70 L tank, while the Vego Frost I listing has seven speed settings and remote support. On those specifications alone, neither is an automatic winner: tank capacity affects refill frequency, not proven cooling performance, and the model details need verification before purchase. The Voltas manufacturer page covers a product called Mega 70, model 4810395—not explicitly Mega 70B—and the Vego listing currently says Frost I is unavailable.
How the listed specifications compare
The figures below come from secondary product listings updated by Gadgets 360: the Voltas Mega 70B page on 5 September 2026 and the Vego Frost I page on 28 September 2026. They are listing specifications, not results from a shared performance test. Voltas’s official Mega 70 page describes a differently identified product, so its specifications should not be combined with the Mega 70B listing.
| Feature | Voltas Mega 70B listing | Vego Frost I listing |
|---|---|---|
| Cooler type and tank | Desert cooler; 70 L | Desert cooler; 42 L |
| Cooling media | Wood wool | Honeycomb |
| Air delivery | Blower | Blower |
| Speed settings | 3 | 7 |
| Remote | No | Yes |
| Other listed features | 230 V / 50 Hz / single phase; water-level and overflow indicators; four castors | 1350 RPM; empty-tank, water-level and overflow indicators |
| Dimensions and weight | Not stated on the listing | 40.5 × 90 × 40.5 cm; 9 kg |
| Advertised coverage | 22.22 sq ft | 250 sq ft |
| Warranty and status | Secondary listing says one year against manufacturing defects; verify the offer terms | Listing says one year, covering electrical parts but excluding plastic components; currently unavailable |
The coverage figures are not a reliable head-to-head basis: the listings do not provide a shared test method or explain the substantial difference. Treat them as claims attached to their respective listings, not as a room-size recommendation. Neither tank capacity nor pad type alone establishes how effectively a cooler will cool a particular space.
What the larger tank does—and does not—tell you
The listed 70 L Mega 70B holds 28 L more water than the Frost I’s listed 42 L tank. That can mean fewer refills when other conditions are similar, but actual refill frequency depends on use and operating conditions. It does not show that the Mega 70B cools faster, reaches a larger area, or performs better.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Controls and cooling media: the listed trade-off
On the secondary listings, the Frost I has seven speeds and a remote, versus three speeds and no remote for the Mega 70B. Those controls may matter if you want more adjustment or to change settings from across a room. Both are listed with blowers, but their cooling media differ: wood wool for the Mega 70B and honeycomb for the Frost I. Confirm that the actual product being offered matches these model-specific details.
Check the Voltas model identity before relying on specifications
Voltas’s official product page identifies a “Desert Air Cooler Mega 70,” model 4810395. It states a 70 L tank, honeycomb padding, turbo air throw and inverter operation, and shows the product in white-grey. Those are manufacturer-stated details for Mega 70 / 4810395; they do not establish that it is the same configuration as the Mega 70B listing, which says wood-wool media.

For the Mega 70B specifications above, the source is the Gadgets 360 secondary listing, not a manufacturer page confirming that exact variant. Before ordering, compare the seller’s exact model or SKU with the product rating plate, and check the offer’s specifications against the item that will be delivered. Do not assume that “Mega 70” and “Mega 70B” are interchangeable names.

The Frost I listing reports that the product is currently unavailable. Its stated one-year warranty covers electrical parts and excludes plastic components, according to that listing; confirm the terms with a seller if stock appears elsewhere. The Mega 70B secondary listing says one year against manufacturing defects, but the applicable terms should be checked for the exact offer.

Voltas’s official Mega 70 page includes a product purchase flow and lists a comprehensive air-cooler AMC. That does not confirm local stock, that the AMC applies to Mega 70B, or that service is available in your area. Check the model, delivery location, service coverage and written warranty before paying. The Frost I’s detailed specifications and availability information in the cited sources are also from a secondary listing; no official Vego product page or manual is established here.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Which cooler should you choose?
Consider the Mega 70B if
- You prioritize the larger listed 70 L tank and potentially fewer refills.
- Three speeds and manual controls are sufficient for your use.
- You can verify that the seller’s item is actually Mega 70B and confirm its warranty and local service terms.
Consider the Frost I if
- Seven listed speed settings and remote support are more useful to you than a larger tank.
- You can find a legitimate current offer and verify stock, warranty coverage and service support, since the cited listing reports it unavailable.
If neither listing can be verified
Do not decide from the advertised coverage numbers or the shared “70 L” name alone. Ask the seller for the exact model/SKU, a photo of the rating plate or packaging, written warranty terms, current delivery availability and confirmation of service in your area. If the seller cannot reconcile Mega 70B with the manufacturer’s Mega 70 / 4810395, treat the identity and specifications as unconfirmed.
